    I want to be able to charge my iPhone or iPad when I am wild camping or not on a site with electrical hook up. The cigarette lighter type sockets in the van dashboard will do the job while we are on the move but not when the ignition is switched off.

    I currently have a 12v socket in the van, with a remote switch, , which holds a twin pin plug, which was designed to power a TV and I want to convert that to a double USB socket. I appreciate i could just wire a twin cigarette lighter type socket into it but it's not very elegant. Does anyone know of a reasonable looking twin USB socket which I could use for this purpose? There seem to be plenty of 240v sockets round with USB sockets built in but nothing for a 12v feed.

    I fitted one last year and it has been a great success, I may fit another three, one for each corner! Go for USB 2.0 or above if you can, as they provide more current.

    I fitted the one in my pic, above, to my car.....saves having those awful plug-in things hanging out the fag lighter which is part of the ashtray and normally closed.

    One of the best mods i have done.

    Did wonder if the cheap versions actually supply 5v to the USB when engine is running and feeding battery upwards of 13.8v In my feeble attempts to check I saw off a few fuses and am none the wiser?

    The linked to by @NickNic has an input voltage range of 12 to 24 volts. I haven't looked at the other one. So I guess you just need to check when buying one it has this sort of range.

    Doh! Just re-read the OP and realised it was for wild camping and actually says withou EHU. Never mind, it still applies.

    I fitted one of these, my battery is normally very good, didn't use the MH for about 3/4 weeks, flat battery. IT seems they use power all the time. I am just now fitting an on/off switch. I guess They are fine if you use the camper often......or it's just mine. :)

    Ralph's gone overkill with the blooming things in the PVC.
    One each side in U shape lounge overhead cupboards ( charging while traveling so things don't slide about) .
    One each side under overhead cupboards To use whilst lounging.
    One in kitchen area.
    One in cab. So six In total !
    There's only two of us now not five. :BigGrin:
    He does like his gadgets though.

    I can't honestly say I've had a voltmeter anywhere near it. What I can confirm though is that when the engine is running there's a nice blue light on the USB socket and it charges my phone which is what it's there for (y)

    They do - the little blue neon. Mine's connected to an ignition live not a permanent live so it's isolated when the engine is off.

    Get the right one. The ones on ebay vary considerably with their output. They all give 5volt but output varies from .5 amps to 2.3 amps. Basically a four fold difference in charging time. Or perhaps more importantly something like a tablet used for navigation could be discharging faster than charging if you choose an output too small.

    After finding the ones that I originally fitted were 1.2 amps and could't keep up with the tablet screen I changed them for 2amps ones fine now. As far as I know the higher amperages will not harm anything

    I did similar in our PVC, fitted about 5 USBs and an extra 4 240v, maybe a little overkill but its always handy to have power at all ends of the van i think, am just doing the sam now with our Hobby - only problem is they take a couple of wweks to arrive from China, just cant understand why british sellers want so much for the same thing - less than a few pounds with free postage from china - have seen the same thing from UK sellers for as much as £17 each, would rather wait 2 weeks, especially when buying about 7 items :LOL::LOL:
