What it is and who it's for

This two-pack of magnetic USB cables charges compatible smartwatches from a standard USB port. Each cable measures 3.3 ft and uses a male-to-male connector with a magnetic tip. It suits owners of listed models who need a spare or replacement charger for home, office or travel.

Capacity and headroom

The magnetic tip snaps onto the watch when the contact spacing matches 2.84 mm or .11 in. A full charge takes about 2.5 hours and the cable includes over-voltage and over-current protection. It draws power from any USB-A source such as a laptop, wall adapter or power bank.

Compatibility check

Measure the distance between the centre points of the two charging pins on your watch; if it equals 2.84 mm or .11 in the cable will connect. The list of supported models includes SW021, SW023, SW025, ID205L, ID205G, ID205U, ID205S, ID206, ID216 and Uwatch 3S/Urun series.

Questions about this item

Will the SW021 magnetic connector still snap onto my older ID205L watch if the port spacing matches 2.84mm?

Yes — the cable is built for any watch whose two magnetic contact centres sit 2.84mm apart, which includes the ID205L and other listed models.

How do I know the cable is charging my SW021 watch correctly once I plug it in?

The watch itself shows a charging indicator when the magnetic end makes proper contact and the USB end is powered.

Does the 2-pack include a wall adapter or only the two 3.3 ft USB cables?

Only the two 3.3 ft magnetic USB cables are in the box; a USB power source such as a wall charger, computer port or power bank must be supplied separately.
