Which UPS power supply to choose for the Pi 4?

Last Updated on October 6, 2023 by pg@petergamma.org

We already have reviewed two such devices in our journal,which where not suitable for our purpose. But here is another one:

  • It offers 3 – 4 hours of battery running time for a Pi 4.
  • it has usb charge.
  • It has a connector for external battery available if we want more power
  • It has a usb 2 output to power the Pi

Issue we personally have with this device:

  • It needs GPIO pins for battery monitoring:

  • the other two boards which we introduced here does not require this. occupied GPIO pins is an obstacle for us personally

But which one to choose of these three? All of them have issues. And we still haven’t found what we are looking for.
