The charger for the Galaxy Fit3 typically includes a magnetic charging element that connects directly to the watch. It does not have a traditional USB plug on both ends; instead, it usually comes with a USB-C connector on one end for plugging into a power source, and the other end is designed to magnetically attach to the watch for charging. If your charger seems to have a configuration that doesn't fit into a standard charger, it might be a misunderstanding or a different type of adapter. The standard charger should be a simple magnetic dock that attaches to the watch and connects to a USB port for power.
