Great backup module for 5V. Supports two 18650 batteries which in addition to serving as charger also has a 5V output with power. I haven’t done the final installation yet but in the tests it worked perfectly.

I love these boards, but use them to power offgrid light. With the 3 orders free shipping page found some lights and led strips that work with 12 volt(also waterproof boxes and cable glands). The save continues usage is 0.5 ampere or 6 watt with the 12v version(of actual usage not declared), with some small aluminium heatsinks it won’t overheat. Using 2 undeclared cheap 18650(1300/1500 mah) it can power the 20 watt floodlight safely for 1 hour and 30 watt for approximately 45 minutes, this board wil then give smaller light, you should turn the light off then because these boards wil go below/beyond safe discharge(it went to 3.7 volt). So it could power approximately 1 meter of led strip per board. in the picture I power a 12v 9 watt g4 cob led and the other one is the 12v 20watt floodlight, just a single because with 2 it would overheat in 20 seconds. Last 2 pictures are the 30 watt floodlight, it would be more than adequate to give light for a 1 meter deep and 2 meter wide patio.
