Works as expected
This 18650 UPS (Charger and Boost Converter) works as expected. A full schematic would be useful to understand the KEY function & the DNL'd devices. Mod'd the board so a SMD pushbutton is wired in series for the output LED so that it wasn't drawing power from the battery illuminating the LED all the time. A SMD SPST slider added @ SW contacts to turn output on/off. Am happy. Recommended.

Can only output 5v
Works in 5v, if you soldier SW together. Useless for original purpose, but may be used to run some arduino boards later. One star for dishonest description.

Great microcontroller backup system
Have used many of these units to power and provide power backup to microcontroller projects. Work well and well priced.

Basic but works
Basic function works fine. Charges at about 600mA, a few hours for most batteries.

Misleading description and no documentation
There is no documentation on how to switch voltage. information was given in a response to a question but it does not tell you that you must change out a SMD resistor.
