    Though it can be used to power raspberry pi & so, it can’t be used as UPS for any since there is a ~0.5s power interuption when we connect it to mains.


  2. abhisheksarkar1990 (verified owner)

    Excellent board. Runs my Pi 4 for ~4hrs while streaming music and web browsing.

    Needs a case, which can be 3D printed.


  3. hanubgl (verified owner)

    1. the board is well made
    2. has both m-usb and usb-c to charge
    3. has switch to on/off
    4. DOES NOT WORK AS UPS, which means the load will reboot, when charging power goes on/off.


  4. souman.ray (verified owner)

    very convenient & reliable solution


  5. aniket.howrah (verified owner)
