Connect a USB-C charging cable (Type-C to Type-C or Type-A to Type-C) to the power bank's USB-C port and the other end to a compatible power adapter. Using a PD18W Type-C charger can achieve a faster full charge in approximately 4 hours.
The power bank supports pass-through charging, allowing you to charge your devices while the power bank itself is being recharged.
