To recharge this battery, please use the USB-C  port. You will need a USB-C to USB-C cable and a USB-C wall charger to recharge PowerCore.

We have included one USB-C to USB-C cable in this battery pack to recharge the battery. 

If you use a USB-C to USB-C cable to recharge the battery, you will need a 30W wall charger with a USB-C port. The time to recharge when using a  30W wall charger and  USB-C to USB-C cable is about 4 hours.

If you still have problems with how to recharge the Anker 535 Power Bank (PowerCore 20K), please contact us for further assistance.
