Don't Overcharge!

By Mike
Rated 3 out of 5

I got one of these things a few years ago looking for a cheep & effective charger for my new GoPro-10. Now a few years later, my batteries are all puffing up (not good). There is no charge controller here and if you leave them plugged in and Green for an extended period, your going to overcharge and shorten your batteries. BUT IT DOES WORK. Especially with a USB-C cable. So three Stars

I'm not sure about this thing

I noticed it has only 2 prongs connecting to the battery, for positive and negative power. The other terminals normally connecting to a lithium battery are to monitor its temperature and prevent overcharging, damage and explosions/fire. I connected the Watson Mini Duo charger to a GoPro Endura battery that I had already fully charged using the camera. The red charging indicator lit and stayed lit for at least 20 minutes, at which time I unplugged it for fear of damaging the battery. Please tell me I'm wrong, but may have gone too cheap with this.
