    Not knowing a lot about electrics would a hairdryer run of an 1800 inverter?

    Yes no problem. Wifey users hers on the middle heat setting and probably uses about 1300 at that, any hotter it burns her hair

    If said hairdrier is less than 1800 watt .. short answer is yes

    However, every 1,000 watts will be drawing 84 amps from your battery...

    so, lets say it's a 1500 watt drier.. it will be drawing 125amps.. if it's used for lets say 10 mins.. that = 20 ah ..

    If your battery is 85ah .. you have a useful capacity of about 45ah , so now it is half empty .. or if you prefer .. half full..

    so , what rating is your hair drier (in watts) and what size battery(s) do you have (in AH) ?

    Not OT hopefully, more a supplementary question:

    So apart from high wattage items like hair dryers, leccy kettles and fan heaters, why have an inverter?

    Would it not be better to get a 12v adaptor / plug with the correct rating for the appliance (e.g. laptop)?

    In my case, to charge the following:
    • laptop (Apple magsafe connector from the 85W power pack is not a common item on 12v after-market chargers)
    • my Philips shaver (again a non-standard connector)
    • mobile phones (well why not since the inverter is there?)
    • occasionally, to plug in a Wahl hair trimmer if we are away for a few weeks at a time

    I have a 150W pure sine wave inverter that I fitted, originally, to run the MacBook Pro and a powered speaker system for watching DVDs. That was before we had a dome and TV fitted.
    Now, instead of hunting around for 12V charging adapters with the correct connectors, I can plug in any small 230V item I want to - I don't worry about the inefficiency of the inverter. For the amount it is used, I don't care.

    There is no better reason to fit an inverter than to run a hairdryer. My motorhoming life became complete when I could dry my hair and style it in the van. :Blush:

    That will be the impressive hairdo on the left in your avatar picture I presume!
    Respect - that must take some inverter power :Rofl1::Rofl1::Rofl1:

    Only jealous 'cos I haven't got any!

    Our hairdryer is1200W on full power. It is a travel type. Power used is fairly quickly replaced by solar in the summer. You don't need a pure sine wave inverter for hairdryer,kettle,toaster,washing machine etc,though they are much cheaper now than they used to be.

    Invertor

    We got a small 300w invertor (Aldi) because it would charge both the laptops..............it's hard to get a charger with the correct Dell adaptor.

    Also it covers us for any other mains item we may get in the future...........probably a razor or hair trimmer.

    My question is does a 300w invertor always use 300 w or is it the wattage of the item plugged in.........................so a 90w laptop only uses 90w.
    Thanks

    The wattage the item actually uses plus a bit. Your 90W laptop is probably drawing about 60W once the battery is charged, so your inverter will probably draw about 75W.

    We've an 1800 watt inverter connected to our engine battery, I use it for about 5 minutes to power my 800 watt baby bliss hairstyler, with the engine running unless we are parked up next to someone.

    I also charge my electric bike battery on it when travelling.

    Best bit of kit in our motorhome, cos a bad hair day will ruin any trip:Wink:

    It's the top that's denuded. Still growth around the sides and back of the neck!
