    Excellent UPS for 5V. I tried it with Raspberry 3 B, and Raspberry did not report any undervoltage message.

    This thing is actually a UPS. Will maintain output with no interruption when either the battery or the input 5V is disconnected. Charges batteries to 4.1V steady (using protected 18650 cells, always good to be safe). Have not finished testing discharge level yet.

    Have been using this now for a couple of months - is excellent for occasional power outages - in my application was able to provide power for 4 hours using 2 x 2000mah batteries. The only thing I can see is that there's no low-voltage cut-off, which would lead to battery damage in time, as it would have run them flat had I not removed them for that time.

    Perfect power backup for 5V powered devices not requiring much current. The max duration depends on the capacity of 18650 batteries used and the current required by the device. balancing both things you can have a very useful device to maintain service with power cuts.
