Article in English: In general, wall sockets will charge a power bank faster than a computer or laptop. Stick to charging your power bank through the wall unless you only have a laptop or computer available. The power bank should come with a charging cable with a USB port and a wall adapter. Avoid using a different charging cable that was not designed for the power bank. Make sure not to leave your power bank plugged in for too long. Charging the bank for hours on end can cause its battery life to decrease. Only charge your power bank as long as necessary for the LED lights to stop blinking. While your power bank is charging, plug in any electronic devices you typically charge with your power bank into a wall socket. Charging devices eats up a power bank's battery. If you charge your electronic devices at the same time, you won't have to use the power bank as quickly after it charges. This will increase its battery life.
