Comment on USB-PD is a de-facto low-power DC voltage standard, with USB-C being the universal plug. Hurray!

What?
Most vaccums are brushless, where they are already converting the AC to DC internally. Your vacuums would be cheaper.
Where would I recharge batteries for my lawn care equipment?
again what? The same way? Your charger is converting AC to DC. You could skip that step.
All of these appliances would work better/cheaper with a 110VDC@15A source.

Yeah I think many of us missed that you’re proposing a full power replacement circuit, rather than USB power everywhere

You wouldn't have to.
Every device instead of having an expensive PD communication device in it, would have an even cheaper PWM DC Step-down.
No communication needed.
Each device would just draw what it needs to.
