I have a barcode scanner that has a small lithium ion battery inside. Just recently the proprietary charging port broke and the unit will now no longer charge by cable. I started researching an option to charge the battery outside of the scanner and came across this unit. I wasn't sure which connector I needed because at a 3.7V battery and a 2 pin plug it seemed like it might be the same micro JST connector popular in the remote control hobby. Unfortunately there are numerous sizes and styles of connectors so I took a gamble with this one. Luckily the connector fits perfectly and the battery charged to full within an hour at the 0.6A charge rate. The indicator light shows green to show the battery is charging, and turns off when it is complete. The battery didn't get warm, the build quality of the board seems very good, and the expandability to have 6 batteries charging at once is great.

Fais ce qu'il doit faire.

I plug this into the USB socket of a car jump-start battery to charge model airplane batteries. It works well. The flashing that indicates a live socket with no battery is fast and a little hard to see in sunlight. Green indicates charging, which is easy to see. No LED indicates that charging is complete. Not really a problem, but it'd be better to have a different color or a different flash rather than nothing. At the price you really can't fault it. My wife is going to like it because it doesn't emit a loud beep when the battery is full.

**I would recommend some knowledge of batteries, and a multimeter check before use to be safe! ** This thing is working great for me and charging my batteries for my LoRa boards on the go. The charging ports are very secure and there is no worry about them coming apart when removing or if a battery dangles while charging (though I don’t recommend this). The usb connection is also very strong, it does not wobble. While the quality of the board does not feel “quality” it does not feel like junk either. The soldiering is not perfect, but it works. I have done worse jobs myself. Summary: I wouldn’t throw batteries in this and leave the room, but is a great solution to bulky converters or an expensive set up to someone new to a hobby that uses these batteries.
