Description: If you need to charge LiPo batteries, this simple charger will do just that, and do it fast! The SparkFun USB LiPo Charger is a basic charging circuit that allows you to charge 3.7V LiPo cells at a rate of 500mA or 100mA. It is designed to charge single-cell Li-Ion or Li-Polymer batteries.
The board incorporates a charging circuit, status LED, selectable solder jumper for 500mA or 100mA charging current, external LED footprint, USB input, two pre-installed JST connectors for SYS OUT and BATT IN, and (back by popular demand) a barrel jack connector.
There is also a ‘SYS OUT’ with a pre-installed JST connector which allows you to connect the charging circuit directly to your project so you don’t need to disconnect the charger each time you want to use it.

I tested it with the wall plug first and it worked as advertised so I installed it in my build. Once installed I wanted to charge it via USB and when I tried to plug it in all solder points came lose and the entire USB socket came off so I had no other choice but to use the wall plug. Too bad. I wanted to have both options but because of bad manufacturing I was left with one.
Those USB ports tend to be more resilient. I’m contacting you privately to discuss your issues. Thanks
