    The Zig CF8 of old had a problem. It would only charge a battery if the supply voltage was around 200v? or better. I tested the one I had, after a new battery failed to charge. In some countries campsite supply can be less than this and if you're at the wrong end of a long supply circuit then you could be doubly affected. I phoned the big cheese at Zig and he confirmed this was the case, he reckoned the unit was only intended for UK use, yeah of course it was!. Naturally their larger and more expensive unit would work if supply was 180v? or better.
    Voltage ? due to forgetting actual figs. The latest CF8 Zigs may have overcome this deficiency.

    e.g 60 watts of lights / 12 v would give a 5 amp draw .

    For fire risk as others have said thickness of the cable is important.

    Thanks so for example 60w of lights at 12v I'd need a 5 amp fuse ??

    fuses in the fuse box are there to blow before the wiring bursts into flames, ie they are sized to according to the size of wire installed in the fixed wiring..
    its the individual plug or outlet fuses that should be matched to the watage of the applience.

    Bare in mind that a fuse can take up to 3 times it's rated capacity before it melts and that's when things get
    warm, especially cables that are too small and poor connections, better to use circuit breakers.
