Hi there, I have been using the Belkin 3-in-1 charging station (https://www.belkin.com/us/chargers/...wireless-charger-with-magsafe-15w/p/p-wiz009/) to charge my iPhone/Apple Watch/AirPods but I recently upgraded to Apple Watch 7 and want to take advantage of fast charging. I love my Belkin station but it does not support fast charging of my Apple Watch 7. Does anyone know of a nice charging station which basically just provides the 'skeleton' where I can fit an original MagSafe charger as well as the new Apple Watch 7 charging cable?
 
Can anyone recommend a dual charger that can fast charge AW and iPhone (MagSafe). Ideally one with a cord (no Wallplug).

If you're talking about a charger that would be plugged into a computer, I'm pretty sure that won't work and you'll need a wall plug—since the MagSafe fast charging is 15w and requires a 20w adapter minimum. That's not including the Watch requirements, and is higher than any computer port's output of which I'm aware—Thunderbolt 3 or 4 are usually 15w.

Sorry, no native speaker so maybe I stated this a little strange. Was thinking of a power adapter that has three cords: two to the devices (AW and iPhone MagSafe) and one to the power outlet as I want to fit the stand into a shelf and the position is farther than one meter from a power outlet.
Did not find something adequate and so I bought a power adapter from Anker (Powerport III duo) with 2 PD ports that both deliver 20W. And bought an additional extension cord from adapter to power outlet.

No problem!

While the Powerport III Duo should work fine with the MagSafe charging puck, it will likely charge at a maximum of about 13w—not the full 15w.

That's because on their spec page for the product, it shows that it outputs 9V-2A (18w)—while to charge at the full 15w, the MagSafe needs an adapter that puts out 9V-2.22A (20w). That's a new spec: 20W Power Delivery 3.0

There's an article about the adapter requirements here:


And there may be some 3rd-party adapters that put out the full 20W as 9V-2.22A, such as:


https://us.anker.com/products/a2038 (this is the same as above, but with 2 identical outputs)

And cheaper ones:


The Watch Series 7 requires a minimum of 5w PD, according to this:


But all that said, I have to say that I don't see a huge difference between using MagSafe on an 18w v. 20w adapter—when charging the iPhone, it really only hits the peak charging speed for part of the charge, and I'd be curious to see the actual difference between 13w v. 15w for a full charge. It's more likely to boost things when going from 0-50% or so. These people found less than 5 minutes difference:


And if you're really in a rush to charge your iPhone, you're not going to use MagSafe anyhow: a Lighting cable will be under an hour from 0-80% — more than twice as fast!

Hope that helps!
