    Cordless Gtech vacuum



    CLICK HERE TO REMOVE THESE ADVERTS
    Hi, I am thinking of buying a Gtech cordless vacuum MK II. I am primary buying for the house but it would be very handy to take away with us in the MH. It says 22v with a 22v lithium battery. Obviously I would only want to charge it off the inverter when we are moving as it takes 4 hours to charge. Would this be alright? What I am worried about is if the battery is the same as a rechargeable toothbrush that the inverter (600 w) will eventually ruin as it is not purewave.

    Personally I wouldn’t risk it as modified sine wave inverters do not go well with many products as well as electric toothbrushes. I had a msf inverter on a boat and some laptops malfunctioned when using it for example.

    You've probably already made up your mind but Dyson do this ONE which can be charged direct from your car/van cig lighter socket.
    as well as mains

    We have both a G-Tech Air-Ram and a Multi. The Multi (hand-held) is excellent for the motorhome. FWIW, we did a 6-week tour through the Netherlands, Belgium and France during which we brushed through the van daily and used the multi on the carpets and upholstery once a week. We didn't need to recharge during the six weeks of the tour. It only takes about five minutes to do our van and you get up to forty minutes per charge. Also, recharging the battery every whipstitch can shorten battery life; much better to wait until the machine indicates the need to recharge. HTH, Geoff

    Rechargeable toothbrushes use induction charging which will self-destruct if used with a modified sine wave inverter.

    Devices that are charged using a plug-in 13 amp socket device should be fine with a modified sine wave inverter. The charger is a switch mode power supply which may be expected to suffer no ill effects.

    No, it will use a switch mode power adapter which will work with any waveform - even a 1hz square wave would be fine
    Toothbrushes are different because of the waterproof inductive link.

    Which is precisely what I said earlier!
