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 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 you the next time you head out.
