External batteries seem to have recently appeared on the market, but today they are owned by a lot of users. No wonder: a small “box” allows you to charge a discharged smartphone, phone, tablet or other gadget away from home. In addition, the Power Bank fits easily into any bag, and there are models that can even be carried in your pocket!

But today we are not talking about size. Many users are interested in how to charge external battery. In fact, everything is very simple, although there are nuances that are worth knowing.

Charging Options

First, let's look at charging options.

First and perhaps the most popular - from a computer or laptop via a USB port. Connect the Power Bank with one side of the cable, insert it into the other USB port, the device starts charging immediately.

True, charging is not as fast as we would like - it's all about the features of USB technology.

Second option- charging from the network. Have you noticed that external batteries are sold without a charger? It is understood that the user will charge the gadget either from the USB port of the computer, or from the charger that comes with the smartphone or tablet. Note that charging from the network is much faster than from USB.

Third option can be called exotic - charging from the sun's rays. AT this case it is assumed that you are using a special Power Bank on solar panels, which can actually be charged with the energy of the sun. Here's what it looks like:

Fourth option- charge the Power Bank from your phone or smartphone. Think this is a joke? Now appeared mobile gadgets, which can act as a kind of external battery, which means that they can also be used to charge the Power Bank. Like this.

How long does an external battery charge?

It depends on the capacity of the external battery, as well as on the charging method. The fastest way to charge the gadget is from the mains charger. The average charging time for a 5000 mAh battery from a 1A charger is 5 hours. Accordingly, if the battery has a capacity of 10,000 mAh, charging will last about 10 hours - from 0 to 100 percent.

If you charge the Power Bank in other ways, the charging time can seriously increase - even several times. Solar batteries take the longest to charge from the sun.

Power Bank Charge Features

• In order for the external battery to gain full capacity, it must be charged to 100% at least 3-4 times.

• It is believed that Li-Ion batteries do not have the so-called "memory effect", which we are talking about. But there are people who think otherwise, so they recommend charging the Power Bank always up to 100% in order to maintain maximum capacity.

• As for discharging, it is not recommended to discharge the external battery to 0% - no more than 10-20%, after which it must be charged. You can find this out using the display level. If there is none, try to do it by eye with LED indication.

For example, the Xiaomi Power Bank LED indication:

• It is believed that if you discharge the Power Bank "to zero" every 2-3 months, this will allow it to "calibrate".

• Do not charge the Power Bank in direct sunlight (except for external batteries designed for solar charging).

• Always use only original cables and chargers.

It's no secret that high quality external batteries power bank, buy which are available at an affordable price in , are becoming a sought-after addition to gadgets.

With each new generation of devices, the complexity increases internal batteries, as devices are supplied with more and more new features. But with prolonged use of a loved one smartphone or tablet, the gadget is prone to rapid discharge.

The idea of ​​extending the operation of the device using external battery far from new, because earlier cases for gadgets or special modules that were connected to mobile phone. Such a battery, as a rule, was not enough for one full charge of the device.

On the eve of the New Yearpower bankwill be a great gift for those who spend a lot of time outside the walls of the house and constantly need to be in touch.

Rules for using external batteries Power Bank

A modern external battery is several Li-ion batteries which are installed in a plastic or metal box. This device is capable of storing and transferring charge to your gadgets.

The terms of use are as follows:

• for recharging itself external battery connect it to a power source (socket, tablet, laptop) using the cable that is sold in the kit. After connecting, make sure that the charge indicator works. When the device shows 100% charge, unplug it from the power source. Depending on the capacity of the battery, the time for charging it is determined. Remember that the cable for recharging the battery is different for each model;
• To recharge your gadget (smartphone, tablet), use a USB or microUSB cable. To do this, connect a smartphone from one end, an external battery from the other, press the button (if any) on the battery and confirm the charging of the gadget. The indicator on the battery will show you the level of remaining charge. In many models of external batteries there are no buttons for confirming the charge; after connecting the device, recharging turns on automatically;
• When your smartphone or tablet is charged to the required level, disconnect the cable from the external battery and from the gadget. Some chargers have a built-in function automatic shutdown when your device's battery is fully charged.

So finally you have mobile Charger(power bank).

Congratulations! Buy Power Bank in Ukraine- very correct decision!

(If you are only thinking about such a purchase - in which you will order)

Of course, you would like the charger to last as long as possible and please your gadgets with eternal "online". To do this, you need to know some features of Li-Ion batteries and follow a few simple rules usage:

1. After purchasing an external battery, fully charge it immediately.

The ideal charging process (both PowerBank and the battery of your phone / tablet) includes the so-called "drip" charging - charging the gadget for some time after the indicators show that the device is 100% charged, while the charge continues for a very weak current.

Designed for smartphones and tablets special applications, recognizing "drip" charging:

http://bit.ly/battery-doc - for Android

http://bit.ly/battery-doc2 - for Apple (the application is no longer available in the AppStore)

Previously, in order to find out when the “drip” charging was over, you needed special measuring equipment (ammeter, voltmeter - tester). A rather narrow circle of radio amateurs knows how all this equipment works, and not everyone wants to delve into all these details (even for the sake of increasing battery life).

That is why they have become such a joyful and saving novelty for everyone.

With this little device, you can see not only the voltage and current, but also the amount of Ah (ampere per hour - the unit of capacity for all batteries) that has passed through USB tester. Therefore, you will always know what condition the battery of your phone, tablet is in or, since we are talking about Power Bank, power bank capacity.

()

Usually power bank charging goes with a current of 1-1.5A. The closer to the end of charging, the lower the number of amperes. "Drip" charging is 0.1-0.05A. In order for your battery to have maximum capacity for as long as possible, wait for the "drip" charging to finish. As soon as your USB tester will show 0.00A - charging is fully completed and the device can be disconnected from the network.

2. In order for your Power Bank to gain its maximum capacity, you need to make 2-3 full charge / discharge cycles.

Also, if in the future the Power Bank began to discharge faster than usual, it is worth repeating this cycle of 2-3 repetitions and thereby rewriting the battery statistics.

3. ALWAYS charge Li-Ion batteries up to 100%!

Try to never stop charging ahead of time - only after the battery is 100% charged. Yes, many will say that "modern Li-Ion batteries do not have a" memory effect ". Yes, manufacturers also claim this. But, based on our practice and experience, this is not entirely true: in Li-Ion batteries this effect is much less, but still present (this also applies to phones and any other gadgets).

4. Do not discharge the PowerBank completely (to 0%)

Modern Li-Ion batteries that come with mobile batteries do not require it. Moreover, their constant discharge to 0% reduces the service life. Charge the Power Bank when it still has 10-20% charge.

In external chargers with a percentage indication of the discharge / charge level, it is very easy to find out, in devices with LED indication - you have to do it “by eye”.

(devices with % indication you can find )

5. This point contradicts the previous one, but nevertheless it is also very important: from time to time completely discharge the battery (every 1-3 months).

This allows you to reset the charge limits (upper and lower - to calibrate the Power Bank).

6. If you do not plan to use the external battery for a long time, discharge it by about half.

Storing a fully charged (as well as a fully discharged) battery is very harmful to it and will significantly shorten its life.

7. Use only original mains chargers or those that have the required characteristics (if power bank recommend charging with a current of 2A, then use a charger that gives 2A).

Network adapters should be mentioned separately: they are in real trouble. Finding one that produces the declared current is a very difficult task. Even buying an expensive adapter in company store, very often you will get the output not 1A, but 0.5A. And this is half the trouble (just your phone / tablet will charge 2-4 times longer). Much worse, if in fact it produces much more current and does not smooth out significant voltage surges - this can already greatly reduce the battery life of your gadget, and sometimes even lead to its failure.

The problem is that if you don't have a USB tester, there's no way to know if your charging is normal or not. The phone is charging - everything seems to be in order. This is exactly what unscrupulous manufacturers and sellers are counting on (the same can be said about cables - even if charging gives out 1A, a poor-quality cable can lose up to 80% of the current, and you, again, will not know about it without a tester).

That is why we almost always recommend our customers to order a USB tester immediately. This purchase will pay for it more than once! Here you will find various : more expensive and cheaper, more and less informative. But whichever you choose, it will be one of your most useful and smart purchases!

Speaking of network chargers:

for a long time we did not sell them at all precisely because of this: we could not find a reliable supplier who had good and (very importantly) constant quality. However, buyers constantly asked, and we did not stop looking. After many test purchases, I managed to find it. Now you will find many high quality original chargers . Among them -

8. Avoid overheating PowerBank - both during charging and from external factors (heating battery, direct sunlight, etc.)

If you do not neglect these tips, your Powerbank (as well as any other device) will serve you for a long time and properly.

