    Hi all posted before regarding 240 power use and wild camping.Just seen the item in above link and wondered what all u in the know think about it.Would this an invertor and a 110 battery be sufficient to survive in the wilds or can u see any drawbacks.Only want power for lights and telly for the kids,no microwave hair dryer or such

    it will do the job but for similar money you could buy a proper 230v generator and have the best of both worlds....230v inverter power (clean power) and the ability to charge your battery via your onboard charger.

    very much over priced for what it is and this 'generator' will be quite noisy as well, as it has no sound deadening cover to 'quieten' the engine.

    and for that sort of money i would expect a Honda engine......not a cheaper copy.

    Thanks for your reply papa John ,I have an autotrail apache so limited storage space does the genny u mention come in suitcase style. The thing that I liked the look of was the charging time quoted ,thus not having to have a genny chained to the van for long periods of time.

    yes, they are all suitcase models....which is more than can be said for the one in your link.......that is just a small generator.

    These (HERE) are all suitcase gennies...they look a bit like a suitcase.

    just to charge batteries and run a TV you only need a little one........1kw maybe.

    He is using a marketing trick there. No one in their right mind would plug a 240V sine wave generator directly to the battery when the 240V output gives a lot more power and uses the 3 or 4 stage on board charger.

    This is the genny I bought and I plug it into the EHU socket on the side of my van. Rather than an alternator which can't fully charge a battery it goes into my 25amp 3 stage charger.

    I will probably upgrade this to a Sterling 50Amp 4 stage charger.

    My batteries are in a storage area that is a pain to get to. This device would be seriously difficult to connect to my batteries. Where as my genny sits outside and plugs via a short EHU lead to the socket on the side of my van.

    Please note a battery should not be charged faster than 20% of its capacity.
    If you have a 110AH battery this is 22Amps. Doing it faster than this will result in boiling of the electrolyte and a reduced lifespan.

    Either this device won't charge your batteries at its advertised 50Amp rate in which case whats the point. Or if it does charge at 50Amps it will damage your batteries. I think the seller is using marketing speak to confuse people.

    If your on board charger can't charge at the full rate your batteries are capable of being charged at money spent on a better charger would be better spent.

    I am not knocking Chris Green who is a huge fan of these devices having built a few. I just think that at this price they are extremely expensive and won't fulfill their promise.

    My personal view is that a proper generator and an upgraded on board charger is a much wiser spend.

    Hi my blog will be updated in a day or two to show the install. My set up consists of two 110 amp batteries, an 80w solar panel and my b2b charger. I also have a Honda eu10i Genny that will rarely now be used. Contrary to belief the b2b 4 stage charger actually conditions the batteries..

    Welcome to the world of power quest :Smile:

    Hi, I would say the Honda eu20i as this has a 5 year guarantee and this thing has only 1 year, also this is only a battery charger not a Generator, with the Honda, you can run the battery charger, run all the lights you want to, use most appliances, ie hair dryer, microwave, electric travel kettle and most things that require up to about 1800 watts of power, and you will never be without power ever, but this thing only charges your battery, that can only run lights and tv and maybe an inverter for very small things, all i can say is that penny wise is pound foolish in this case (with all due respect) the Honda is king with me, although i have solar power as well and very good it is to, i love the backup that my Gennie gives me, and have you thought about all the gizmo's that the kids will want maybe on a rainy day, ie play stations, computers etc, all power hungry machines that will knock out your battery in no time, as you have to be very sparse with your power consumption with only 1 battery as a computer needs about 3.5 amps per hour output to recharge it for about 3/4 hours and this will knock any battery. Honda is KING and they hold there price very well, Regards Garry Flatpackchicken

    got to agree with grommet.

    the seller is relying on confusion....

    all small gennies with an additional 12v output function are around 8amp@12v and should be run at full throttle. so his comparison to other generators only point to 12v operation.
    run the gennies on 12v and you are wasting the 230v it is still producing...his cant produce 230v so no true comparison.

    using a genny at 230v, your onboard charger will do the job and the gennies 'smart throttle' will keep revs very low just charging.

    a 'smart throttle' regulates the engine speed and torque depending on the load imposed....light loads = low engine speed and low torque, and importantly..lower noise......heavy loads = higher speed and more torque.

    the 'SUPER-CHARGER' will only produce 50amps if your battery is completely flat and run at full speed all the time.
    as the battery charges up the amps will reduce to just 1 or 2 ....no different to your onboard charger.
    if you discharge the battery to 50% (recommended minimum) it will charge at maybe 20a/25a reducing to a trickle at full charge....again, no different to what your onboard charger does now.

    you could add a second battery and solar panal for much less than that. A generator uses about 1/2- 1 litre an hour at £1.40 per litre work out the running cost for yourself. We have the TV on 6 hours a day every day and never run out of power, don't carry a genny or stay on sites.

    I have just re-read his page and I am pretty angry at his blatent marketing ^&%it.. I am toning myself down to avoid getting Jim involved in a slander accusation..


    If you were charge a 70AH battery at 50Amps you would knacker it.
    This battery should be charged at no more than 14Amps on a regular basis. For a one off you could maybe get away with 17Amps.


    It is my opinion that either his figures are wrong and he is misleading potential purchasers or his device will damage batteries....

    I paid £80 for mine. It is an Amperor. I can't find the 25Amp one on sale at the moment only the 18Amp.

    The one I am looking to upgrade to is a really expensive 50Amp one by sterling.

    I currently have 2 x 250Amp VRLA batteries which are now about 5 years old and still going very strong. They are about 50% heavier than equivelent batteries due to their huge plates... They are built to take abuse but I look after them.

    I also have a 50Amp Sterling B2B charger and 240Watts of solar panels.

    The B2B charger is great if you are moving regularly. The solar panels are great if you are stuck in one place for weeks at a time and have good weather. The Genny and high capacity charger are great when everything else fails.

    I must point out that I am a heavy power user due to work... However I can usually go about a week off hookup..

    This is the charger I am looking at
