Does it work with? How faster is the charging using MagSafe Duo Charger with 30W power adapter charging only the iPhone 12 (scenario 1) and both iPhone 12 and Apple Watch series 6 (scenario 2)?
Apple Watch Series 6, watchOS 7
The charge rate is determined by the phone; when you plug in a device the device “negotiates” the voltage and current it wants. A 30 watt charger will not be faster than a 20 watt, but there is no harm in using it. You could also use a 61 watt MacBook charger, but again, it would not be any faster. And you can use the 30 watt for any other Apple devices such as your Apple watch, AirPods, etc. One thing to note; the MagSafe wireless charger is limited to 15 watts, but plugged in it can charge at 20 watts. So using a cable will be faster than wireless charging.
All Apple power sources and cables are cross-compatible as long as the connector fits without forcing. Obviously, a lower power source will be slower, but it will still work.

You can use the 30W power adapter, but it won’t be any faster than the Apple 20W adapter, and if it is not a USB-C/PD adapter it may be slower. Just make sure the adapter is certified as Made for iPhone if it is not an Apple product.
Dear Lawrence, thank you so much!!
Dear Lawrence, thank you for your prompt reply. My 30W power adapter is an Apple one. Do you know if it will work faster the 20W or even the same power delivery OR it will charge my iPhone 12 and Apple Watch series 6 slower than using the 20W charger. The ideia is to use the faster with no damage to the power system or devices.
