I wanted to share this opinion on Hackaday about a topic that is the usefulness of a something that has become ubiquitous relatively fast.

This techonolgyy has a lot of potential, what do you think?

    Lots of small kitchen appliances would be out of luck. Or how about vacuum cleaners as an example that needs a lot of power but might be plugged in for every room …. Where would I recharge batteries for my lawn care equipment?

      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

        One of the things you’re missing about USB and would likely lose here is that it’s “smart”. Both sides negotiate an acceptable power profile. If you only have one converter for the house I don’t think you could easily deliver many different power profiles to many points

          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.
