What is better to buy an external battery for phone. How to choose a portable phone charger? How to choose a portable charger

The external battery (or as it is also called Power Bank) is a small portable device that allows you to recharge smartphones, telephones, tablets and other mobile equipment in almost the work, without using a power outlet and power adapter. Properly selected external battery Let you extend time autonomous work Your device is several times, which will significantly increase your mobility and will allow you to less worry about the charge of the battery and the probabilities remain without communication.

When choosing an external battery for a smartphone, first of all, you need to decide which container you need. In this question, you need to repel from the capacity of the battery of your smartphone and the mobility you want to receive. For example, if your device battery has a capacity of 3000 mAh and you want to extend the time of its autonomous work 3 times, then you need Power Bank to provide 2 full charges, that is, so that it is able to give a smartphone 6000 mAh.

In order for the external battery to charge your smartphone on 6000 mAh, its container must be much larger. The fact is that the battery cannot give all 100% of the energy that is stored in it. Energy will be spent on the conversion of voltage, heating, etc. In the amount, all these losses will be about 30-40%. Therefore, in order to get from an external battery of 6000 mAh, you need to choose a model, the capacity of which will be at least 8,000 mAh, and is better all 10,000 mAh.

After you have chosen the container of an external battery, you need to consider its dimensions and weight. Carefully examine the characteristics of the devices with the capacitance you need and decide whether you are ready to carry a device with such dimensions and weight or need to consider more compact devices. After all, if you get too cumbersome device, you will be inconvenient to use them. You will become more and more likely to leave him at home and eventually your mobility will not improve. In general, you should not chase the maximum capacity, it is important to catch a balance, otherwise the Power Bank will not be mobile.

Connectors on an external battery

Connectors - another important momentwhich must be taken into account when buying an external battery. Most models are equipped normal USB connector. This option is suitable for most smartphones, but in some cases a connector of another type may be required.

For example, now everything more smartphones The USB Type C connector is equipped with a cable from both sides of which the same USB Type C is used. In order to charge such a smartphone from the usual Power Bank you will need an adapter with USB to USB Type C. If you do not want to use adapters, it is worth it Search model with USB Type C connector. In this case, you can use a complete cable.

If you do not want to carry a cable with you, you can select a pan with a built-in cable. But, it should be borne in mind that such built-in cables are usually very short (up to 10 centimeters) because of what to use a smartphone when it is in charge will be inconvenient.

It is also necessary to take into account the number of connectors. Most external batteries are equipped with only one output connector. Therefore, if you need to charge several devices at once, then you need to choose a model with the corresponding number of outputs.

Smartphone charging speed from an external battery

Like a regular charging adapter, an external battery has such a characteristic as the output power of the current that is measured in amperes. The higher the output power of the current ,.

Budget Turn Banks usually give about 1 amper current. If you need to charge budget smartphone and push-button phone, then such a current is suitable. But, to charge more serious devices, you need to choose models that will be able to provide 2 or even 3 amps of current.

In order to determine which current current is needed precisely for your device, see what is indicated on the charger, which went bundled. On the charger should be approximately such a line "Output 5 V - 1 A". 1 A - this is the current of the current that needs your device. For the maximum fast charging, select an external battery that can provide the same or higher current strength. Do not fear if Power Bank can provide a large current strength than a regular charge. The charging process is managed by a smartphone, and it will not consume more current than he needs.

If your smartphone supports some kind of fast charging technology, such as Quick Charge 3.0 or Quick Charge 4.0, then you should look for an external battery with support for this technology. With the support of these technologies, the smartphone charging speed from the external battery will increase significantly.

In general, described above is enough to choose a suitable external battery for a smartphone. But, there are many more points that we would like to mention.

Choose models of famous brands. Power Bank is a fairly simple device, so many companies produce it. Many such companies disappear very quickly and do not follow the quality. To purchase a device that will respond to the stated characteristics, it is desirable to choose proven brands. For example, ASUS, SAMSUNG, Xiaomi, Huawei, Energizer.
Buy in reliable stores. External batteries are often forged, so do not save and buy turns on Aliexpress or somewhere on the market. It is better to choose a large and proven store that will definitely not trade "Palented" product.

Everyone is called this subject in different ways, but they miss it equally strongly when the battery on zero, and there is no sockets. Arsenal Gadgets is now not limited to a smartphone, it is often attached to him. wireless headphones, "Smart" watches, fitness bracelets, Bluetooth speakers ... their owners are the question of how to feed all this nails, it becomes particularly acute. We tell how external batteries differ from each other, how to choose the right right to you and how they correctly use it.

How much do your devices consume?

You need to start with an answer to this question: After all, a lover climber is to shoot on the Gopro-camera and mount the video on the tablet in mountain campaigns need larger volume Energy than an office manager floating with a player in the pool. For clarity, we give the average battery capacity in some types of devices:

action Camera: 900 mAh;

wireless headphones: 150 mAh;

music player: 1800 mAh;

wireless column: 3000 mAh;

smartphone: 3000 mAh.

Taking the basis of approximately such numbers, it is enough to remember which devices you use most often and plan to charge; Get something in this spirit: 1800 + 150 + 3000 \u003d 4050 mAh.

At first glance, here is the container that is needed in a wireless charging to replenish the battery of all devices. In fact, this number is advisable to multiply another percent on 20 to compensate for the heating losses, the effect of low temperatures outside and other factors. It turns out 5000 mAh.

The second characteristic that needs to be paid attention is the output voltage and current power. It is not necessary to remember physics, because most of the charges of the output current 1 A or 2.4 A. The larger the current (a) is better. After all, smart portable technique can limit the current to the desired meaning, But get more - no.

In general, portable chargers are divided into five conditional categories.

Pocket assistants

How to calculate: Capacity up to 3000 mAh

Such charging is a chic supplement of the car of the car, bags and a backpack, as well as the inner pocket of the jacket at the skier. They are doing, but they will help when they need to add charges on a smartphone or fow the action chamber. You can choose a compact charging in design sympathies, and it is not necessary to study the characteristics of the output current at all: often the real output current is 1 A, which means that the cost of charging will be about three hours.

Signature RedLine R-2600 by 2600 mAh with current force 1 A

Power Bank can be safely charged to lay it just in case. Self-discharge of such devices is very slow, for the year your portable battery will only sit down percent for 10-15.

Workers for every day

How to calculate: Capacity about 5000 mAh

These casual charges most often meet in passersby in hand and in the cabin car, where it is possible to feed the battery from the cigarette lighter. Comfortable, compact and effective assistants of the active owners of smartphones, devoid of opportunities to change the battery in unbeatable devices. And at the same time lovers of short travel and travel with their own move. You should choose such charging on the output strength of the current from 2.1 A, and also give preference - the coolest battery elements resemble thick batteries.

Food for a large company

How to calculate: Capacity from 8,000 to 12,000 mAh

If you pay for gadgetoman and shopping in the store, not even a smartphone, and the clock, the collection of technicians will be able to feed charging more powerful. In this capacitive group, they have a strong output current, and even accelerated charging technologies, therefore the design and number of ports for simultaneous feeding becomes the determining factor when choosing. Note: Often the second USB output is weaker than the first, so we recommend clarifying this parameter in characteristics.

TTEC POWERSLIM for 10,000 mAh with current 2.1 a

The accelerated charging technology significantly reduces the time to the cherished 100 percent on the smartphone battery. An hour, a maximum of one and a half - and the phone is fully ready for work. However, pay attention to what the accelerated charging technology supports your gadget. QuickCharge, Supercharge, Adaptive Fast Charging - all this different typeswho are not combined with each other. Thus, the smartphone can accelerately charge the Supercharge (if it is Huawei P10), and Power Bank support Quickcharge. In this case, the gadget will turn out, but the charging time will be ordinary.

Pocket power station

How to calculate: by capacity 15 000-20 000 mAh

Many of these are ready to charge even MacBook 12 and other laptop models with charging connector USB Type-C. And at the same time and distribute the energy at once to several devices without power drops on one of the USB outputs. These charge stations are good all, but their size and weight are not hidden. Such a demise limits their scope of application, but if you need confidence in the work of the whole technique for a few days ahead, it is barely compared to them by the effectiveness of the return.

Wireless portable charging

Attach smartphone and see

More and more new smartphones are equipped with wireless charging modules of the Qi standard and analogs - for example, Samsung Galaxy S7, S8, iPhone 8, X. It is enough to put such smartphones to wireless charging, and the battery feeding will start automatically. No wires and confusion, because the basis of technology is taken magnetic induction. Most of the smartphones supporting wireless charging work just according to QI standard, and more recently began to appear and suitable for them are fast. When choosing such charging, it is better to slightly increasing the reserve by the capacity to compensate for the energy loss to such a spectacular transmission process. By the way, such chargers themselves are able to charge from stationary sites.

Instead of output

To deal with the manifold of portable charging is easy if you match the closing model by parameters and know what kind of capacity it will be necessary. It is impractical to take charging with a margin, because it will affect the convenience of wearing with you, without bringing special benefits. Deciding with appearance and capacity, make sure the presence of the necessary bonuses - wireless or fast charging, and then you can safely buy a convenient, practical and appropriate device.

Contrary to the mind of the opinion of Power Bank does not spoil the battery of the smartphone. Just feeling that salvation is always at hand, the owners of gadgets begin to more actively use the device, it is more often charged and thereby increasing the number of charging cycles, which for each battery is limited.

This is all physics, I am not strong in it, but the fact is a fact. First of all, when buying pay attention to the container. We calculate 60% from it and we get a precise number of charge without loss, which will go to the device itself.

Do not be kept when buying on low price and a large number of Miliamper clock. Such gadgets are quite mediocre. Remember, a good turn Bank from 20,000 mAh should not cost less than 2000-2500 thousand rubles.

Tok Power

It is from the strength of the current depends, how much time is wireless charger Will charge your gadget. Usually, smartphones for charging need 1 amp, and tablets 2.

Weight and size

Why is this important criterion when choosing? Everything is simple, portable charging must be:

compact
not too heavy
and have a convenient design (the thinner, the better)

After all, why do you buy it? To take with me hike, on a trip, on a picnic, to the country and so on. In general, to the place where there is no possibility to charge from the outlet.

Of course, Power Bank must be small. Who wants to carry in their bag stone weighing a few hundred grams? But here two sides of the coin. The smaller the device you acquire, the smaller the container it has.

You need to look for a golden middle. Moreover, manufacturers take into account such parameters and make it possible to combine high performance and compactness in one device.

Number of USB connectors

Imagine that you went to a tourist campaign with your friend. So you sat down to have a snack, relax, go to the social. Networks or look a video clip ... But it's not enough, as I discharged the batteries on your smartphones discharged. And then you remember that you have a portable battery!

You with a satisfied view take it out of the bag and put your gadget for recharging. Your friend, of course feels deprived. Well, right, it was necessary to think in advance and buy yourself such a device ...

Of course, you do not do a good man, but simply share with another second USB port. No wonder many models are equipped with them. By the way, the two manufacturers are not limited. Often you can meet more.

View of the battery

The battery itself in the device may be ( click to open description):

lithium-ionic

By appearance Similar to conventional finger batteries and is the most optimal price-quality. The lithium-ion battery is enough for about 1000 charges, then the power begins to fall and the mah disappear.

lithium polymer

Can take a more flat form. Lithium-polymer battery It will last much longer (about 5,000 charges), it will be higher than it. Such batteries in the pancakes are less common.

Removable battery

Some devices have a function of removable batteries. That is, batteries that change as needed. So you acquire yourself the housing portable deviceAnd the battery can always be replaced by itself.

Plus such models are that they will serve much longer. Over time, any Power Bank wear out and charge it becomes less and less. In the case of a similar device, you can always replace the battery for a new one and, voila, you have a new device.

But there are also disadvantages. Such a hard pot is working on a small strength of the current, and this increases the charge time.

Availability of indicator

In addition, the light indicator can be found on the device. Which indicates how much charge is still left. You can also find a device in which there is a display.

Buyers say that seeing the charge in percent on the display is much more convenient than the light bulbs. But there is a minus. The screen also consumes some part of the energy that could go into the gadget.

Automatic shutdown

One of the important functions of Power Bank is automatic shutdown. It protects against short circuit, as well as from sharp energy jumps that can damage the charged devices.

In addition, such a function prevents in vain energy consumption. For example, you can put gadgets for charging at night and not worry about that after a while you will need to wake up and disable the battery.

Additional features and accessories

For example, for turcomers, you can buy a Power Bank with a flashlight and hand warming. Some models are equipped with even connecting to Wi-Fi and the input for the flash memory storage. In short, that just do not come up and as soon as the device does not decorate.

