Since mobile devices have won the market, users have increasingly begun to attach importance to the battery life of the device, and the developers, in turn, have begun to work diligently to increase the battery capacity. Despite all this, the modern rhythm of life dictates its own rules and it often happens that there is no time for recharging. Fortunately, manufacturers of various gadgets and accessories quickly got the idea to release an external battery (Power Bank), which you can take with you and recharge a smartphone or tablet from it, if the need arose. Not all users have yet discovered the usefulness of this device, so it doesn’t hurt to tell more about it. In this article we will understand how the external battery works and what it is all about. So, let's begin. Go!

So that the device does not let you down at the right moment, it is important to follow the rules of its operation.

Arrange any Power Bank as follows: several batteries are soldered to a small controller board, to which connectors for charging gadgets and the battery itself are connected. The reliability of the whole structure depends mainly on the use of high-quality components, as well as compliance with the technological process during production.

The principle of operation of any Power Bank is very simple. First you need to charge it, and then, if necessary, connect the phone itself to it. Depending on the model of the external battery, it may have an on / off button. Most Power Banks begin charging the plug-in device automatically, but if this does not happen, then it must first be turned on.

Also, the case of an external battery has a special indicator showing the number of charges. There are usually four of them. That is, after four recharges from Power Bank, you will need to charge the external battery itself.

The indicator helps to control the charge level in an external battery.

External batteries of good quality are distinguished by the fact that they have a special indicator that signals the start of the charging process, and when it is completed it turns off. This is a very important point, because if this does not happen and the phone continues to charge, it can negatively affect the work of the battery of the smartphone itself. Therefore, always buy only high-quality external batteries, since any "savings" can subsequently go sideways.

There are a number of rules that will help maximize the life of an external battery:

1. Watch the temperature. Remember once and for all - for any battery there is no worse enemy than a high or low temperature. In no case do not leave the battery in the cold or under the sun, as this will greatly reduce its capacity.
2. No Chinese charge. Charge the Power Bank with only tested, high-quality chargers. "Saving" on buying a good charge, you just spend more money repairing an external battery or smartphone.
3. Bought? So use. If you have already purchased an external battery - use it, you should not keep it for some special occasion, like a long trip. Remember - any battery likes to work. Without operation, the battery loses its capacity and in a couple of weeks without exploitation it will be much less confused than it was originally.
4. Do not be afraid to operate the Power Bank in full. Any decent manufacturer guarantees at least 500 full charging cycles. This is enough for you for more than 5 years. So use bolder.

Also be sure to pay attention to the current strength when charging before buying an external battery. The standard is 1 Ampere, but tablets require 1.5–2 amps. Consider this circumstance if you are going to charge the tablet.

Choosing an external battery, rely on the characteristics of your gadget, whether it be a tablet or phone

Another important point is the capacity. Be sure to take into account your needs when choosing, if you are not a fan of long trips to the mountains, Power Bank with a huge capacity is simply useless. Capacity 4-6 thousand milliamps for the average user will be more than enough. So approach the purchase wisely and do not throw away money in vain.

In general, from all of the above, you can make an input that an external battery is a very useful (practically necessary in modern reality) thing that, if used reasonably, will serve you for a very long time.
