    Everything as expected!! The 3V output is actually 3.3V and works great with ESP8266 and ESP32 as mini UPS

    Very easy holder for the 18650 by the in- and out USB, and multiple connections for 3V and 5V. Perfect for the Arduino and many Led applications. Just trying to figure out which resistor to replace the 5V to 7V for Arduino.

    These charger boards are pretty OK. They're well made though one may wonder why they decided to put the LEDs on the bottom of the board rather than on the 18650 side: that's a pretty weird design decision. The markings says 3V but it is actually delivering 3.3V. The switch cuts the power of the USB output plug only, the three 3.3V and three 5V outputs are always ON. Some flux remains on the PCB. I had to bend the clips inside the 18650 holder to avoid the 18650 sleeve getting damaged when removing the battery. Overall, nice boards despite the horrendous and persistent smell of the plastic holder.

    These battery modules are excellent. I bought five more because they are very useful.

    These little 18650 battery modules are really good. I have just ordered more to use with the 18650 batteries I recently scavenged from an old laptop battery.

    Parts arrived in Switzerland within 4 weeks. They all look good, 2 parts tested, they work fine.
