    Always charged. How is it possible?
    The TAU®’s magnetic charging dock fixes onto a counter or wall easily, making it effortless to recharge your power back. Just hang your keys on the dock when you get home and the TAU will be ready to go when you head out next! The integrated cables mean that you can be ready to charge any device at any time. 

    Always with you. What does that mean?
    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. 

    Alway ready to use. 
    TAU® is compatible with every smartphone and portable device thanks to its two integrated cables:
    - Dual: Lightning for Apple devices (iPhone, iPad, iPad Air, Airpods) + MicroUSB devices
    - USB-C: compatible with latest Android and Google phones and newest generation portable devices


    Effortless setup 
    
Place the repositionable 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.
