The issue of the capacity of portable devices and their “endurance” in operation is always relevant. Each tablet or smartphone is charged daily, and sometimes several times a day, depending on the intensity of use. And, you see, it’s not very pleasant to watch how the device you’re working with quickly discharges and forces you to give up working with it. Sometimes this can make you put everything aside and just “stare at the ceiling.” If you're on a train somewhere, stuck in a traffic jam, or even waiting in line somewhere, this is important.

In some cases, the need to extend the life of your battery by any means becomes even more urgent. For example, this applies to situations when you are working with a tablet, downloading some important documents from it, or creating a presentation. The success of your work may depend on whether the gadget will function or simply turn off, reporting a low charge.

Therefore, in this article we will talk about a solution that can make life easier for many mobile device users. This is an external battery for tablets, which allows you to increase the service life of the device. Thanks to this, the actual time during which your gadget will serve you can increase several times. The main thing is to always keep one on hand.

battery?

We will start with a general overview of the device described in the article. So to speak, we’ll simply describe how such a gadget can be useful, what it looks like, and what principle it is based on.

After all, we know about the internal battery, which is installed in all smartphones, that it is the power source for our electronic devices. Without it, it is simply impossible to ensure the operation of any gadget. It looks like a flat metal container with miniature dimensions (depending on the tablet model). The internal battery is installed under the back cover, thus not creating problems in operation.

In addition, there is also an external battery for mobile devices. It can be positioned as a separate device, some kind of addition to your phone or tablet. The form in which such an accessory will be expressed can also differ significantly - some of them are sold in the form of key rings, while others are supplied to the market in the form of an entire bag. There are also a lot of options for such devices, they all have different characteristics and technical data.

External and telephones have a number of advantages. By connecting your device to such a “key fob”, you can additionally charge it and, accordingly, extend its operating time. This is the same as having an outlet within reach at all times. As you understand, this is very convenient, which is why such batteries for tablets and smartphones are in demand today more than ever.

Kinds

There are many classifications of such devices, depending on different criteria. You can first distinguish the capacity of such batteries - it can be 1000 or 20,000 mAh; we can talk about the types of charging such devices - using a network adapter (directly from charging) or via a microUSB cable; Another difference lies in the voltage that the battery supplies to the gadget being charged. The last factor, for example, will affect how quickly you can charge the device. This is especially important if you are looking for an external battery for tablets, which, in principle, have more capacious batteries, which means they must be connected to the network longer.

There are separate lines of batteries that operate using solar energy. These, for example, have miniature solar panels installed, the power of which is quite enough to charge a smartphone. You can also divide devices into those that do not have any interface (they are organized as simply as possible), as well as those that have a separate control panel where charge indicators are located.

In the end, such batteries can be distinguished by the materials used to create the case, by color, texture, size, and so on.

Price

If you are looking for an external battery for tablets, you should immediately determine which device from which price segment will be of interest to you primarily. After all, there are different models that can demonstrate completely different charging capabilities. For example, the simplest Blacksmith model for $10 is one thing, and a device with maximum capacity for $50-60 is another thing (for example, Incipio Offgrid for Samsung S6).

In this regard, let me immediately define two facets within which you can make choices. The cheapest products are definitely those released at Chinese auctions. There, a portable charger can be purchased for a couple of dollars, having concluded a fairly good deal with the seller. However, you should be careful, since Chinese suppliers often deceive about the actual battery capacity: where 20 thousand mAh is indicated, there may actually be only 1000. Such cases, unfortunately, are not isolated.

Another way out is to buy the most real, original accessory. For example, this could be a portable battery for your iPad. Due to the fact that such a product is approved by inspection authorities, its value increases. People’s attitude towards Apple technologies also plays an important role here.

Capacity

One of the most important factors characterizing a portable charger, as you already understood, is capacity. It indicates how long the service life of a particular device can last. As you know, the “endurance” of the battery of your smartphone or tablet is also measured in this value. So what does this mean?

Let's give a simple example to make it clearer. The phone has a battery with a capacity of 2500 mAh, while the additional battery has a capacity of as much as 5000. Theoretically, the charge that the portable battery accumulates should be enough to “refill” the phone’s battery twice. However, in practice, this may only be “one and a half charges”, since the rest of the energy will disappear, taking into account the technical features of the device. Experts say that the older the battery, the shorter the period during which it holds a charge.

