    The product works perfectly, but be careful when putting the cell in this module, i accidentally put the cell in the wrong way, and then the ic of this module burned.


  2. ashutoshprusty29 (verified owner)

    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.


  3. 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.


  4. 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.


  5. souman.ray (verified owner)

    very convenient & reliable solution


  6. aniket.howrah (verified owner)

    Very nicely constructed. Looks and feels premium. Works as mentioned. No complaints at all.


  7. tojeevansingh (verified owner)

    works great with raspberry pi also. Should come with a case.
