Apple 18W, 20W, 29W, 30W, 61W, 87W, or 96W USB-C Power Adapter
A comparable third-party USB-C power adapter that supports USB Power Delivery (USB-PD) of 5W or greater
Fast charging might not work in conditions that are too cold or too hot. If you have enabled cellular capability on your Apple Watch, keep your paired iPhone within range of your Apple Watch when fast charging.
If you're not sure which Apple Power Adapter you have, check the wattage on the top or bottom of the adapter:
