Tau® Keychain Power Bank

Regular price $24.99

The problem with regular power banks? Once they discharge, most of the times people forget to charge them back.

This is why inCharge we designed Tau, an ultra-compact 3-in-1 power bank that snaps onto your keychain.

Thanks to its magnetic charging dock, users will just have to hang their keys for Tau to start charging right away.
