American battery charger....

    Hi all,

    Just a quick question. I bought a dewalt cordless impact driver from America and I'm wondering what do I need to be able to charge the batteries here in Ireland.

    I called into maplin and the lad there was on about a 500watt converter or something like that... He was on about multiplying the input, 120v by the output, 4ah to get the watts.... This is total jibberish to me.... Iv attached pics of the charger which might help.

    Many thanks in advance

    Martin

    Yer man is wrong because you have to stay on the input side with the figures here.

    You need a step-down transformer to convert the 230 V Irish mains supply to the Yank 120 V one. The frequencies are different (50 Hz here, vs, 60 Hz there), but this may not be important. (BTW, you might see 220V, 230 V, 240 V and 110 V, 115 V, 120 V mentioned, they're referring to the same thing respectively: European vs USA supply)

    Anyway, 120 V @ 1.5 A = 180 VA
    I haven't a notion what the power factor might be for the charger, but I think that a 250 W transformer should suffice, so that's what you're shopping for: a 250 W (or greater) step-down 230-120V transformer.

    The yellow "buckets" you might see trademen with for running their power tools would do the job, and are often 1000 W or more, but you'd need a plug shape converter then. $_80.JPG

    You can sometimes get those yellow transformers second hand at hire shops.
    Alternatively you could look at one of THESE from Maplin but I am not sure if they have enough current ?

    Actually This One has the current rating you would need, so if it was only the drill you were charging then it would suffice

    get a 230v version of the charger and keep that one for 110v places

    this might be the one - check with someone who knows
    approximately EUR 40.26
