Product details

The smallest 3-in-1 power bank that is always charged!

Always charged. How is that possible?
The magnetic charging dock from TAU can easily be attached to a piece of furniture or the wall to effortlessly charge your power bank. When you come home, simply hang your keys on the magnetic charging dock, and TAU is ready when you leave the house. With the integrated 3-in-1 cable, you can charge numerous devices on the go at any time.

Always within reach. What does that mean?
Conventional power banks are often too heavy and bulky to carry with you all the time. TAU is so small and lightweight (only 40 g) that you can always have it with you, no matter where you go.

Always ready for use.
Thanks to the integrated 3-in-1 cable, TAU is compatible with many smartphones and mobile devices.
Dual: Lightning for Apple devices (iPhone, iPad, iPod, AirPods) + Micro USB devices.
USB-C: compatible with Android and Google smartphones as well as the latest generation of portable devices.

Quick, effortless setup
Place the reusable nano suction pad on any surface, plug in the included cable, and TAU is ready to go immediately. Screws and dowels are also included if you're handy and sure you want to mount the charging dock in just one location.
