Product details

Tau is the smallest 3-in-1 power bank in the world. Equipped with USB-C, Lightning, and MicroUSB cables, it is compatible with virtually any portable device. Thanks to the proprietary dock, charging is as easy and seamless as hanging up your keys when you get home.

The magnetic charging station of the Tau can be easily attached to the counter or wall, allowing you to recharge your battery effortlessly. Simply hang your keys on the charging station when you arrive home, and the Tau will be ready for use the next time you head out. With the built-in cables, you are always prepared to charge any device.

While traditional power banks are too bulky to carry in your pocket and are often left behind, the Tau is so small and lightweight (only 40 g) that you'll almost forget you have it with you.

Place the repositionable nano suction layer wherever you want, plug in the cable, and the Tau is ready to go. And if you're a DIY enthusiast and 100% sure you won't be moving your dock, you can also use the screws included in the packaging.
