Again, here in the US we use what I consider to be a sensible-size plug for 120 VAC.
I do not preach to other countries what plugs they should use on their power distribution.
I have considered what small appliances are probably unsuitable for USB-level power connections.
Besides kitchen appliances, we have a hair dryer, a good vacuum cleaner, and a good audio system (not a handheld device for compressed files and earbuds).
TV sets larger than our modest flat-panel can pull from 75 to 120 W when operating, while a reasonable computer monitor draws maybe 55 W.
In the kitchen, a full-size refrigerator pulls 350 to 780 W when running. With a wall plug, it is easy to replace when needed.
Similarly, a dishwasher pulls over 1 kW when running: batteries not included.
Also, consider my drill press: they range from 300 to 1000 W for reasonable sizes.
Furthermore, table saw, and soldering station are examples of plug-in tools.
You may like USB-style connectors: be sure to make them easy to replace if abused, but remember what else you need to power.
