Nice little unit
I have a mqtt server running on a Raspberry Pi Zero 2W. This keeps my server running if there is any power issues or i feel like taking the device with me when traveling. I used a recycled laptop battery pack to source a 18650. I get about 3-5hours runtime from 1 2200mah 18650 with power settings on the pi set low as possible with minimal server utilization.

USB ports did not work
UPS worked great. However, I could not get USB hub to work at all, so I had to return.

Excellent and ethical business!
I accidentally broke my board and they acknowledged that the problem may have been the quality of the battery holder. They additionally replaced my battery board with a new version (V1.5) which is slightly larger and has a stronger battery holder that seems to be designed for you to more easily remove the battery and replace it. I am super enthusiastic about this company now.
