What to look for when buying a Power Bank
We can also come across many variations in terms of power banks, or external batteries. You can play with colors, patterns and shapes. Popular among girls is the type that is small, does not take up much space and can easily carry this accessory with them in their bag. For those who like to hike or do not have access to resources for a longer period of time, we recommend the higher-power 10 or even 20 thousand mAh power banks.
The most important thing in the case of power banks is the size of the battery cell in it, expressed in mAh. The battery of an average device is roughly 4000mAh. From there, you can find out how many times you can charge your device on the given external battery if you divide the mHa number of the power bank by the phone number. In general, we recommend that you choose a type that can definitely charge your phone 2x (8000-10000 mAh).
