GoGEN PB300001B powerbank, 30000 mAh, USB-C PD 20 W, LCD, nero

GoGEN PB300001B is a black power bank with a 30000 mAh lithium-polymer battery and a numeric LCD charge indicator. It provides one USB-C output and two USB-A outputs for charging compatible mobile devices. USB-C Power Delivery reaches up to 20 W; the power negotiated depends on the connected device and cable.

The manual specifies USB-C output profiles of 5 V/3 A, 9 V/2.2 A and 12 V/1.67 A. Each USB-A output is specified at 5 V/3 A, 9 V/2 A or 12 V/1.5 A. These are individual-port profiles, not a promise of full power from all ports at once. The power bank can be recharged through its Micro-USB or USB-C input at 5 V/2 A or 9 V/2 A.

The display shows the remaining charge as a percentage. Charging starts automatically when a compatible device is connected; the button can reactivate the unit. Overcharge protection is included. A compatible charging cable and USB power supply are required for recharging. USB-C connector compatibility alone does not establish suitability for a laptop requiring a higher-power supply.
