Portable Charger for Galaxy Watch 4/3

This compact USB keychain charger is designed for owners of Samsung Galaxy Watch 4, Watch 3, Active and Active 2 models. It replaces a bulky dock with a pocket-sized unit that plugs directly into any USB-A port. Travellers and commuters who want a minimal charging solution will find it fits easily into a bag or pocket.

Magnetic Dock with Keychain Loop

The built-in magnetic module snaps the watch into alignment instantly, so there is no fumbling with cables or precise placement. Simply insert the USB end into a power bank, laptop or wall adapter and attach the watch. The keychain loop secures the charger to keys or a strap, reducing the chance of misplacing the small device while on the move.

Single-Watch Power from Any USB-A Source

The charger delivers the watch’s original charging speed through its intelligent chip and draws power from standard USB-A outputs. It handles one compatible Galaxy Watch per session and cannot charge multiple devices simultaneously. Buyers needing to power a phone, earbuds or a second watch at the same time will require an additional charger or a multi-port hub.

Questions about this item

How can I confirm the charger is powering my Galaxy Watch 4 correctly after plugging it in?

The watch screen displays the charging animation immediately when the magnetic module contacts the back of the case, and the LED on the USB plug stays solid while power flows.

What accessories are included with the keychain charger and what must I provide separately?

The keychain charger itself is the only item supplied; you need a USB-A power source such as a laptop port, wall adapter or power bank to operate it.

My household has a Galaxy Watch 4 Classic and an Active 2 — which version of this charger works for both?

A single unit covers both models because the magnetic induction module is designed for the shared charging coil layout used across the Watch 4, Watch 3, Active and Active 2 series.