The logic turns out to be simple: the more capacious your external battery for mobile devices is, the more times you can “replenish” the charge of your smartphone.

True, in this case you will need to look for some balance between two parameters - the size of the battery and its cost. The more capacious the battery, the larger its dimensions and final cost will be. Therefore, today small batteries are in greater demand on sale, which are enough to charge a smartphone battery by 60-80 percent. This is enough to keep the device working until the end of the working day.

Models

In order not to talk about some abstract categories, I would like to turn to specific devices on the market. In this way, we can characterize them and compare them with other accessories of the same kind.

So, let’s immediately note that the manufacturers of gadgets from this line are either companies that produce accessories for smartphones (cases and screen films), or brands that are present directly on the electronics market. Among the first are, for example, the Ozaki company with their O!tool Battery T52, made in an original design; The second one includes Xiaomi Power Bank (10,400 mAh). There are also fairly well-known companies that have at least one additional battery in their lineup. These are: ZenPower (model from Asus), YooBao, Mophie, Bootcase, PowerPlant, Drobak Trust Urban Revolt and many others. Some of the designated brands represent only one or two models, while others specialize in producing entire lines.

Comparison

It is best to compare different versions of batteries with each other to understand what they are capable of. For example, there are two identical models: Nomi A052 and Xiaomi Power Bank. Both devices have a capacity of 5200 mAh (like the internal battery for a Samsung tablet), and the cost of the first is slightly lower: $10 and $13, respectively. What can we say about the comparison?

First of all, these are the materials of the case. It’s not for nothing that the “Chinese” Nomi is cheaper than the same “Chinese” of its opponents. The second point is reliability. If Mi products are presented more successfully in the eyes of the buyer than “Nomi”, then the latter is something quite risky (after all, you don’t know how long it will serve you).

Another example of creating such “bundles” of models is OnePlus Power Bank and FrimeCom 6SO. The first device will cost 17, and the second - 21 dollars, although the capacity of each is 10 thousand mAh. True, the second one has a small competitive advantage, which in some cases can be really lucky: the presence of a panel for charging the device using sunlight. This battery is suitable for tablets (including Samsung Galaxy), and you can work with it at home or in the office, placing it on the windowsill.

Compact ones include the Mophie keychain (1000 mAh capacity) and Trust Urban Revolt (4400 mAh). Obviously, the second device (made in the form of a “finger” rectangular accessory) can be called more voluminous. However, the first option will be more unobtrusive in everyday life. In addition, you can use such small batteries to temporarily recharge your gadgets.

Unfortunately, it is impossible to compare a large number of models within the scope of this article, since it would take too much time. Let’s just say that the entire portable battery market is divided into large batteries that can “keep” your gadget active for several days, and small “keychains” for carrying them in your bag and using them in the right situation. There are also original solutions, such as batteries built into the case. The latter are especially popular among Apple iPhone owners.

How to choose?

Let's say you have to buy one portable battery for your tablet or smartphone, but you don't know where to start in your search for the perfect device. We recommend that you first familiarize yourself with the technical data of your device.

For example, batteries are one thing (the battery capacity of which reaches 6-7 thousand mAh), and another is finding the optimal solution for your iPad mini. Be sure to read the instructions (or description on the Internet), where the capacity of the batteries will be indicated. Knowing this information, you can calculate which external battery is best suited and how many charges it should be oriented towards.

Tests

The second step is “testing”. Carry out a miniature test with the battery that interests you: hold it in your hands, see if it fits into your bag, and if it is the right weight for you. This can also be done directly in the store. And to find out how quickly it will charge your tablet battery (whether it’s Samsung or some other company, it doesn’t matter), check the characteristics of your charger. It should indicate the current voltage supplied when connected to the network.

This can be from 0.7 to 2 V (on average). If the characteristics of a portable device are higher than those marked, this means that the charging process will be faster (and vice versa). This will give you the opportunity to find out how the process of interacting with such a portable battery will differ from working with a conventional network adapter.

Finally, you can read reviews on online store sites, where the portable tablet battery you are interested in is described in more detail. Explay, Xiaomi, Lenovo and a number of other manufacturers publish some tests of certain gadgets on their equipment. Thus, if you find the same model, you will be sure of compatibility and excellent interaction in practice.

