That one seems to be a US plug but I'm sure there are UK versions.
I got one of these to run our 2 air fryers and bean to cup machine.

Nice and low profile, no lead trailing around and doesn't block the other socket of a double.
Why two air fryers? We first got a Ninja Foodie 5.2L combi one that does steaming as well but it was a pain in the arse frying stuff like sausage and chips for 2 adults and 2 hungry teens. It would do it but took as long as the fan oven did, and food needed to be shaken and moved round every few minutes or it wouldn't all brown. So I got a cheap Scoville 4.7L one from Asda in an offer, about 40 quid. That's the dedicated spud machine (chips or roastie). In hindsight I should have got a big 2 drawer jobbie, but that will wait until I replace one or both.
I love doing hand cut chunky chips. Maris Piper spuds ideally. Leave skins on. Soak in water after cutting for 15 mins to get rid of excess starch, then a good rinse and pat them dry. Shake in a little oil, add salt and pepper and then 15-16 min at 200. Couple of shakes during cooking and they're nearly as good as my Mum used to do in the old chip pan.
