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.
USB-C is limited to 48 VDC. Above about 50V, electrical safety codes apply.
A full sized European electric kettle is about 2000 watts, but if you limit capacity to a single cup you can get acceptable performance on 200 watt. A USB-C coffee pot or kettle scaled to 0.2 liters (7oz) could work. Would be a great option for travel
Toasters are frequently only ~750W. That isn't an order of magnitude away from the capabilities of current USB-C.
I doubt they'll ever increase the voltage beyond the current 48V (I was actually shocked that they didn't stop at 24V) so toasters are forever away. But not an order of magnitude away!
