When Apple unveiled the new Apple Watch Series 7 back in September, it noted that the wearable boasts a new charging architecture that allows it to recharge up to 33% faster than the Series 6, charging from 0% to 80% in 45 minutes.
A new USB-C charging cable (included in the box with the Watch, as well as being sold separately) is required to enable fast-charging on the Series 7. However, until now Apple hasn’t provided information about what wattage of power is required for fast charging.
In a new support document published today, Apple says any of its USB-C power adapters rated at 18 watts or higher will support fast charging on the new wearable. Third-party USB-C adapters rated at 5 watts or higher will allow for fast charging as long as they support the USB Power Delivery (USB-PD) protocol.
Fast charging requires an Apple USB-C Magnetic Fast Charging Cable. This cable has aluminum around the magnetic charger and a USB-C connector.
You also need one of these power adapters:
- 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 is not available in Argentina, India, or Vietnam.
