    The best emergency power bank IMO

    I was sincerely very happy when I received the second version of the emergency power bank. This thing is already attached to my keys the day I received it. The instructions on how to use it was considerably easy and the charger is small and amazing compared to the first version. My favorite part of Tau 2 is the ability to charge from the wall it self so I don't need to take apart the magnetic charger and bring it with me everytime I travel.

    Fast iPhone Charging and Well Made

    My initial impressions of the Tau2 are enthusiastically positive. The craftsmanship is excellent. All the parts fit together seamlessly. I like the charging dock, which is easy to use. When I used the Tau2 to charge an iPhone 12 Pro that was streaming video, the phone battery quickly went from 31% to about 80%. Overall, this was a good purchase.

    Purchased from Kickstarter

    Purchased from Kickstarter. Plenty of communication from start to finish. The TAU 2 I received was brilliant and I would definitely buy from them again
