    Excellent execution.

    I purchased that package on the basis of the unique cable idea. The units are exactly what was promoted. Excellent design and very functional. I also ordered the Tau. It is very disappointing in its charge capacity. Barely provides a 30% charge to my Samsung Note 9. Will continue to carry and use my current power bank.

    Incredibly handy

    I bought 4 of these, they are extremely useful and the magnetic charging strength is impressive. 4 stars because I would love to have more colors.

    Truly unique products, well-built and good customer support!

    I don't recall where I came upon the inCharge X cable...but I'm glad I checked out their website. First off, the cable is truly unique...I also couldn't believe the lightning cable end doubled as micro-usb end...never seen that before. I wasn't sure I could plug it in to both so reached out to chat with customer service. The chat came a few hours later but overall I was pleased with their service and again, kind of shocked that the lightning end could do both...but it does. The build quality of the cable and the TAU charger I purchased seem solid, really nice...I'm very pleased with the purchase. The TAU is a great design as well--both are only a few weeks old but again, I'm very pleased with both!


    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.

    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.

    Always Charged

    Thanks to its dock, you will never forget to charge 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.
