Hi

I am currently using Apple’s 20w USB-C power adapter. Can I get faster charging with a different power adapter when using the MagSafe Duo? If so what Apple power adapter would be better? Thanks.

Apple recommends using the 20W adapter for best results, I’d stick with it.
Thanks. Is there any advantage, in terms of charging, to use a separate charging puck for the phone (12 pro) and a separate magnetic charging dock for the watch?

if I did that, I would lose the convenience of the MagSafe Duo. I mainly charge overnight, but not exclusively so.

No point in charging both devices separately, no point in having the duo charger then.

I’ve had the belkin 3-1 MagSafe charger for 8 month now, can’t fault it, great device.👌

You get a 45W adapter included in the box with the belkin 3-1 charger, if you can get a refund on the duo, highly recommend buying the 3-1 MagSafe charger.

Hey we are using that Belkin charger as well. Dry practical in my opinion

How big is the power adapter? Is it larger than the Apple 20W USB-C?

That won’t fit my outlet. Guess I will stay with the MagSafe Duo. Thanks.

I actually replaced my power outlet with Leviton’s dual usb c outlet. Took a few screwdrivers, and some electrical tape to switch it out. It’s 30W shared, so if you have just one port in use, you get the full 30W, so that’s what I have hooked up to my MagSafe duo. For other ways that don’t involve switching out your power outlets, Apple’s 30W adapter is best. Best Buy often has them on open box deals.

The 29W one will technically work, but it will only power one side, whichever side happens to connect to a device first, can’t charge both.

Weird. I understand that the 29W adapter is older; but 20W is enough for both sides, not 29W?

It has something to do with the power delivery I think. Something to do with the Volts that it can handle?

I think there's some youtube videos on it.

To summarize the article below:

"In order to eke out the faster 14W wireless charging speed, Apple says that a 30W power adapter (or higher) is required. In other words, to get the best performance out of the MagSafe Duo, you can end up spending as much as $178 when coupled with Apple’s $49.00 30W USB-C power adapter. For those that don’t care about the fastest speeds, Apple’s $19.00 20W USB-C Power Adapter will yield you speeds up to 11W."

I care about charging speeds, that’s why I’m using the $19 Apple 20W charging brick which gives me the maximum charging speeds when using an USB-C to Lightning cable. Anything else is overkill and a huge waste of money, imo.

You need the Apple 30W charger to get the max charging speed, the 20W only charges at 11W...

I realise that this is about MagSafe (which I personally think is a gimmick), but the best way to charge a newer iPhone at maximum speed is by using the official 20W Apple charger (wired). Only the 12 mini is limited to 12W when using MagSafe (no such limitations when using a USB-C to Lightning cable instead). The other models are limited to 15W when using MagSafe (regardless if you use 20W or 30W). The watch has a tiny battery and won’t benefit from that 30W brick at all.
