Rolling Square TAU 2 key ring

Tau 2.0 is the world's smallest 3-in-1 power bank. 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 Tau's magnetic charging station can be easily attached to a countertop 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 to go the next time you head out! With the integrated 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.

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) + MicroUSB devices in one
• USB-C: compatible with the latest Android and Google phones and next-generation portable devices

Place the repositionable nano suction layer wherever you want, 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.

Compatibility:

• Lightning (iPhone, iPad, iPod, AirPods)
• USB-C devices
• MicroUSB devices.
