AWEMAZING power bank, it's certainly doing a great job.
I have bought many power banks in the past and I've always done proper comparison to find the best available product. I am still waiting for 2 power banks to be delivered, but sofar I have tested more than 10 and I am sure that sofar the Power Cube from Ampere LLC is Best of The Best!
This power bank is the only one I bought 2 from since the whole family loves to use them!
Ordered before Covid19 but some how received it and happy to use it
Nice! Very powerful and easy to use really compliments my Red Qi charger
Im very happy with my Power Cube. I had several occasions where I had no outlet or wall plug in the near.
I could charge all my Apple devices wirelessly via my Unravel and the Power Cube.
This especially helpful being a Sales Engineer who has to travel a lot.
Thanks for developing the Powercube.
I can use it for charging other devices at home office in addition to my using it in my travels.
The side of the battery is super sticky. Within minutes of being out of the box it looks like it is ten years old and I haven’t even put it in a bag yet. As well of the looks the stickiness turns my stomach if I touch it.
My order was lost and USPS is not cooperating with me to recover it or replace it.
