TAU® 2 - Emergency keyring power bank

Pretty good with 1 major flaw

I theoretically could get 20 to 30% battery charge when used, it's nice to have emergency backup charge whatever but it's biggest flaw and my biggest issue is it would fall off semi occasionally in my pocket or on the ground because the clip came loose. And due to that today it fell off and I have no clue where it's at. So I am out a power bank and money because of a week plus a clip that couldn't hold the power Banks wait that well.

This thing has already come in very handy in the short time that I have had it! All of the features are amazing!

The good, the bad, the in-between

Honestly this is one of the most useful and best tools I've ever had. It's impressed many people and helped me out so many times. I truly cannot count the amount of times it's helped me and my friends out. Honestly for usefulness it's phenomenal 10/10. The only bad and in-between is the holder. I constantly take my keys in and out my pocket. I mean who doesn't. The clip itself works really well for a good amount of time, until it doesn't. Once and awhile the tau will fall of your keychain holder or get tugged too hard in your pocket and fall off when grabbing your keys. After the tau falls once it usually would get scratched or small bits chipped on it. These small chips stop the holder from holding on as great and it's just a process of falling over and over again. I've also noticed small cracks in the keychain holder as well where it connects to hold the tau. It's just time and use that degrades the tau. It's a amazing product but I can't tell you how many times I've lost the tau and found it sitting in my driveway or something similar haha. All in all amazing charger just in my opinion key usage may not be the best but as a lanyard holder or something like that for sure I'd go for it. I still recommend it just putting this out there to be aware there are flaws.
