  • Accessory categoryAccessories
  • Universal 4 mm fit works with most smartwatches and fitness trackers
  • Strong magnets and copper probes auto-align for firm adsorption during charging
  • Stable 5 V/1000 mA output with over-voltage and short-circuit protection
  • Premium ABS housing and PVC cable withstand 5000+ bends without fraying
  • Swappable magnet polarity fixes charging issues on mismatched devices

Universal 4 mm Magnetic Charging

This two-pack provides replacement USB charging cables for smartwatches and fitness trackers that use a 2-pin magnetic connector with a 4 mm ± .2 centre distance. Buyers should measure their device before ordering to confirm the pin spacing matches. The cables are designed for users who need a spare or travel-ready charger for compatible wearables. They are not suited for devices that use proprietary multi-pin docks, larger magnetic arrays, or wireless charging only.

5 V 1000 mA Output Headroom

Each cable delivers a stable 5 V / 1000 mA current, allowing a full charge in roughly two hours for typical wearable batteries. Built-in over-voltage, over-current and short-circuit protection helps preserve battery health during daily use. The 1000 mA limit means the cables cannot fast-charge larger devices such as tablets or phones that require higher amperage. They are also unsuitable for wearables that demand a higher voltage or a proprietary handshake protocol.

Strong Magnets & 5000+ Bend Durability

Upgraded magnets and pure copper probes give quick auto-alignment and firm adsorption to prevent accidental disconnects while reducing connector wear. Premium ABS housing with flexible PVC cable withstands 5000+ bends without fraying for long-term reliability. If charging fails due to reversed polarity, the magnets can be swapped to match the device. The lightweight cables plug into any standard USB-A port, power bank or wall adapter for convenient charging anywhere.

Questions about this item

Will the 4 mm pin spacing on this charger fit the 2-pin port on my older smartwatch?

The cable uses a 2-pin magnetic interface with a 4 mm ± .2 mm center distance, so it fits devices built to that spacing.

How can I confirm the cable is delivering the rated 5 V/1000 mA output after I plug it in?

A full charge in about 2 hours indicates the charger is providing the specified 5 V/1000 mA output.

Do the two cables in the pack come with a wall adapter or power bank, or must I supply my own USB power source?

Only the two magnetic USB charging cables are included; you need to provide a USB port, power bank or wall adapter separately.
