Understanding the 4 Pin Charger
The 4 pin charger is specifically designed to connect to smartwatches that use a 4-pin charging interface. The pins align with the charging contacts on the back of the watch to provide power efficiently. Knowing this helped me avoid generic chargers that wouldn’t fit or charge properly.
