USB-C charging specifications for 2020 MacBook Air

I was wondering what the power/charging specifications are for the two USB-C ports in the 2020 MacBook Air. For instance are these ports USB-C power delivery ports? Are they able to fast charge an iPhone 11 like the 18 W apple USB-C adapter can?

MacBook Air 13″, macOS 11.0

Fast Charge through macbook pro plug? I have just bought a fast charge cable for my iphone 11 but need to now get a fast charge plug. I wondered however whether the plug for my Macbook Pro would work as a fast charge plug at all or if I need to buy one. Thanks!

How much power does USB-C on MacBook Pro 13" (2020) deliver? Hi! I have - as the title says - the question of how much power (Watts) the MacBook Pro 13" 2020 (4 Ports) delivers (or can deliver) to connected devices. Specifically Id like to know if I can charge my iPhone 18W when I am connecting it to the MacBook Pro instead of the 18W charger (using the official USB-C charging Cable) Now I have tried to use systeminfo to get to this information, but Im not sure if I am correct with it: 1) Systeminfo -> Hardware -> USB -> USB 3.1 Bus shows this (translated from german to english): Available amperage (mA): 500 Amperage required (mA): 500 Additional operating amperage (mA): 1900 Standymode amperage (mA): 2400 -> So in total it can deliver up to 2,4 Amps - right? 2) How much Volts can it deliver, though? Systeminfo -> Hardware -> Power shows for the battery a voltage of 12829 mV = 12,8V Since Watts is Amps x Volt this would make ~30 Watts, but that is for the battery in general, not specific to one port. - - - - - - - - - - - - - So how much Wattage can the MacBook Pro deliver with one port or per USB Bus? Can I fast charge my iPhone with 18 Watts over USB from the MacBook? Is it depended on wether or not I charge the MacBook. Is the info above from systeminfo even useful? Even one of those questions answered would help! Greetings, Sam

Thanks for the response Kappy. So are you saying that, for instance, if the 30 W adapter that came with my MacBook is plugged into one of the USB-C ports, the second port will be able to provide up to 30 W of power to charge another device? If that's correct, how much power would the USB-C ports be able to provide if the MacBook was running on battery?

A USB-C port can deliver up to 5A or 100 watts. They can fast charge an iPhone 11. This may be limited by the charger that is being used.
