These powerbanks are pretty handy but they are not compatible with the majority of modern-day devices.
How to charge a Powerbank
Powerbanks come with dedicated input sockets. Those are the sockets you will be using to connect its power cable and plug your device to a wall outlet.

Powerbanks generally have indicators as well so you know its power level. There are many units that boast efficiency ratings to up to 90%. However, it generally finishes up with just an 80% efficiency rate in general.
Choose the proper Powerbank
There are many things to consider when it comes to choosing the proper powerbank. One is your usage. When it comes to a portable power source, the most crucial feature you would search for is its capacity. This is often measured in mAH. there's no exact number of how many times your powerbank can charge your device. However, the rule of thumb here is that it should have more mAH rating for more capacity.
If you go for a solar powerbank, that will take some time to be recharged. However, such a device becomes priceless in the absence of regular power outlets (such as when you are camping in the woods for a couple of days).