Advantages and disadvantages

In general, we can talk endlessly about the advantages of the gadgets that we describe in this article. This is a real way to increase the operating time of your device, make it non-volatile and truly portable. In addition, such accessories can become your real salvation somewhere on the road or at work if you had important information or documents on the tablet.

Among the shortcomings, their “wear and tear” should be noted. It is expressed, of course, not in physical damage to the device, but in the fact that over time the battery holds a charge weaker, which is why its service life is reduced. For this reason, the ability to charge other electronic devices (tablet or smartphone) is correspondingly reduced.

Such processes are normal, they occur with absolutely all batteries. The only solution may be to use some devices with solar panels. Imagine charging your tablet battery using solar energy!

conclusions

The electronics market offers a huge number of models of external or portable batteries. According to their purpose, they are positioned both as those that are used to work with a smartphone, and as chargers for tablets. This characteristic is determined by their capacitance and the level of output voltage.

Choosing a device that is suitable for your device is not so difficult. First of all, you should pay attention to its charge and compare it with the data from your device. Compare the capacity of the batteries to know how long such a battery will last for you. Next, decide on the current strength (which affects the charging speed).

The rest is purely a matter of taste. Since external batteries come in different types, have different colors and are made in literally a wide variety of forms, you can choose an accessory for yourself based on your own wishes. This is done very easily - think about which pocket of your bag you would like to carry it in, how often you will need it in everyday life, and so on. Also think about such a question as the possible choice of a device with solar panels in order to be able to replenish the charge on your smartphone or tablet using energy from a natural source.

Where can I buy?

Batteries for on-the-go charging are sold everywhere: in all electronics stores, in subway passages and even in communication stores. We would, of course, recommend ordering such a device from some online store, and there are a number of reasons for this. Firstly, you will have a wider choice if you buy the right model online. Secondly, such sites, as a rule, charge lower prices than real electronics supermarkets, so here such a product will cost you less. Thirdly, you can always place an order from abroad (for example, from Chinese auctions), where the cost is even lower.

It's no secret that modern mobile consumer electronics have one unpleasant feature, namely the need to constantly recharge the battery hidden in the case, due to which, in fact, the operation of the gadget is possible. The same applies to new generation phones, which, due to their technology and advanced functionality, have become excessively voracious in terms of energy consumption. No matter how long your smartphone runs on a single battery charge, it is still not enough, and provided that you use it quite often, the issue of extending battery life becomes even more relevant. In this material we will talk about portable batteries for mobile phones - about their characteristics and design features. We will also consider a number of interesting models that are relevant at the moment.

Why do you need a portable battery?

As mentioned above, the battery (that is, the battery) in modern smartphones requires constant recharging. Gadgets are becoming faster, more powerful, larger, but in terms of autonomy, almost nothing changes. The average battery life today rarely reaches 8 hours or more; under heavy load this value is reduced to 5 hours. And even if you stretch the existing capacity with all your might, it is almost impossible to achieve autonomy for at least two days. It sounds sad, but it's true, no matter what gadget manufacturers say. Naturally, the problem did not remain without a solution, and since it is not possible to significantly improve the autonomy of the gadgets themselves, then you can use an additional battery. In the case of old-style phones that can be disassembled, once you have full access to the battery, you can replace the main battery. But there are fewer and fewer such phones; they have been replaced by monolithic cases similar to the iPhone. In this case, the additional battery is an external portable battery for the phone.

How does a portable battery work?

As obvious as it may sound, an external portable battery works the same as a regular (internal) one. The changes concern a slightly modified design in accordance with the scope of application of such a battery. Essentially, this is a series of power cells that are soldered to a power controller (similar to those found in smartphones). Then ports for recharging the battery itself and one or more ports for charging smartphones, tablets, laptops and the like are built into this design. Despite the simplified design compared to a smartphone, the rechargeable battery works on the same principles as in a phone, therefore the battery remains the most dangerous object in any gadget. Like any other device, an external battery has a number of characteristics that you should rely on when choosing a portable battery for your phone. How to choose the right model based on its technical equipment and what is really worth paying attention to?

