Store Without Limits: Integrated USB-C Cable for Versatile Charging

Forget about cable clutter! With our integrated USB-C cable, you can not only charge your devices with up to 100 W but also recharge the power bank itself with up to 60 W. Never be without power again, no matter where you are.

Super Fast: 165 W Total Power for Ultra-Fast Charging

Experience lightning-fast charging for all your devices with a total power output of 165 W. Charge laptops, tablets, and smartphones in no time and save valuable minutes. For optimal charging speed, we recommend a separately available 65 W power adapter. The power bank is fully charged in about 1 hour and 45 minutes.

High Capacity and Versatility: Three Ports for Maximum Flexibility

With USB-C, an integrated USB-C cable, and USB-A ports, our power bank offers maximum versatility. Perfect for travel and everyday use – charge multiple devices simultaneously.

Real-Time Information at a Glance

The intelligent LCD display shows you the battery level, active inputs and outputs, as well as the fast charging function via a lightning symbol – providing complete transparency while charging. This way, you always maintain control over the energy flow and remaining capacity.
