You joke, but this is enough to make recharging an e-bike practical. E.g. https://amplerbikes.com/pages/nova

That's only a single ampre at standard European mains voltage. It's still a lot of power for those tiny connectors and insulation, but an order of magnitude insufficient for those appliances.

I bet that cable gets plenty hot at 200+ watts.

I remember scoffing years ago at USB powered coffee warmers. Maybe the situation has changed.

I mean my electric Fan and standing lamp are both powered by USB-C.

There are things that shouldn't be powered by USB-C. But there are plenty of sub 100W consumer electronics devices that really should be USB-C. I waited years before Panasonic released their lamdash shavers using USB-C.
