Rolling Square TAU – Mini Powerbank 3in1, 1400 mAh, White

USB-C, Lightning or Micro USB? TAU has all 3

The powerbank contains 3 types of power connectors and thus offers compatibility with smartphones, wireless headphones or wearables and smart electronics. The hinged dual Micro USB / Lightning connector on one side and the USB-C connector on the other side are protected from dirt in the compact body of the powerbank.

Transform TAU powerbank into a keychain

Thanks to its small size and low weight, the power bank will become your essential travel companion. You will never forget TAU because you can easily attach it to your apartment or car keys. You will always have a backup power source at hand in the form of a stylish accessory with an original design.

Have your keys ready and charge TAU at the same time

When you get home, all you have to do is hang the power bank with the keys in the magnetic charging dock – TAU will start charging automatically. This way, you will always have a backup power supply for dead smartphone or other electronics. Attach the power station anywhere on the wall near the outlet using double-sided adhesive tape or the set of screws and wall plugs included in the package.
