Rolling Square Tau 2 Keychain Charger

Tau 2.0 is the smallest 3-in-1 power bank in the world. Equipped with USB-C, Lightning, and MicroUSB cables, it is compatible with virtually every portable device. Thanks to the proprietary dock, charging is as easy and seamless as hanging your keys when you get home. The Tau's magnetic charging station 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 you 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.
