How does the Power Bank work?
AKB converts the voltage with the help of the converter Z, 6-> 5V. In this way, the output voltage is 5V, with a current of up to 0.8A. The battery can be charged via a network adapter, or from a computer via USB (voltage 5V).
As a basis for a power bank, modern manufacturers offer:
Lithium-ion batteries (Li-Ion)
|– large capacity (up to 3000 mAh); – output voltage З, 6-З, 7V; – up to 1000 charging cycles; – low weight and compactness; – low self-discharge coefficient; – no memory effect.||– does not like overheating, therefore, it must necessarily be equipped with overheating protection.|
Lithium-polymer batteries (Li-Pol)
|– flat or rectangular shape; – small weight; – high energy density per unit of volume; – no memory effect.||– more high cost; – protection against overheating and fire is required (additional scheme); – there is a likelihood of the battery coming out of the system at a very deep discharge.|
How to choose brand and which company power bank is best for mobile?
The type and size of the charger will depend on the capacity of the battery in milliampere-hours (mAh). Choose the capacity of the battery depending on the capacity of the battery and the gadget, for which you will buy an additional AKB. So, for example, for a smartphone – from 2500 mAh, for a tablet – from 5000 mAh.

A self-respecting manufacturer will not indicate false information in the instructions.
The power of the current is an important characteristic when choosing a power bank, since batteries with a higher power current (2A) will be charged faster. For some users, time is extremely important. The range of the current strength of the models of the power banks, presented on the market: 0.5-2A.
If you have to recharge a few girls from the power bank at once, pay attention to the number of USB ports, which the external battery is based on. In a portable cell with two ports (1A and 2A), port 1A is designed for telephones and small girls (for example, Bluetooth headphones), port 2A – for playing a player. However, modern devices have long been equipped with controllers that regulate the supply of charging energy and you can (almost) not be able to use it, use the 2-amp
For the convenience of users on many models of power banks, there are informational light indicators in the form of LED or LCD screens. The first option is less informative, with a high data error; often has the form of circular indicators. LCD screen: high-precision, provides the user with more information about the power bank, the charge rate of each connected device, the temperature
The weight of the device and its capacity (the number of internal power supply elements) must be connected. On the market there are fake models of power banks with an artificially sublime spring. In this case, these manufacturers indicate the maximum capacity of the battery. Therefore, if you want to understand which brand is good for power bank, keep in mind that the power bank weighs about 300 grams. Every 5000 mAh weighs about 100 grams.
It is recommended to buy only certified provinces, since the indifferent producers of the economy save money in order to protect the device, so that it can be quickly removed from the
When choosing a battery, carefully examine its casing (aluminum or plastic) for any damage.

Pox lovers need to know that there are solar cells with built-in solar batteries for powering solar energy.
