Will Uniross Ultra Fast Charger Work In USA

    I've just purchased a Uniross Ultra Fast Charger from Jessops and
    although they assured me it would work in the USA (with a three pin
    to two pin adaptor), i'm not entirely convinced.

    I've searched for info on the web and also paid a visit to the Uniross
    web site (www.uniross-batteries.co.uk) but I can't seem to find any
    conclusive answers on this.

    My gut feeling is that I should take it back for a refund and then
    spend a little time looking for one that fits the bill.

    Does anyone know if this charger (model RC102235) will work in
    the USA exactly as it would in the UK?

    The mains adapter should state on the label what its input ratings are -
    if it says something like;
    "Input 110-240v 50-60Hz AC" then it should be fine.
    If it only says "240v 50Hz" then I don't think it will be. IIRC the US
    uses 115v 60Hz.

    Your choice in that case is to either return it, with appropriate harsh
    words relating to knowing their products, then buy elsewhere, or to seek
    an alternative mains adapter that is dual voltage input but with the
    same output rating as the one supplied. I suggest the former course of
    action will be easier.

    Cheers for the info dslr...

    The adaptor says - Input : AC230V 50Hz 15W

    No mention of 110v or 60Hz so I guess i'll be taking it back tomorrow.

    Oh, those frequently are "worldwide", but all the ones I've seen are
    boxes with a low voltage lead and a mains flex.

    The type I'm referring to are the (usually) cheap 'n' cheerful ones with
    a transformer built into an enlarged 3-pin plug.

    My mobile phone charger is exactly that (like most of them) and I know it
    works in the US via an adaptor. I've never checked to see what the official
    input voltage is though. Maybe it was only charging slowly? :)

    I think there could be weight-related problems using a larger unit of this
    type via a 2 pin adaptor though.

  6. I don't know this particular charger, but mains adapters/chargers that
    work happily on either 110V (US) or 230V (EU) are not uncommon. Mobile
    phone and laptop computer chargers are often of this type.

    Before you go back and thump the counter, have a careful look at the
    back of the charger. If it is for dual voltage, it will* say something
    like "Input 100-240V AC 50-60 Hz". If so, it's OK (the mains voltage in
    the USA is 110V 60 Hz, or of course zero on occasion, in which case you
    are out of luck anyway). If it says "Input 200-240V 50 Hz" then it's for
    Europe (or other areas with similar voltage) only, and you should indeed
    take it back as they have sold you something not fitted for the purpose
    you specified.

    * Not sure of the details, but I believe that all electrical equipment
    offered for sale in Europe is required by law to have such
    specifications clearly and permanently marked on it. The example of the
    wording on a dual-voltage device is copied from my laptop power unit,

    For a moment I thought you were being ultra-pedantic about the
    interpretation of "alternating current".

    Yes, I'm sure you're right about this. It should do exactly what it says on
    the label.

  8. Actually, I had not thought of that, it's quite good - except (being
    really pedantic) that the quoted voltage for AC is of course the RMS
    (root mean square) voltage, not the instantaneous voltage. I was of
    course referring to the recent outages and the antiquated/inadequate
    transmission system that caused it.

    Thanks to all that have replied (or commented) about the above...

    I returned the Uniross charger to the store and while I was there I noticed
    (slightly hidden
    from view) at the back of one of the racks was a sole Sony Super Quick
    Charger. This one
    is for world wide use (110v - 240v 50/60Hz) and comes with 4 x 2100 AA NiMH

    I'm quite a fan of Sony products so needless to say it's now in my

    Once again thanks for the words of wisdom...
