    Clever,, innovative design......but cannot do it all.

    I so wanted this little power bank to be THE travel recharging solution for my iPhone AND new iPad Pro. The small power bank is handy. light weight, and, if you have a good spot to wall mount it near an outlet, it, can be always waiting, fully charged. Clever uncluttered design. The power bank works well and quickly to charge the phone but.. sadly, cannot charge the iPad.

    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 - Patented connector combining Lightning for Apple devices (iPhone, iPad, AirPods) + Micro USB (older portable devices / Android phones)
    • USB-C - Compatible with any Android phone 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.