Do you want to eliminate the risk of force majeure associated with the sudden discharge of a smartphone, tablet or laptop away from sockets? We recommend to buy an external battery ! This is an incredibly practical and useful thing that allows you to recharge your gadget's battery away from outlets. Of course, to restore the battery of the device, the VZU must be pre-charged. This is quite easy to do, but you should know how to charge external batteries correctly to maximize their service life.

How to charge external batteries for phones: top 5 tips

Fully charge the portable battery after purchase, referring to the indicators. According to experts, it is recommended to additionally use the process of "drip charging" of the OCD with a weak current. This means that the gadget must be connected to the power source for some time after the indicators show 100%. This has a beneficial effect on the performance of the VZU. Before, how to charge Xiaomi external batteries, you can use a special device - a USB tester with a built-in voltmeter and ammeter. As soon as the gadget shows a value of 0.00A, charging is completely completed and the VZU can be disconnected from the network.

It is believed that in order for an external battery to gain maximum capacity, it should be fully charged and discharged 3-4 times. Thus, it will turn out to rewrite the statistics of the VZU and use it on the verge of possibilities. External battery for tablet or a Li-Ion phone should always be charged at 100%. Try not to interrupt the recovery of the VSD from the network until the indicators light up. In turn, talking about how to charge external power bank batteries, it should be noted that the models of this type it is better not to discharge to zero, as this significantly reduces their service life. Try to connect the gadget to the outlet when it still has 15-25% charge. Please note that VCDs with a percentage charge indication allow you to clearly determine this indicator, and in the case of an LED indication, you will have to do everything “by eye”.

How to charge external batteries from the network?

To do this, just use the standard bundled cable or connect any compatible one. To start the charging process, you need to plug the connector into the port of the external battery and connect it to the network alternating current. LED indicators will allow you to control the level of replenishment of the battery. However, it must be taken into account that they can often give inaccurate results, especially if the OVC is used for more than 1 year. Alternative option-batteries with digital indicators. They are much clearer and clearer, but their cost is 18-25% higher than that of analogues. Charging external battery for phone from the mains, try to avoid power surges. Most modern models have protection against overheating and burnout. It must be taken into account that

Without Power Bank, we are already without hands - when we are not at home, but we need to quickly recharge our smartphone or other device, it comes to the rescue. It fits easily into a bag and is not heavy at all. But it also needs to be recharged from time to time. How to do it right?

How to properly charge Power Bank, including for the first time

Let's talk about the rules for charging and in general about the ways by which you can power an external "battery".

What to do immediately after buying a Power Bank

In order for the external battery to please you with its work for a long time, immediately after purchase, do the following:

Instructions for proper charging

Before you start using your Power Bank, read the instruction manual that comes with it, and also follow the recommendations that will be discussed later.

"Power Bank" can be charged in three main ways: from a laptop or desktop PC via a USB cable, from an outlet using network adapter and from the cigarette lighter in the car. The second method is the fastest, as the socket can provide sufficient charging current. You may not find this adapter in the battery kit, as it is assumed that you can use the adapter that comes with the phone. However, these adapters usually only supply 1A current. It is recommended in this case to buy an adapter for 2–2.4A and 5V, or use an adapter to charge, say, a tablet.

The power adapter must supply current 2 - 2.4A - no more

The Power Bank is connected to the network in the same way as a phone: the USB plug of the cable is inserted into the adapter, the micro-USB is connected to the "battery". Plug the adapter into a socket. Usually, you do not need to press anything to start the adapter - the battery itself recognizes the flow of energy and starts charging.

How long do you need to keep the battery on charge? A small battery with a volume of 4000 - 5000 mAh will last about 4 - 6 hours. The battery can safely be left to charge overnight without fear that it might overcharge. In the "batteries" they put special controllers that turn off the charging completely as soon as the battery is filled with energy. That is, you do not need to monitor the progress of the charge.

How to understand that Power Bank is charged

When the last light stops flashing or when 100% appears on the screen, this will mean that the bank is charged. Many "batteries" turn off themselves after a full charge, you just have to get the plug from the outlet and USB cable from "accum".

Instead of a display, there may be bulbs that show the battery level.

If you just bought the device, charge it up to 100%, and then, as you work with it, spend 2-3 full charge-discharge cycles. You do not need to monitor the charging process, you can safely leave the battery connected to the network at night. When the battery is full, it will programmatically disconnect from the network (all indicators will turn off). Use a power adapter with a current of no more than 2 - 2.4A for charging.