Portable battery capacity

The main parameter that you need to pay attention to when choosing a device. It is this indicator that determines how much additional “life” time your smartphone will receive, which means that in fact this figure indicates the efficiency of the battery as a whole. This value is directly related to the battery capacity of your smartphone. Just like the capacity of other compact batteries (smartphone, tablet or smartwatch), the battery capacity of an external battery is measured in ampere-hours, namely milliamp-hours. When choosing the optimal capacity value, first of all you need to find out the battery capacity of your smartphone (smartphones or tablet), and then find an external battery with a value of at least one and a half to two times more, so that you have the opportunity to recharge your phone (other gadget) at least once. Let's say your phone has a 2500 milliamp-hour battery. If you want to get at least one additional recharge cycle, then you should look for an external battery with a capacity of 4000-5000 milliamp-hours. It would seem that this is overkill, but in fact, the actual battery capacity always differs from that declared by the manufacturer (especially true for solutions from China). The device also loses charge even when inactive. The best option when purchasing would be a battery with a capacity of 6,000 milliamp-hours for smartphones and 12,000 milliamp-hours for tablets.

Discharge current

Everything is simple here: in order to share electricity with a phone or tablet, a portable battery needs a certain current strength. Typically, a smartphone needs one ampere (1A) to fully charge. With tablets and their giant batteries, a lot of power is needed, at least two amps (2A). Some portable batteries are equipped with several ports from one to three amps. This option is suitable for those who plan to charge several devices of different types at once. You can find out the exact information about how much current your gadget needs by looking at the label on the charger.

How to charge a portable phone battery?

Another serious point that careless buyers often overlook is the method of recharging the portable battery itself. The fact is that some models have a specific socket connection and are generally powered only from a computer or laptop, which has a detrimental effect on the speed and efficiency of charging. Such devices are outdated and are now almost never produced, but you can still come across them. It is better to make sure that the gadget you are purchasing is equipped with a standard micro-USB port and can be charged from the mains.

Design, size and weight

When choosing a device design, you should pay attention to two important details:

• The on and off button must be recessed into the body so that the gadget does not accidentally turn on in a bag or pocket and begin to supply energy to nowhere;
• The specified battery capacity must match its size; no one can fit a 12,000 milliamp-hour battery into a case the size of a watch.

Portable phone battery - how to choose?

Even knowing certain specifications and features of external batteries, the question of choice remains open, since a variety of companies are involved in the creation of such devices. Some make batteries exclusively for specific smartphones, while others make universal options. In some solutions, the emphasis is on external performance, in others on the technical aspect and reliability.

If you imagine an average solution that will definitely suit everyone, then it should have the following characteristics:

• Capacity from 6000 to 12,000.
• 1A port or several different ones at once.
• Weight no more than 500 grams.
• The price is approximately 1,000 rubles (anything that is much cheaper is also much inferior in quality).

This knowledge is already quite enough to start an independent search for a suitable battery, but it’s still worth adding specifics. Next, we will look at various portable batteries for phones. The rating of the most interesting solutions on the market, notable for their colorful exterior, unusual design or extremely low price, is presented below.

Xiaomi Mi Power Bank

Cost: 990 rubles.

Capacity: 10400 milliamp-hours.

A popular gadget from the Chinese company Xiaomi, which is famous for its dumping prices on fairly high-quality and well-designed devices. Xiaomi Mi Power Bank is no exception. This is a very compact and stylish gadget with a capacious battery inside. The finish is made of anodized aluminum in the style of a MacBook. High-quality, proven power cells from LG and Samsung are installed inside. As for the capacity, its actual value is 6250 milliamp hours. Xiaomi is honest with the buyer and explains this by saying that half of the capacity is wasted. This is a good portable battery for the Samsung Galaxy S6 phone as that is what the tests were done on and it can charge the battery twice. At the same time, the Mi Power Bank hardware is fully optimized to work with other modern smartphones. In general, we have an excellent portable battery for a phone, user reviews confirm this fact. Owners of the device praise its premium design, low cost and good ergonomics. There are also critical reviews, but they mainly concern defective samples and fakes.

OZAKI O!Tool D26

Cost: 2,490 rubles.

Capacity: 2600 milliamp-hours.

