Electrical Appliance Wattage when on EHU?

[Captain Caveman]

Hi guys, apologies in advance, this is probably a stupid question from a total newbie!

Does anyone know how to work out the maximum possible appliance wattage that can be used (say, an air fryer) in the van whilst it is hooked up on EHU on a campsite?

Does the campsite specify the maximum ampage of their EHU supply, e.g. 6A, 10A or whatever - and in that case can you work it out from there?

Or is it vehicle-specific/governed by the ring main fuse size?

We have an Adria Supersonic, but it doesn't come with much of a user manual!

I would still check the individual sockets for their limits. I've got several 240v sockets in the van, but they're labelled "max 4A".
You don't want to melt any wiring.

Many thanks, a very good/salient point, I shall check!

And that fórmula, P=IV, if you use, it shows why decent 12v hairdryers, kettles, etc aren't a thing.
For, say, a 1750w appliance ...
P=IV
P/V = I
1750/12 = 146 amps

P=IV! I should've remembered my O-Level Physics!

Talking about wifi, I bought a cheapo Huawei 4G portable router and stuck a Giff Gaff unlimited data SIM into it, instant wifi hotspot for streaming the van's TV, my laptop and all mobiles etc., worked really well. You only get around 10Mbs but that's enough to stream HD movies etc.
