    looking again though? is it not just an alternator on an engine?

    I think the Green machine's patent has been nicked. :RollEyes:

    the seller is contradicting himself here......

    study the charging times, in particular the onboard charger times.....221 minutes.

    now read the bit in blue about using an inverter.....charge your battery in minutes not hours.

    unless you have a standalone high output charger you will be using your onboard charger via an inverter powered by the super charger.

    so......it will still take 221 minutes.


    it isnt possible to charge a battery in minutes without causing irrepairable damage.

    sounds to me like the seller knows nowt about charging technology.

    Err, Hmmm Guys and girls

    Yes it is an alternator, just like the one on your engine, just like the one on your engine that will run if you start the engine you already have:Eeek:

    Want to make yours a little better? use a hand throttle or a brick on the pedal.

    Change the wiring to a decent gauge and change the split charge relay to a good quality 150 amp jobby

    circa 40 amps on tick over!

    Or if you still have your genny, use a decent 50amp four stage charger to achieve the same results

    Agreed John. I was an Electrician/driver in the Royal Signals and spent a lot of time charging leasure batteries for the office wagons. Banks of 50 or more. You are absolutely correct, these things are ok in an emergency but regular use will as you say kill the batteries. :Blush:

    OK it,s an engine coupled to an alternator, so why will it damage the batteries if van alternator won't?

    Not really. To manufacture this 700W unit in the UK in small quantities costs loads.

    But in China, see Machine Mart, 1000W sinewave £286.

    They do have a 720W genny for £95, you could rip the 240 alternator off it and replace with a car 12V alternator/charger.

    What is wrong with the average MH use of a genny is the on board charger, just 20A, get a 50A charger and more of the gennie's output can be harnessed.

    The starter battery usually only discharges 1% (??) to start your vehicle so that 50A does not last long enough to heat up the battery and damage it.

    The batteries will not charge continually at 50 amps as the charge increases so the rate will decrease

    one good reason.....your van battery will be at least 99% charged all the time with regular use, so the alternator will only put in what is missing and will be regulated to a few amps, not 50amps.
    on the odd occasion it has gone flat it wont hurt to charge at 50amps (or more) as it is just an occasional charge.
    the battery is only there for one primary purpose...to start the engine.
    once running everything electrical is powered by the alternator with the battery absorbing and smoothing the output power.
    a battery is nothing more than a large , slow discharge capacitor.

    a 50% discharged leisure battery will take the full 50amps, reducing as it charges, but bunging 50amps at it time after time, every couple of days or so, wont do it any good at all.

    Yes, the sign states that the output from the 12volt Honda is about 8amp from memory.

    That is 8amp DC

    I will give you an example. I have just changed my motorhome, one of the first things that the workshop will be installing is a 2000w pure sine wave inverter/charger. The charger function is 100amps. Regulated, temperature controlled and monitored.

    So run a genny with the 12 volt battery charger connected it produces 8amps after one hour, or in my case run the genny for the same length of time and put nearer 100 amps into the battery bank!

    If you don't wish to overly complicate it simply buy a good quality 220VAC charger, plug the genny into your van, plug the charger into 220 VAC wall socket and hook up the battery!

    Or run the engine:Wink:

    I must say having looked at the "gadget" I wonder how noisy it will be and how much it would vibrate around. Also so small a theft risk! After all no one is going to stop some one walking off with it if it is too noisy:Rofl1:
