    Hi Funsters,
    this isn't a motorhome question but I'm sure someone out there can help -
    I have just installed a 13amp socket with USB charger.
    After I plugged in a 'phone and an iPad I noticed it buzzed and got quite hot - hotter than I would have expected. The ordinary plug-in USB chargers don't seem to get hot.
    Is this to be expected or should I maybe take it back?
    The socket is from Screfix and is BG (British General).

    I have installed several of these around the house. None buzz or get hot. I think I'd contact screwfix (I've always found them very customer friendly)

    I think they are the future rather than plug in chargers.

    iPads & iPhones take a higher charging current than most USB devices, the standard for USB outlets on a computer is 500ma, Ipad & iPhones need a 1amp charger.
    If the the USB outputs are built to the standard they won't cope with charging an ipad. Nothing wrong with the socket just iPads & iPhones not conforming to the standard.
    You need to find one with at least 1 amp output on the USB sockets. If the ones you brought are at least 1 amp you probably have a faulty one.

    I have looked at them but decided against them, as we are away more it would be something else powered up permanently another fire risk in the house.

    I have seen these for sale and wonder why anybody would bother to change, if doing a full room change then it might make sense, but why not just plug in the adaptor? even it that means using a multi plug

    As for your fault, I would get it checked or changed, could it just be a loose connection when fitted rather than a component issue

    • We use this, from Argos, in the house and in the MH.
    • Good little gizmo, does the job.

    I don't. A socket will last 100 years. The complex tiny charger circuit, crammed in, might well not survive the first thunder storm or electrically noisy old vacuum cleaner.

    I have something that looks like that, off ebay, but it has 4 sockets and 4 indicator LEDs. Great and only a fiver or so.

    Ours are supposed to be 2.1 amp shared over two USB outlets. I would not charge ipad and iphone at the same time, too close to the max load. They do charge one unit fine with no heat or buzz.

    I think I would send the unit you have back and get a replacement. They should not get hot or buzz.

    It is a motorhome question because we have several of them in our van :)
    Iphones and some of our tablets charge slowly but none of the sockets get warm or buzz.
    Sounds dodgy!

    You rated the above post as "funny".
    Something we don't know?
    Curious, that's all.

    I've had a few of these installed around the house for a while & have had not trouble. Certainly not getting hot or making noises.

    Thanks for the replies, guys.
    I phoned the company BG help line and their comments were worse than useless. They suggested that they can get hot and the buzzing could be from somewhere else, resonating through the socket - where did they find the bloke? Do they even pay him? He even spoke English - proper English!!o_O
    I think I will take them back and use an adaptor like johnp10 suggested(y)

    If you are using it to charge Samsung phones or tablets they draw up to 2 amps for fast charging. I burnt out a usb charger designed for an iPhone in no time at all.

    I have just read the leaflet that came with the socket. It says it delivers 2.1A divided between the two USB sockets, so I was overloading it, hence the heat! But buzzing?
    And why couldn't the guy from technical support have told me this?
    And why are they making something like this that doesn't properly support ALL common devices?

    The issue seems to be that USB connections & chargers run at different rates & amperages. Its totally weird, you'd need a slide rule & a ready re conner to know which ones to use.

    Then you come across two different types of USB connectors on some PCs etc. My notebook has two different types, an old type & a new type apparently. The difference is the speed of data transfer!!