You can also choose an adapter for its charging and a protective case to your external battery. Mostly silicone covers, they will protect the device from dirt, dust and possible hit water. The adapter will help to charge chambers 2 2 times faster.

What company choose an external battery?

Many device data firms. Among them, there are both popular brands and not known to anyone. Basically, all devices are manufactured in China. For this reason, I see the point of ordering the device there.

Firstly, You do not overpay your extra money
Secondly, Delivery to Russia and the CIS are mostly free

At the exit, we get a device from the same China, but much cheaper than in the city store. Of course there is a minus, because about a month will have to wait for the parcel. But, for example, it doesn't scare me at all. In any case, in terms of money remain in the plus. And if, the purchase will become even more profitable.

I picked up a few models of Pole Bank with Chinese shopping areassuch as Gearbest and Aliexpress. Also allocate a couple of well-known firms whose devices are most popular worldwide. Here are the brands that we will consider in this article:

Samsung - Korean firm famous world

A year ago I did not understand anything at all in the gadgets and decided to buy myself a portable battery. Then no one suggested me how to choose a pan for a smartphone. I spent 500 rubles per battery, the power of which, as was stated 8000 mAh. But in fact, Miliamper clocks turned out only 3000.

Yes, it was my unsuccessful purchase ... My iPhone 6S Never charge this battery completely. Only 60%. What I write it all. If you want to buy a really highly productive device, then less than 1000, and it is not worth spending 1500 rubles. Otherwise, you will have to pay twice and buy a second device with a greater power, as I had to make me.

I hope this article was informative and helped answer the question of how to choose a portable charger for the phone, tablet and other gadgets.

Types of batteries for phone

After analyzing the history of the AKB development, it turned out that there is only 4-type batteries for the phone.

Nickel-cadmium batteries (NI-CD)

This type of batteries was made in the distant 1899. Due to multiple deficiencies, it was not prevalent. Although they are strong enough and durable. Can withstand drops of high and low temperatures. In addition, it is withstanding a lot of multiple charging.

The main disadvantage overlapping all the advantages is their toxicity. Cadmium is a poisonous substance. Besides this type The battery for the phone has low energy intensity. Production costs are highly high. And the periodically manifest memory effect is forced to do frequent. This is not very convenient.

Nickel-metal hydride batteries (Ni-MH)

These nutrition elements are made on the basis of nickel. The main positive property is good capacity and low production cost. Previously, a similar type of battery was used in large phones of a budget type with limited functionality.

Their main minus is the effect of memory. You put for charging at a 30% battery indicator and then the phone turns off how it comes to this figure. Such a property is less pronounced than the above described type. Also such batteries are charged for a long time.

Lithium-ion batteries (Li-Ion)

To date, this type is the most relevant! Their main advantage over competitors:

Compact dimensions.
Big.
A small self-discharge.
No memory effect.
Show stable performance.

Similar batteries for mobile phones Work stably and long.

Of negative Parties It can be noted a high cost in contrast to nickel batteries. Poor tolerate cold. For minus 20 0 C is the risk of electrolyte leakage. In the discharged state, these power sources should not hold. Service life can be reduced. Substitute to wear in independence use them or not.

Lithium polymer batteries (Li-POL)

This removable battery for the smartphone is made using lithium salts and polymer electrolyte. This approach allows you to create a charging battery for the phone of various shapes. Subtlety and plasticity are the main chip of these batteries.

Pros:

High energy intensity, about the same as lithium-ion internal batteries for phones.
The cost is significantly lower than those described.
A large number of charging / discharge cycles.

Minuses:

Unstable work at low temperatures.
It is harmful to a strong recharge and deep discharge. To prevent a built-in voltage controller. And this affects the cost of the product.

Reinforced batteries for phones

These models are called another powerful battery with elevated. Unlike they have compact dimensions. Their sizes coincide with the native battery device. Most often, the devices are Chinese or Japanese production.

The main energy intensity starts from 2450 mAh and ends 5500 mAh. Such characteristics of the battery allow you to increase the work of the smartphone at times! And reveal its opportunities to full.

The main characteristics of batteries for phones

The data in the table will help you select the desired batteries for cell phones.

The main advantages of Power Bank for phone

Good durable case.
Large container.
The ability to repeatedly recharge the portable battery for your phone.

How to choose Power Bank for phone?
