ETEIZU Smart Watch Charger Cable 4 Pin 7.62 mm

Universal 4-Pin Magnetic Charger

This ETEIZU cable charges smart watches and fitness trackers that use a four-pin magnetic connector with a 7.62 mm contact spacing. It connects to any standard USB power source so you can top up a wearable at a desk, in a car or from a power bank without carrying a proprietary dock. The magnetic tip snaps into place automatically, making it practical for daily top-ups or overnight charging. Buyers whose devices use a different pin count, spacing or proprietary connector cannot use this cable.

Fits Any USB Port And Frees Up Outlets

Plug the USB-A end into a laptop, wall adapter, car charger or portable battery and the magnetic head aligns itself to the watch contacts. No separate charging cradle or AC block is required, so a single USB port handles both data tasks and wearable power. The 6000-bend rated cable resists fraying when coiled in a bag or bent at a nightstand. Builds that rely on a dedicated charging stand or a proprietary wall wart will not benefit from this design.

Steady Output During Full Charge Cycles

The copper-core conductors and ABS/PVC sheath deliver stable current throughout the 2.5 hour charge cycle, and built-in over-voltage and over-current protection cuts power if the supply drifts out of safe limits. Magnetic attachment stays secure even if the cable is nudged, preventing intermittent contact that can extend charge time. Users who need rapid top-ups in minutes rather than a full recharge cycle will not see a speed advantage from this accessory.
