I’ve got a couple of Zigbee plugs, all work well, except one I use for the washing machine. It randomly turns off. When I check the history in HA, it just says that it turns off, no source. My guess is that it trips, ie temporarily exceeds 10A. The plugs are rated 10A from Aliexpress.
I don’t know if it’s true for cheap ones off Ali Express, but I always look for “appliance” plugs, as that will be easily searchable. Usually it means a 20a (in US) rated relay.

I have a set of halogen lights that’s pretty much at the threshold for common smart switches/receptacles/plugs, so used an “appliance switch” with a 20a rated relay, so I never head to worry about it. It’s really not worth going cheap for things that plug in
