If your Apple Watch is not charging on the USB-C Magnetic Charging Dock for Apple Watch (ST-TCMCAWM), check the LED indicator first, because it confirms whether the dock is receiving power at all. The USB-C Magnetic Charging Dock for Apple Watch plugs directly into a powered USB-C port, delivers up to 5W, and does not come with a power adapter.

How to fix charging problems with the USB-C Magnetic Charging Dock for Apple Watch

1. Plug the dock's USB-C connector into a powered USB-C port, then look at the LED indicator. The LED confirms the dock is receiving power.
2. If the LED is dark, change the power source. A power adapter is not included, so connect the dock to a USB-C port on a laptop, iPad, or Mac, or to a USB-C Power Delivery wall adapter that supplies 18W or more.
3. Try a different USB-C port, and if you are using a wall adapter, try a different wall outlet.
4. Place your Apple Watch face up on the magnetic charging module. The magnets align the watch automatically, and the watch lights up and starts charging on its own.
5. Reposition the watch so the back of the case sits flat and centered on the charging module.
6. Clean the back of your Apple Watch and the charging surface of the dock. Dust or grit between the two surfaces stops the charge.
7. Check the USB-C connector on the dock and the port on your power source for debris, then reseat the dock.
8. Test a different Apple Watch on the dock, or your Apple Watch on another charger, to work out whether the issue is the dock or the watch.
9. Confirm what you are charging. The dock is MFi-certified and designed specifically for the Apple Watch, so it cannot charge other brands of smartwatch. It is compatible with all Apple Watch series.
10. Set the right expectation on speed. The USB-C Magnetic Charging Dock for Apple Watch delivers up to 5W, and the exact speed depends on your Apple Watch model and the power source you connect it to.
11. Remove your Apple Watch from the module once it is fully charged.
