November 17th, a noteworthy improvement of the new Apple Watch is that it supports fast charging. This means that your Apple Watch’s charging time will be further shortened, but there are still some details to pay attention to.

Which Apple Watch models support fast charging?
- Apple Watch Series 7
- Apple Watch Series 8

How long does it take to fast charge?
According to Apple officials, it takes about 45 minutes to charge the above-mentioned Apple Watch models from 0% to 80%. In an updated official support document from Apple, the specifics of fast charging for the Apple Watch Series 7, Apple Watch Series 8, and Apple Watch Ultra are detailed.
With Quick Charge, Apple Watch Series 8 and Apple Watch Series 7 go from 0% to 80% battery in about 45 minutes, and Apple Watch Ultra goes from 0% to 80% in about an hour*.
To achieve fast charging, what is needed?
IT House learned that the above three Apple Watch packages all come with a USB-C magnetic fast charging cable. It’s worth noting that the cable is made of aluminum, not plastic, on the ferrule.
For fast charging, the Apple USB-C Magnetic Fast Charge Cable is required. The cable’s magnetic charger and USB-C connector are wrapped in aluminum.
This USB-C magnetic fast charging cable can also be purchased separately, the length is 1 meter, the model is A2515, and the current price on Apple’s official website in China is 283 yuan. Naturally, users can also purchase through other channels such as Taobao, Tmall, and JD.com, but please pay attention to the model and whether it is genuine.

Another thing to pay attention to is the charging head part. According to Apple’s official documentation, a USB-C power adapter with a power of 5W and higher can quickly charge the Apple Watch.
You’ll also need one of the following power adapters:
- Apple 18W, 20W, 29W, 30W, 61W, 87W or 96W USB-C Power Adapter
- Equivalent third-party USB-C power adapters that support USB Power Delivery (USB-PD) at 5W or greater
