Any speculation or even actual knowledge on how fast existing 3rd party chargers like the Belkin Boost or their 3-in-1 will perform with the Series 7?
 
I would like to know this as well. But my expectation is that current certified accessories won’t charge the series 7 faster as they are based on Apple‘s previous specs.

I’m thinking the same…which sucks. Was just about to buy a new 3-in-1 charger. Guess I need to hold off which means still competing for the 1 we currently have.

Exactly in the same situation. Just got an iPhone 13 Pro and tempted by the Belkin 3 in 1 MagSafe charger, but I’m planning to get the series 7 and if I’m buying a fancy new charger I want to be sure it can leverage fast charging.

Actually fast charging the watch is more important than fast charging the phone to me, as the watch is on the charger for a short time before I go to bed, while the phone is sitting there overnight.

Bought 2 Belkin charger… 3 in 1 for bedroom and 2 in 1 for home office. Im pretty sure fast charging will not be supported on those. They need to put out a new model.
 
I think you need the new USB-C cable/magnet and (I'm hoping any) >=20W USB-C charging brick. I have a 27W USB-C wall-plug that I'm going to try with it. Pre-ordering the series 7 tomorrow and will follow up here if 3rd party chargers will fast-charge something like 0-80% in 45 minutes. I've got an 18W car charger that I intend to test as well. If they don't work as well as I need to then I suppose I'll have to go the  store and pick up an OEM 20W as well as check out a few new watch bands.

Yes I would be quite confident that any USBC wall charger which is powerful enough will provide fast charging when combined with Apple’s new charging puck.

Thing is I really dislike those charging pucks because they bring one more loose cable on my bedside table. Much prefer an integrated charging docks which can take care of my phone, EarPods and watch with only a single cable. Hopefully Apple will quickly let dock manufacturers integrate MFI watch chargers with fast charging.

I have a 27W USB-C charger with USB Power Delivery that appears to fast charge my  Watch Series 7. It seems that USB Power Delivery is required for fast charging. Haven't had the need or opportunity to try it on my 18W car charger but I assume it will work just fine as it also has that feature. Battery life is pretty nice, but of course it is brand new; and it does charge pretty quickly, though I haven't used any other smart watch before.

More info here!
 
Fast charging requires the new (aluminum shell) charging puck and an AC adapter that is 18W or greater with USB-C PD.

Correcting what I wrote below: Apple's support document says that the old 29W adapter will fast-charge the S7 watches if you use the new charging puck. Quote from the support document:

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

As an example of a +18W AC adapter that won't work, the Apple 29W adapter that was supplied with the 12" MacBooks for several years is not PD compliant and probably won't fast-charge a Series 7 watch. I say "probably" because I don't know exactly what power rules the new charging puck and S7 watches need the adapter to comply with. The 30W adapter provides 5V @ 3A, 9V @ 3A, 15V @ 2A, and 20V @ 1.5A and will definitely work. The 29W adapter provided only 5.2V @ 2.4A, and 14.5V @ 2A (and didn't comply with either USB-C PD 2.0 or 3.0). That's why the 29W adapter doesn't work with the MagSafe Duo charger. <-- That statement was correct, however.