An extravagant and intricate battery robot that attracts with its unusual style and compact size. There is nothing remarkable about its design or capabilities. It will hardly be able to fully charge a modern smartphone, and its body is made of cheap plastic. If you are ready to sacrifice everything for a stylish toy that will look cool in your hands and easily fit even in a shirt pocket (the height of the gadget is only 6 centimeters), then you should pay attention to the brainchild of OZAKI, but at the same time prepare 2,490 rubles (by the way, for this money can buy two Xiaomi Mi Power Banks).

Apple Smart Battery Case

Cost: 9,790 rubles.

Capacity: 2365 milliamp-hours.

This gadget is made in the form factor of a case and has a very narrow focus - it is suitable only for three phone models: iPhone 6, iPhone 6s, iPhone 7. This battery has a number of interesting features. Firstly, it is made of expensive silicone, durable and resistant to damage. Secondly, it has a rather unusual design, namely a bulge in the central part of the case (where the battery is located). Thirdly, with this case you can simultaneously charge your smartphone and use the same cable. There are also disadvantages, which include the impressive cost and the ability to charge the iPhone only once. It turns out that we have before us an incredibly expensive gadget, with low capacity and a very contradictory design, but at the same time the only one that is tightly coupled with the iPhone (even at the software level) and thus gives the very emotions of integrity and thoughtfulness for which the Apple corporation is famous.

DEXP SOLAR 10

Cost: 1,890 rubles.

Capacity: 10,000 milliamp-hours.

This is perhaps the most inexpensive portable solar phone battery available. Yes, that’s right, the device can be charged using solar energy; for this purpose, a special panel is installed on its body that converts the sun’s rays into electricity. The gadget boasts two USB ports that supply current with different strengths (you can charge your phone or tablet). On a sunny day, SOLAR 10 will become an indispensable assistant, and if it rains, it can be charged from a regular electrical outlet or computer. The power type is selected manually by the user using a special key on the case.

Lepow Virtue

Cost: 3,989 rubles.

Another one that attracts attention with its bright appearance, but does not impress with other characteristics. The body is made of hard, matte plastic and small glass inserts. The lower part of the case is painted in a pleasant orange tint; the upper part has two displays: one of them displays a charge indicator, the other shows the same, but in the form of a pulsating neon heart. The gadget turned out to be heavy, not very functional, but at the same time surprisingly cute. Moreover, recently this beauty has dropped significantly in price. Prior to this, the high cost scared many users away from purchasing this miracle.

Powermonkey Extreme

Cost: 14,900 rub.

Capacity: 9000 milliamp-hours.

The most advanced portable battery on the list. A true Swiss Army knife in this area of ​​electronics. By purchasing Powermonkey Extreme, you get not only a classic battery, but also two solar ones. The kit includes a full set of adapters for different smartphones and tablets, and there are also modifications for connecting cameras and DVD players. There is a hard case for transportation and a compact strap (to hook onto a belt, for example). The battery itself is made of durable materials, as the device is designed for use in extreme conditions. Overall this is a good portable phone battery that can handle extreme conditions. Owners of the device, travelers and fishermen appreciated the gadget, singing its praises on various forums. Users complained only about the high cost.

A modern smartphone can run out of charge at the most inopportune moment, when you do not have access to an outlet. And during some kind of hike, difficulties are guaranteed to arise - even the best smartphone models cannot work on a single charge for more than three days, while an outing into nature with a tent can last for a whole week. Fortunately, this problem can be solved quite simply - just buy an external battery. In this article we will talk about such a device as an external battery for a phone, how to choose it.

Which brand should I choose an external battery?

Naturally, this niche of computer technology has its own production leaders, and these are the brands that users most often prefer.

Hiper

Products under this brand have only existed for a few years, but during this time they have won leading positions in various charts. At first, the manufacturer relied on high capacity - its main models can charge even a 10-inch tablet, and more than once. But over time, the product line expanded, resulting in less capacious models.

Important! Initially, the batteries from this manufacturer had a rough design, but today the situation has changed - there are models on the shelves with attractive colors and elegant curves.

Remax

This brand distributes the largest number of portable batteries. The user can easily choose a copy for himself, focusing on his needs. Many models have built-in LEDs that act as a flashlight.

Important! The capacity of such batteries reaches 30,000 mAh - this parameter will be enough to even charge a laptop a couple of times.

