## Long description

TAU® is a compact portable power bank compatible with Apple (Lightning), MicroUSB and USB-C devices. With a 1400 mAh capacity, it delivers roughly an additional 40% battery life on average for most smartphones, providing a short emergency boost when you need it. The Mars Red colorway is available for a limited number of pieces. Its small size and 40 g weight make it convenient to carry on a keyring or in a pocket.
Advantages
The integrated charging cables eliminate the need to carry separate leads, allowing immediate connection to a wide range of devices. A magnetic charging dock attaches to a counter or wall for easy recharging and doubles as a key hanger, so the power bank is ready when you head out. The unit’s lightweight, pocket-sized design reduces the chance of leaving it behind while still offering reliable emergency power.

How to use
Choose the model with the appropriate integrated cable for your device (Dual for Lightning + MicroUSB or USB-C). To charge a device, connect it directly to the integrated cable and press any required wake/power button on your device; charging begins automatically. To recharge the TAU® power bank, place it on the magnetic charging dock and connect the dock to mains power using the supplied cable. The repositionable nano-suction layer lets you place the dock on a preferred flat surface; screws are included if you prefer a permanent installation.
Usage recommendations
Keep the power bank attached to your keys or in a consistent spot on arrival at home so it is always recharging on the magnetic dock. Use the Dual model for mixed Apple and MicroUSB device households and the USB-C model for newer Android and USB-C devices. Avoid exposing the unit to extreme temperatures and moisture to maintain battery performance.
