One of the more useful changes to recent Apple Watch models is support for fast charging. This allows you to quickly top off your Apple Watch battery at much faster speeds than before. There are a few things to keep in mind, and you don’t get everything you need in the box…

Which Apple Watch models support fast charging?

The following Apple Watch variants allow for fast charging:

  • Apple Watch Series 7
  • Apple Watch Series 8
  • Apple Watch Ultra

Apple says that with fast charge, your Apple Watch battery level can go from 0-80% in about 45 minutes. Apple has a support document detailing the specifics of fast charging with the Apple Watch Series 7, Apple Watch Series 8, and Apple Watch Ultra.

What do you need to fast charge your Apple Watch?

Included with the Apple Watch is an Apple USB-C Magnetic Fast Charging Cable. As we’ve previously reported, the difference with this cable is that it has aluminum instead of plastic around the magnetic charger.

The second part of the equation is the power adapter that you plug into the wall. As part of its continued focus on reducing its environmental footprint, Apple no longer includes this power brick in the box. This means you’ll have to use one that you already have or buy a new one.

Here are the specifications from Apple:

  • 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

Finally, if you use Apple’s MagSafe Duo or its Apple Watch Magnetic Charging Dock, you can’t tap into fast-charging capabilities, regardless of which cable or power adapter you use. You could, however, place the fast charger puck in a third-party dock of any sort.
