Stumbled across this lost thing, it’s a portable garmin charger. Or straight up usbc charger. Holds 1200mAh and my instinct 3 44m says it has 350mAh. So theoretically, simple thing could charge my watch 3 times (energy loss accounted) and be charged over 200+ days on power save, if it was thrown in a dark drawer. With solar maintenance charging reckon this little thing would charge for an entire year and be great in a go-bag or for extended trips to keep the watch going even while using gps or maps or heavy usage 👍 found cheap on Amazon. There might be better ones even!
