Smart-watch charging kit

This 2-pack supplies two 3.3 ft magnetic USB cables built for compatible smartwatches including models SW021, SW023, SW025, ID205L, ID205G, ID205U, ID205S, ID206, ID216 and Uwatch 3S. The connector centre-to-centre spacing must measure 2.84 mm or 0.11 in for a correct fit. Each cable plugs into any standard USB port on a laptop, PC or adapter.

Magnetic attachment under daily use

Pure copper probes create a strong magnetic hold that snaps the cable onto the watch charging points automatically, keeping the connection stable while the device rests on a desk or nightstand. Built-in over-voltage and over-current protection guards the watch during the full 2.5 hour charge cycle. The 3.3 ft length gives enough slack for bedside or desk-top routing without strain.

Connector spacing decides compatibility

The single specification that determines whether this cable works is the 2.84 mm centre-to-centre distance between the two magnetic charging pins. If the watch uses a different pin pitch the magnets will not align and charging will not start. Buyers who need a different pin spacing or a proprietary dock connector cannot use this kit.

Questions about this item

Does the 3.3 ft magnetic cable generate noticeable heat or draw excess power during all-day charging?

The cable uses a pure copper probe with built-in overvoltage and overcurrent protection, so it stays cool and draws only the power the watch requires.

What USB power source must I already have to use the SW021 charger?

Any standard USB-A port on a PC, laptop or USB wall adapter will power the magnetic connector.

Will the 2.84 mm magnet spacing work with my older ID205L or ID206 smartwatch?

Yes — the 2-pack is compatible with ID205L, ID206, ID216 and other listed models that share the 2.84 mm centre-to-centre pin distance.
