Rolling Square TAU 2 Keyring Power Bank

Keyring power bank with 2,000 mAh, including charging cable for all mobile devices (USB-C, Lightning, Micro-USB)

TAU 2.0 is the world’s smallest 3-in-1 power bank. Equipped with USB-C, Lightning and MicroUSB cables, it is compatible with virtually any portable device. Thanks to the proprietary dock, charging is as simple and seamless as hanging up your keys when you get home.

ALWAYS CHARGED
The TAU®’s magnetic charging station can be easily attached to a countertop or wall, so you can top up your power bank with ease. Simply hang your keys on the charging station when you get home, and the TAU will be ready to go the next time you head out! Thanks to the integrated cables, you’re always ready to charge any device.

ALWAYS WITH YOU
Whilst conventional power banks are too bulky to carry in your bag and are often left behind, the TAU is so small and light (just 40g) that you’ll almost forget you’ve got it with you.

ALWAYS READY FOR USE
Thanks to its two integrated cables, the TAU is compatible with any smartphone and portable device:
- Dual: Lightning for Apple devices (iPhone, iPad, iPad Air, AirPods) + MicroUSB devices in one
- USB-C: compatible with the latest Android and Google phones and the latest generation of portable devices

EFFORTLESS SET-UP
Place the repositionable nano-suction pad wherever you like, connect the cable, and TAU is ready to use. And if you’re a DIY enthusiast and 100% certain you won’t be moving your dock, you can also use the screws included in the pack.

COMPATIBILITY
