You can use a standard USB-A or USB-C plug as a reference tool. If your watch's spacing matches this measurement, the cable will fit. If not, it will not be compatible. Always double-check your specific watch model against the compatibility table above before purchasing.

Q: Can I use a fast charger or quick charge adapter with this cable?

A: No — it is strongly recommended to use only a standard 5V/1A power source such as a computer USB port, laptop, or standard wall adapter. Using a quick charger that exceeds 5V or 1A may damage your smartwatch's battery or charging circuit.

Q: Is this the same as other similar-looking smartwatch charging cables on the market?

A: Not necessarily. Many cables look identical but have different pin spacings. This cable has a 2.84mm charge spacing, which is specific to certain models. Always verify the spacing before purchasing to avoid receiving an incompatible charger.
