Electricity-Charged Power Banks: Power banks have an input socket for receiving power. Just connect it with a USB cable in its socket and connect the other part of cable in any charging switch socket or connect with your laptop or computer.

Power banks take time in charging according to their capacity. For example a power bank with 1500mAh rated power capacity will take time in charging same as your smart phones charging time. For larger power banks charging time will be increased according to its capacity.
Power banks have a light indicator to show their battery power. Some have five lights to show the battery. The charging is according to the number of lights. Some have a small LED screen which shows the percentage of battery.
Some digital power banks have a special option of the automatically power cut to prevent over charging, and everyone knows that overcharging will destroy the battery. The advantage of these power banks is if you forget to disconnect the charger while charging the power bank. It will automatically stop charging when a battery is full.
Some power banks don’t support high capacity chargers like 2A chargers.
