I somehow lost my original charger cable. I decided to buy two so I can hide one in a safe place and keep the other handy to charge the watch. Both cables provide a reliable connection. One of Garmin's weaknesses IMO is that many of their charging cables don't connect well to the watch. I think this watch was an exception, but it was still nice to know that these other manufacturers' cables didn't have such issues. The cable is a bit thick and hard. I don't know if it's + or -. Doesn't seem to be a problem, just mentioned it.
