This authentic charging cable is made by and for Apple products, so you won't have to worry about your device overheating while juicing up. Magnets near the back of your watch will cause it to snap in place automatically, so it doesn't easily lose its grip and disconnect mid-charge. Don't be bound by a short cord, this extra long 2m (6.5 feet) cord offers convenience and flexibility. 2m genuine Apple Magnetic chargers are rare & hard to find. Excellent working condition.
