All the features of TAU® in a 1000 pieces limited edition “MARS RED”

Last year we’ve designed TAU®, to give you the perfect power boost in emergency situations. TAU® provides on average an extra 40% of battery, when you most need it. Today TAU® is back in the “Mars Red” colorway, for a limited number of pieces.

The smallest universal power bank in the world

Featuring USB-C, Lightning and MicroUSB cables, TAU® is compatible
with virtually smartphone and portable device.

Always with you!

A power bank has never been so light and compact.

Standard power banks are too bulky to be carried in your pocket and often left behind.

TAU® snaps on your keyring and it’s so small and light (40g / 1.4oz) that you will forget you have it with you, until you need it.

The power bank that is always charged!

Thanks to its proprietary charging dock, you will never forget to charge your TAU®.
Once you get back at home, just place your keys with TAU® in its magnetic charging dock, so when you go out, you will always have a fully charged power bank with you.

Effortless setup

Place the repositionable nano suction layer where you prefer, plug the cable and TAU® is ready to use. And if you are a DIY aficionado and 100% sure that you aren't going to move your dock, you can also use the screws included in the packaging.
