    Hi

    A 1kw would do the job quite adequately .. but it may be worth going up to a 2kw which would give a bit of spare capacity for any other things you might want to run in the future.

    I have a 2kw Honda EU20i it's quiet and very reliable with a 5 year warranty and although they are probable the most expensive are worth the premium if you intend to use it a lot.. highly recommend it.

    A good selection here ..
    Honda generators at Edge Technology: + pramac,sdmo,stephill

    If it's only for occasional or emergency use then go for a cheaper make..

    Please forgive my extremely embarrassing ignorance in asking this question. How do you connect the generator to your motorhome if you want to use it to charge your battery. Does it work as if you were using a set of jump leads and, if so, would the leads come with the generator? How long would it normally take to charge up a run-down battery? Are there any safety issues I should be aware of in terms of carrying around a petrol-driven generator? What type of fuel do most generators use?

    I am going to a few festivals this summer, a couple of which involve 4 nights camping without hook-up, and I am rather concerned that the battery won't last the distance. I feel a complete prat showing my ignorance like this, so please treat me gently and use language that a technophobe would understand!

    squeezy and grace,

    grace.....my advise would be buy the biggest you can afford......a bigger genny (2kw)running at a lower speed will be quieter and more fuel efficient than a small one (1kw) revving its nuts off plus you never know what you might want to run off it in future.
    a low wattage (750/800w 230v kettle wont leave a lot spare with a 1kw genny.

    squeezy.....if you just want to keep the battery topped up while wild camping /on site without hookup then connect it as you would your hookup lead.
    this way you can use any 230v appliances, TV etc at the same time as charging your battery.
    your onboard charger will have a higher output (maybe 12/15amps)than the gennies battery charging facility (usually around 7amps) so will charge the battery quicker.

    if you want to charge your engine battery alone then use the supplied leads as you would a normal charger.

    hi, if you knew the answer you would not have asked the question!!!!!!!
    If you are only away from EHU for 4 days at a time in the summer you may be able to manage on your batteries, it depends what you "must" run, solar panels will keep you running when the weather is bright. If you intend to use the van in the winter, or use a lot of power then a genny is really the only option to remain working IMHO. We run a 2.7kw kipor but unless we "have" to run air-con this is too much weight to carry around, if we were to change it now we would get a 1kw, and when off EHU just use 12volt equipment.
    But we are all different and you must decide what suits your requirements:Rofl1::Rofl1:

    PS we have just removed a 6.5kw genny because we never used it!!!!!!!

    If that's all you need to power up then a 1 kw. will suffice. Stick to a 4 stroke one and you wont go far wrong. As has been said, Hondas are probably the best but Kipor are good value and unless you intend using it a lot would do the job very well and should last many years.

    To answer the last part of your question. If you have a 100Ah battery and you run it down say to 40% of its nominal capacity then you need to replace 60Ah. If you have a 15 amp three stage battery charger, then to go through the full cycle of bulk charge and absorption sequence might take 6 hours (and a deep desire to make enemies of your fellow campers) depending on the settings.
