is 12 volt ok with respect to needing 20 watts?
20 watts is needed to charge an i phone 13 mini, does 12 volt power plug meet this requirement?
Question marked as
It doesn't need 20 watts. That's the maximum input power it will take, but less than that will still work.
The 20W Apple USB-C power adapter puts out a maximum 15W (5V x 3A) at 5V, or 20W (9V x 2.33A) at 9V. Almost all USB-C power supplies have stepped voltages, like a 30W MacBook Air power adapters has 20/15/9/5V. If you're using something like a 12V lighter adapter, it may or may not put out 20W. But if it doesn't, it shouldn't be a problem. More than likely it would be stepping down to 9V, although one could be designed for a specific maximum current.
