The problems with standard power banks?
- They are bulky and hard to be carried around
- Most of the times we forget to recharge them
This is why we designed TAU, the smallest 3in1 power bank in the world with integrated cables, that snaps onto your keychain.
TAU’s magnetic charging dock can be fixed on a counter or on a wall, and be used as a key hanger.
When you arrive at home, just hang your keys on the dock, and TAU will charge back up, without even thinking about it!
