Possibly daft electricity supply question

[DontCallMeBaby]

We are going for the first time on Friday, got the basic kit all ready to go, and nice long packing list in a spreadsheet. :) But I keep coming back to worrying about pumping up the airbeds - we have an electric pump, which I must make sure actually works with the airbeds (it was originally bought for the likes of ballpits and paddling pools) but I have this horror that it won't work on site. We have electricity at the pitch, but is it going to be of a conventional three-pin-plug variety? Or some exotic camping variety?

Do you have an EHU? If you have an electric pitch, you need an electric hook up

similar to this

hookup

Can get cheaper. I have this one.

You then plug EHU item into electric point on pitch and have the sockets in your tent IYSWIM.

Also, you only have a certain amount of volts, and most conventional home items will blow it. Eg chargers, and prob pumps are fine, home kettle + hairdryer may blow it. Travel items have low watts.

Aha! DH was talking about something like that, but we definitely need to find cheaper. So the round blue three-pin-but-not-the-usual-three-pin thing is what I'm looking for ... it does look familiar, from back in the days when I had parents to look after such things for me!

Ooh electrically-knowledgeable people - do I need an adaptor to use an EHU in Denmark? have borrowed one, never used one before, know nothing!
