Does anyone have a source for the available power at the usb-a port?
And what voltage and current is supported by the usb-c port?
I mean the power is right there

In case anyone besides me is interested, the 2022 Air's front USB-C port can supply up to 21 watts: 8.4 volts at 2.5 amps. This is into a laptop that could otherwise accept up to 50W charging power through its USB-C port.
