    I am curious? I have been looking at electric cool boxes and they say 12v and 24v, 24 being 240 so does 12v mean 120v in so far as if I bought stuff in the US when I go will it be suitable for use in the MH with a plug change? If so my purse has gone into hiding.

    What ever makes you think it is 240v? I would have thought it is 24v, as found in some lorries I believe.

    do you have a link to one you refer.. ?

    they are normally 12vDC , some come with a power adapter for mains 240v AC

    If buying to use in the van it can only be used when you are driving otherwise it will flatten the battery in no time..

    If it has an 240v power adapter, you can of course use on EHU.

    If both voltages can be used, typically the blurb will say ..
    • 12V and 230V compatible

    Your purse has the right idea.......
    If you cant buy anything then you will remain safe.

    12v and 24v are battery voltages
    240v and 120v are mains voltages.

    American goods.......no good whatsoever if you don't have 120v mains in your van, no matter what kind of plug you fit.

    2 of my 12v sockets are apparently the old narrow ones and if US stuff would work it might have been worth upgrading them so now I need to re-think about whether it is worth it as there doesn't seem to be much 12v stuff around

    THE 12/24 will relate to DC (battery) voltage..
    As already said it will be so people know they can also be used within trucks as they are mostly 24v..

    It was a Halfords one and it is 12v and 240 compatible but as it needs EHU it would only be of use on campsites so I need to think if I would get enough use to warrant the spend. It is still early days for me and a whole lot to learn. Thanks.

    So in essence when wild camping 12v is just for TV, lighting and water pump/heating?

    By "old narrow ones" do you mean a Hella socket, which are like a small cigar lighter socket? If they are they are much better than cigar lighter ones.

    My Dometic cool box comes with a lead which can be used in both types of socket, there is a red bit on the plug which comes off so it can be used in a Hella.

    I don't know what you mean by not much 12v around. There are lots of 12v cool boxes about and there are three main types of cool box. Gas ones, which can't be used in the vehicle, then there are the thermo-electric ones. These are probably the most common with prices ranging up to about £100. They are not particularly efficient and typically will only cool to around 18°C below ambient so if it won't gets things very cold when it's really hot. Finally, there are the compressor types for which you can expect to pay £300+ but they are very efficient in use of electricity and will chill and even freeze in high ambient temperatures. This is the type we have (Dometic/Waeco CDF 26) and it is superb.

    bit of a sweeping statement John.. plenty of 12v stuff that is excellent .. for example..

    I have a 12v Alden satellite dish and sat decoder.. ..not rubbish

    12v Garmin .. etc etc etc .... not rubbish..

    maybe your car runs on 240 v mains ? :LOL:

    12v Cool box.. yes, IMO.. they are indeed rubbish.. . may as well wrap the stuff up in wet newspaper..

    That was how the man in the shop referred to them I asked him about the red bit but he didn't seem to know. So no upgrade required just some good info and the cash saved in making a mistake can go toward a proper cool box if required. I have a small pink electric cool box I was given and when it was on I put the thermometer
    In it and noticed it didn't get very cool so was having second thoughts already so this gives clarity £300 + or none.
    did you get your inflatable awning are you pleased with it?

    AC/DC different things 12volts DC as in cars vans etc 24Volt DC as lorries and buses to allow higher current flow through same wire sizes for starting Etc..
    112 volts AC standard house wiring/ 220 volts for heavy circuits in USA
    240 volts AC in Europe Houses 415Volts 3phase for heavy loads in Europe.
    Transformer and rectifier to bring AC voltage to 12 volt DC for smaller appliances.