Samsung

This is a South Korean company that introduces a large number of unique technologies into its smartphones. It would probably be strange if the external batteries of this manufacturer did not contain interesting functions. The main one is support for relatively fast charging.

Important! If power is transferred to a compatible device, charging to 50% occurs in just 30 minutes or less.

Pay attention to the review.

Xiaomi

This is a Chinese company that started producing external batteries quite recently. Previously, it specialized only in the production of smartphones. The main feature of Xiaomi products is increased reliability. These batteries are not affected by power surges or any other troubles.

How to choose an external battery?

When choosing an external battery, you should think about how you will use it:

1. If you are going on a hike for many days, then you should look for a copy with a large supply of capacity. If you want to guarantee the evening operation of your smartphone, then you will be quite happy with an accessory with a capacity of no more than 5000 mAh.
2. You should also be interested in the number of connectors present. In particular, more capacious models may have a universal round-shaped connector. As a rule, the current output to it is more than 3 A - this makes it possible to charge the laptop.
3. In addition, dimensions should also be a concern. Technologies are gradually improving, thanks to which modern batteries with the same capacity become smaller in size.
4. Regarding the flashlight and solar battery, as a rule, they are used extremely rarely, so you should not focus too much on them when choosing a suitable device.

To choose an external battery for your smartphone , which will meet all the desired parameters, first you need to decide how exactly you are going to use it and for what gadgets. After weighing all the advantages and disadvantages, you can choose an accessory that will come to the rescue at any time.

How many times have you suffered from your smartphone running out of power at the most inopportune moment? What if you need to make an urgent call or wait for an important message? It’s good if there is an outlet or computer nearby that you can quickly charge your device from. But what if they are not there? The solution is to use an external battery (power bank). The Internet project “Be Mobile” has collected tips that will help you choose the best option for you.

First, let’s define what an external battery is and what its advantages are. An external battery or Power Bank is a portable high-capacity lithium-ion battery that can be used to charge a variety of mobile devices: phones, smartphones, tablets or e-readers. This battery is capable of storing energy within itself for a long time. You can take it with you to work, school, on a business trip or while traveling.

The portable charger can be made in various form factors with a housing made of plastic, polycarbonate or metal. On sale you can find models in the form of boxes, bars, disks, cones and tubes in a variety of colors.

The Power Bank is charged from the electrical network or from any device with a USB output (for example, a computer or laptop).

All external batteries are equipped with one or more USB ports. Modern phones, smartphones or tablets can be charged using a USB cable, which in most cases is included with the device.

id="sub0">

The main parameter when choosing an external battery is energy capacity. Everything here is simple and clear. The larger the capacity, the more energy the device stores, and the more expensive it is. Capacity is measured in mAh - milliamp hours.

Currently on sale you can find portable chargers with a capacity ranging from several hundred milliamp hours to several tens of thousands. You can estimate the level of charge you will need based on the battery capacity of your smartphone or tablet.

For example, in an average smartphone the battery has a capacity of 2,000 mAh, in high-performance and expensive models - from 2,500 to 3,000 mAh. This means that a fully charged 5,000 mAh external battery will be enough for 2-2.5 charging cycles. A fully charged 10,000 mAh external battery will last for 4-5 cycles. If portable charging is necessary for your tablet, then you should choose from models with a larger capacity, for example, 20 or 30 thousand mAh.

Currently produced portable power sources use lithium-ion or lithium-polymer batteries. Depending on the type and design, the nominal battery output voltage may vary (3.7, 4.2, or 7.4 V), while the standard USB bus voltage is 5 VDC. Obviously, in this case, a battery with a capacity of 2000 mAh with a nominal voltage of 3.7 V, even under ideal conditions, will not work for even an hour and a half when powering an external load connected via a USB bus and consuming a current of 1 A. In addition, the amount of electricity that can be stored Batteries having the same capacity but different voltage will vary.

Tip 2: look at the current strength, it affects the charging speed

id="sub1">

Another factor that affects the charging speed is the current strength. The more amps, the faster the charging speed. For phones and smartphones, this figure should be at least 1 ampere. Otherwise, the process itself will occur extremely slowly. To fully charge, it will take 3 or 4 times longer than from the mains.

For tablets, devices with a current of 3 A or more are preferable. The ideal option is 4 A.

