No one wants the bulky and tangled chargers anymore...and if all the power we need can be put in a little device, we'd take it. Right? This Smart Keychain replaces the typical charging cable and uses the microcomputer electronic system to wirelessly charge the touch-sensitive Apple Watch by simply placing the watch on a black magnetic charger. It's easy to use. The strong magnetic adsorption allows you to adjust the angle freely without deviating from the charger center. This charger with a built-in 950mAh lithium-ion battery can charge all iWatch series. Portable, pocket-size when you're outdoors, the pocket size of the portable charger will be carried around and it's easy to put in your pocket and bag while you're exercising.
