I have a charge 2 and it doesn't charge at all. I have cleaned all the pins and it still doesn't charge. The funny thing about this is that after being plugged in for a few hours, the tracker is HOT. I was wearing after it died, so I put it on the charger and took it off at 40% as I was going to use it. After that it hasn't charged at all, but still getting HOT if plugged in to an original charger and a USB wall plug.
