TAU is the power bank for every device (Apple, MicroUSB, USB-C) and so small that you can attach it to your keys while carrying it.

Always charged. How is that possible? The magnetic charging station of the TAU can easily be attached to a counter or wall, allowing you to recharge your power effortlessly. Just hang your keys on the charging station when you get home, and the TAU will be ready for your next trip! Thanks to the integrated cables, you can charge any device at any time.

Always with you. What does that mean? When standard power banks are too bulky to carry in your bag and are often forgotten, the TAU is so small and lightweight (only 40 g/1.4 oz) that you’ll almost forget you have it with you.

Always ready to go. The TAU is compatible with every smartphone and portable device thanks to its two integrated cables:

• Dual: Lightning for Apple devices (iPhone, iPad, iPad Air, AirPods) and MicroUSB devices
• USB-C: compatible with the latest Android and Google phones as well as next-generation portable devices

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