Tip 3: trust, but check, because the declared capacity does not always coincide with the real one

id="sub2">

Another important point is the actual capacity of the Power Bank. The fact is that many manufacturers embellish the performance of their products. Of the 50 models of portable chargers that we tested over the past year, 46 had a capacity significantly less than stated. On average the difference was 25%.

For example, the manufacturer indicated that the external battery has a capacity of 10,000 mAh, but in reality it is 7,800 mAh. The difference is due to both the dishonesty of the developers and the improper storage of batteries during transportation and subsequent sale.

id="sub3">

The actual capacity is also affected by such an indicator as self-discharge.

On average, external batteries with a full charge are discharged by 5% within two weeks. This is worth considering if you do not use Power Bank for a long time. To activate electrolytic reactions, you should charge the device before use.

Keep in mind that the battery capacity will decrease over time. Our measurements show that with active use, a high-quality battery loses its capacity by 15% per year, the cheapest models - 35%.

To monitor the charge level, almost all Power Banks use LED indicators. And some external batteries are equipped with LED displays that show the exact state of charge in percentage.

Tip 5: choose a power bank with multiple USB ports to simultaneously charge your friends’ smartphones

id="sub4">

Some models of portable chargers have several USB ports for connecting two, three or even more mobile devices at once. This option is suitable for simultaneous recharging, for example, when you go on a trip with friends. It's comfortable. You can all charge your phones, smartphones and even tablets together.

You often ask us where you can be guaranteed to buy a high-quality external battery cheaply. We cannot give a definite answer. Of course, the reliability of purchasing from a large Russian online store or retail chain is higher, but the prices there are also higher. It is worth remembering that little-known Chinese sellers have a peculiarity: they can deceive. Their external batteries are much cheaper than their branded counterparts; they often indicate a capacity 2 or 3 times higher than the real one. Prices that are too low can be a trap. Although branded Power Banks in such stores can be fakes.

Compact

id="sub5">

If you need compactness, you can pay attention to ergonomic models, for example, Anker Astro E1. This battery will not take up much space in your bag or pocket.

Universal

id="sub6">

The ideal option would be batteries with a capacity of about 10,000 mAh. This is approximately three times more than the battery of a modern smartphone, which means that even taking into account the loss of energy during charging, it will be enough to fully restore the gadget’s charge several times. A high-quality example of such a power bank is the Anker PowerCore 10400 mAh model.

Another option for a high-quality external battery with universal functionality is the Aukey PB-N42 10,000 mAh.

Supports fast and wireless charging

id="sub7">

If universal options are not your option, then you should pay attention to models with additional functions. For example, a power bank with fast charging support will be able to charge compatible gadgets much faster than usual. If the battery is capable of delivering a consistently high current (about 2A), then even without fast charging support, your gadgets will charge stably and relatively quickly.

Among the ones we recommend is the Baseus Wireless Charge Power Bank 8000 mAh external battery. Its main feature is the presence of Qi wireless charging. That is, to charge a smartphone, you don’t need to connect a wire to it, just put it on an external battery and that’s it. Charging started. In addition to wireless charging with a current of 1A, the device supports a wired USB connection of two compatible devices, while the output current to the USB connectors is 2A.

A good option for iPhone is the Zikko PowerBag 6000 mAh external battery. The main difference from popular Xiaomi external batteries is MFI certification, which means the battery is compatible with all Apple devices. The device supports fast charging - the output current to the USB connectors is 2.4 A. In order to monitor the battery capacity, there are special LED indicators at the end. A nice bonus is that the smartphone is connected to the battery using the included Lightning cable.

With record capacity

id="sub8">

If you need a strategic boost of power, check out the HyperJuice 26,000mAh AC Battery Pack. This giant can quickly charge absolutely any device, including a tablet, other portable equipment and even a laptop. There are 2 USB output connectors here. One provides a maximum charging power of 3A at a voltage of 5W, and the other provides a current of 2.4A. A nice bonus is the ability to provide 220W power to any electrical appliances with a power consumption of up to 100W. You can connect a laptop, a flashlight, and even a blender to this battery.

The HyperJuice AC Battery Pack case is made of aluminum alloy, which perfectly protects the device from external mechanical influences.

We hope that our tips will help you buy a truly high-quality external battery and charge your phone, smartphone, laptop or e-reader without any problems.
