Fast charging on the Apple Watch: Everything you need to know

One of the most useful features and one that I personally liked the most about the latest Apple Watch models is the fast charging support. This allows you to quickly recharge your Apple Watch battery at any time of day at much faster speeds than before and allows us to have the clock at any time for tasks like tracking sleep, running a workout, or just getting to the end of the day. But there are several things to take into account and knowing that not everything you need comes in the box.

First of all, What Apple Watch models support fast charging? Only three models:

  • Apple WatchSeries 7
  • Apple WatchSeries 8
  • Apple Watch Ultra

In these three models, Apple indicates that, with fast charging, your Apple Watch can be charged from 0 to 80% in about 45 minutes (and this, in practice, is more or less accurate). Apple has a support document that details the specifications for this fast charge, in case you want to take a look.

Now, what do we need to use fast charging on our Apple Watch? Well, first of all, dWe should know that Apple includes a USB-C charging cable that supports fast charging in the box of these three compatible models. That is, the cable itself, should support this functionality (as much as it is MFI, it may not be). If you are thinking of buying one on Amazon or any platform, keep that in mind. The difference of this cable with the previous ones that Apple included, is the aluminum that it uses in the magnetic part instead of the white plastic.

The second part of the equation is the power adapter that plugs into the wall. As part of its “continued effort to reduce its environmental footprint,” Apple also doesn’t include this power adapter in the Apple Watch box like it did with the iPhone. This means that you will have to use one you already have or buy a new one.

Apple says that cAny 5W or higher USB Power Delivery-compliant USB-C power adapter is capable of fast charging Apple Watch. They are easily found on Amazon for example and at very good prices. But I would always recommend recognized brands. the isSpecifications that Apple indicates are valid are as follows:

  • USB-C power adapter Apple 18W, 20W, 29W, 30W, 61W, 87W, or 96W.
  • A comparable USB-C power adapter from another manufacturer that supports USB Power Delivery (USB-PD) of 5 W or higher.
