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 simple and seamless as hanging up your keys when you get home. The Tau's magnetic charging station can be easily attached to your countertop or wall, allowing you to recharge your battery effortlessly. Just 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'll always be 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.
