Air fryers - are they too high powered?

You have (generally) 16 ampers available on site.   Your fryer runs in your home on a domestic socket that will be rated at 13 ampers, so there is a wee bit left over on site for other kit. 

There should be a plate on the underside of the fryer that shows the power consumption in watts.  Just divide that figure by 240 to get the approximate amperes that it uses. 

We used the oven almost every day for average 45 mins and a bottle of gas would last 2years+. Equate that cost with buying electric cooking equipment. The gas oven is there and my choice is to use it for its intended purpose.

Also remember that running electric cooking items may mean not using your heating, hot water, kettle, microwave etc.

The Ninja Foodi Dual Zone Air Fryer, which is probably one of the larger air fryers is 2400 watts, or just over 10 amps just as a reference point.

We often use a small electric fan oven/grill, as we find our gas oven difficult to get on with.   Top shelf food is frazzled while bottom shelf food is only part  cooked.  It also makes the van very hot in summer.

The oven was originally £25 from Lidl but I think they may now be £35.   Plenty of places sell them, but this one has a decent capacity.

It uses 1300watts in total,  but you can use the bottom heat alone or the grill alone if you wish. It takes 2 shelves, so quite roomy, and is not particularly heavy.

We also have an electric cooking pot which is good for pasta dishes and frying too, it uses 1250watts.

As KjellNN, we used a small portable electric oven for many years, originally from a French supermarket and about 1400 watt it served us well when we had the boys with us.

I'm now a Remoska convert which run at 480 watts, 2 amps, for the 2L version. I was originally sceptical but I have not really found anything thy will not cook, with the only exception of very crispy roast veg. Yes they are expensive from Lakeland but bargains can be found on Gumtree, with one selling only yesterday for £35.

I presume that's why the OP wants an air fryer, crispy chips etc. Occasionally I take some oven chips and do them in the gas oven but if you're a chip aficionado air fryers are a better bet.

Check the wattage on the box or rating plate divide by 240 that will give the current, our air fryer at home is 1300 watts so that will draw about 5,5 amps so would be no problem in the van, that's Ohms law and useful to know.

i use a Multicooker when away in the van, it works on 6 amps no bother, its 15000 watts at the highest setting. 

Wow, that's supernova territory. Must be hard not to burn stuff.

Ooops, think that should have been 1500 watts
