I've been using it to charge my Xbox series controller for about a month and it's working great. I got this because I wanted to make sure I wasn't overcharging, and because I accidentally bought the wrong battery model, the Microsoft LED charging cable that came with it wasn't a USB-C. Lights up red when charging and blue when finished. I didn't time it so I'm not sure, but it took me 2-3 hours to fully charge it via USB on my PC (while playing). For now I can definitely recommend it!
