First thing first, understand your gadget and the capacity of Power Bank!
This is most important, you have to know for sure the battery capacity of your gadget. Do not let yourself buy Power bank that has less power than battery power of your gadgets.blogspot.in
For example if your phone battery is 1500mAh and is 0% now, a powerbank with 2200mAh can charge your phone 1 time.a-mobile.com.my
If your phone battery is 3000mAh and is 0% now, a powerbank with 2200mAh will not be able to charge your phone to full because the phone battery capacity is higher than the powerbank.blogspot.in
If you require a powerbank that is able to charge your phone several times, you need a powerbank with higher capacity.a-mobile.com.my
Secondly, Power Banks do not act only as a means of charging the battery. Therefore, choose the Power Bank which has the following features:
A) Protection of short circuit. As we know fires are often caused by a short circuit. Choose a bank that features a power cut power when a short circuit occurs.blogspot.in
B) Protection of overcharge. You need the Power bank that can automatically cut off the electricity when charging the battery is full, because overcharge will certainly shorten the life of the bank.a-mobile.com.my
Also, make sure the battery in the Power Bank is genuine and not refurbish!
