USB-C magnetic charger for Apple Watch

This ViewSonic cable connects a USB-C power source to an Apple Watch using a magnetic charging puck. It supports every Watch series from Series 2 through Ultra 2, including all case sizes from 38 mm to 45 mm. The 1 metre white cable is built from polycarbonate and weighs only 0.03 kg, making it light enough for travel or desk use. Buyers who need a Lightning connector or a multi-device dock will not be served by this single-purpose cable.

Sustained charging behaviour

The charger delivers a steady 5 V at 1 A for a 5 W output, matching Apple’s baseline charging profile rather than a fast-burst mode. Built-in overcurrent, overvoltage, short-circuit and overtemperature protection keeps the watch battery safe during long overnight sessions. The specification sheet notes that a 20 W to 30 W USB-C PD adapter gives the best results, but the cable itself never exceeds the 5 W limit. Users who expect rapid top-ups in minutes will find the pace unchanged from the standard Apple puck.

Installation and common issues

Plug the USB-C end into any compliant charger or port, snap the magnetic puck to the back of the watch, and charging begins — no drivers or pairing required. The most frequent problem is leaving a thick or metal watch case on the device, which blocks the magnetic alignment and stops power transfer. A second issue appears when the source adapter cannot negotiate 5 V 1 A, causing the puck to cycle on and off. The cable carries a 12-month quality assurance from ViewSonic.

Questions about this item

How hot does the ViewSonic USB C iWatch charger get when it runs all day at 5 watts?

It draws only 5 watts at 5 volts and 1 amp, so heat stays low during continuous indoor or outdoor use.

What power adapter must I already own for this charger to work?

You need a USB-C PD adapter rated 20 W to 30 W; a 5 V / 1 A adapter or the original Apple adapter also works.

Will the magnetic puck charge my older 38 mm Series 3 alongside the newer Ultra 2?

Yes, the charger supports every listed size from 38 mm up to 45 mm, covering Series 3 through Ultra 2.
