Rated Capacity and Actual Capacity:
Power Bank's capacity is measured in mAh or the amount of energy stored in a battery. actual capacity will be 60% of rated capacity. If we buy 10, 000 mAh power bank, we only get 6, 000 mAh. You should keep it mind while buying a power bank.
Charging:
We can calculate charging time by using simple formula. The formula is Power bank capacity /(input current multiplied with 80 % efficiency). We can charge power banks in night.
Basic Rules:
Charge power bank with correct input voltage. High voltage can damage your battery.
Don't charge the power bank and charge the electronic device same time.
Don't attempt to open power bank.
Output Power:
Most of the phones accept 1 Ampere charge and tablets accept 2.1 Ampere charge. You must understand about it and buy power bank according to it.
Quality:
Now power banks are available for low prices. In my opinion, we must buy some high cost power banks for our safety. We must go for branded power banks.
