How to charge

If you want to charge the power bank , the included Micro cable should be plugged into the micro USB input part and the other part of USB cable should be inserted to a AC adapter connected to the wall socket or a computer USB port.(but the charging time will be longer than inserting to an adapter.)

What’s more , the power bank will light up to red while charging and the red light will turn off after being fully charged. We have probably calculated the charging period is 3-4 hours .

But if you want to charge your device ,you should plug the USB cable in to the USB output part and connect the other part to your device. And it is quite simple . you do not need to press a button . When the device indicates it is fully charged , we only need to unplug it from mobile power .
