If standard power banks are too bulky to be carried in your pockets and often left behind, TAU® is so small and light (only 40g/1.4oz) that you will almost forget to have it with you. TAU® is fitted with integrated universal connectors that are compatible with Lightning, USB-C, and MicroUSB Devices. Keep it charged using the TAU®’s magnetic charging dock that you can easily fix onto a counter or wall, making it effortless to recharge your power back. Place the positionable nano suction layer where you prefer, plug the cable in 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.
