  • Can this power my fridge and washing machine ?

    • At the same time? No way but depends of the size and watts of each unit

      • but definitely can do 1 at a time?

        • I can't say do you know the specs of the fridge and washing machine?

        • +3

          If the washing machine is using the built in water heater it may draw too much power.
          Even a kettle may be too much for this generator.
          However you cannot expect much better for this very low price.

    • +1

      If you mean a normal washing machine, it's unlikely as the heating element probably draws 2000w.

      The fridge may be ok, but again if it's frost free it will have a heating element though power draw won't be as high as the washing machine.

      • There are top loaders that don't heat their own water, get it from the tap.

    • +1

      Won't do a normal washing machine as they have heating elements that you can't always turn off.
      Might do a fridge if the startup current isn't too high.

      As mentioned in the blurb, "power laptops, DVD's, TV's & other digital appliances"

      Large whitegoods are probably outside of spec.

      • There are washing machines that don't support a cold wash?

        • Yep plenty of front loaders only go down to 30c or so.

          • @tanksinatra: Never heard of a washing machine that wont do a cold wash…

            • @Cheeper: Should be able to turn off hot setting.
              But then, I've never used one that heated its own water! Top loaders usually have 2 inlets for hot & cold water.

            • +1

              @Cheeper:

              Never heard of a washing machine that wont do a cold wash…

              Then prepare to hear about new things I guess?
              Many front loaders will still heat on the cold setting if the inlet water is too cold (e.g. below 30c or 20c). I'm not exactly sure why, I think it's to make the powder dissolve out of the dispenser. I've used LG's, Miele's and Electrolux's which would always heat a little bit regardless of the hot/cold setting.

            • @Cheeper: This seems really stupid, I guess its a 1 star washing machine or something?

              My front loader is from Aldi and it allows a cold wash (basically no temperature wash)

      Did you read the Deal Description of suitable uses?
      Suitable to power laptops, DVD's, TV's & other digital appliances

      Do you think a high drain appliance like a washing machine or fridge fits that digital appliances description? Typically, with motors, there is high consumption when starting.

      Don't think warranty would cover failure due to such high load on such a tiny gen.

      • why so mad ?

        • +1

          Mad? When people fail to read what is in front of them, & ask others to read it for them…

      • Trying to push power supplies past their rated capacity was a common issue I used to deal with in off-grid power systems. I'd see burnt out units.

        I recommended for longer life of unit & reliability - operate at half rated capacity.

        That's a measly 400W here. It is a (Super) cheapie.

        Motors can draw a lot starting up & depends on type of motor & loads. (eg washing a load of heavy jeans vs undies)
        Check if gen (or inverter) can handle any peak surge current & how long for. As this is for low consumption devices, there is likely to be little excess capacity.

    • Blackridge 800w continuous

      Probably one item. what's the wattage on your fridge?

      Stanley 2kva (2000w)

      Can likely handle fridge AND washing machine. but add the watts together and see.

      Toasters, heaters, kettles, irons, ovens all chew power. A washing machine hearting water will too. a warm fridge being powered on to cool down will too (but not as much).

      why are you asking? for a blackout?

      • Wattages shown on appliances don't show the short lived surges associated with motors turning on & off. Size of surge depends on type of motor & load. So this must be taken into account when sizing small power units.

        (Resistive loads like heating don't have similar power spikes, so can use the manufactures figures.)

        These surges don't matter when on mains power - they even out over the system. So manufacturers don't show those details. But on limited capacity supplies like this, surges may cause damage to the supply.

        More powerful supplies often allow for short limited intensity power surges. It should be stated in the specs. (I had more experience in inverter selection than with gen.)

        Best to go by power supply manufacturer's recommended uses. In this case - low power consuming digital equipment (mains powered laptops, DVD's, TV's).

        When tempura asked Can this power my fridge and washing machine, my guess is they knew the answer. 800W max is very little power.

        In off-grid limited power supplies I would ask - why do you need both plugged in at the same time? Generally, you can turn the fridge off for the time it takes to wash 1 load.

        It sometimes just takes a different mindset💭

  • Would you leave petrol in the tank till you have an emergency or do you have to fill up the tank before you use it?

    • I believe petrol goes bad after a while.
      Not sure what best strategy would be.

      • Jerry can?

        • +1

          Petrol may go bad in a jerrycan as well.
          However if you have a mower and use the gas regularly…

    • I personally leave mine almost full with 95-98 octane and run it ever few weeks or so to clean out the carb. If its purely for emergency use maybe fill it up before use. Just a tip a 5L or 10L jerry can like is a must for refuelling https://www.bunnings.com.au/icon-plastics-fuel-can-and-poure….

      • You obviously did not read the user manual and have voided your warranty by using 95-98 octane fuel. Says to use only unleaded 91 octane fuel. See page 9.

        https://www.supercheapauto.com.au/on/demandware.static/-/Lib…

        FUEL - ONLY USE UNLEADED PETROL (ULP)
        Fuel tank capacity – 2.1 litres (2.1 L)
        Use of incorrect fuel and/or oil may damage the generator and will not be covered under warranty.
        Do not use E10 or any type of ethanol fuel as this will damage the generator and will not be covered
        under warranty.
        Do not use high octane fuels (greater than 91%) as this will damage the generator and will not be
        covered under warranty.
        • Ensure you use clean fresh unleaded petrol (ULP).
        • Use a clean approved container to store your unleaded petrol (ULP) in before decanting
        into the fuel tank.
        • If contaminated (dirty) or old (stale) fuel is used any damage caused will not be covered
        under warranty

        • billy_bob I have a different brand generator, it runs on 95 octane

          • @DannyBoy: All good, yours must be the performance model :) Just thought it was worth a mention, as the OP did not state fuel type. I thought these things always ran on diesel….

            • @billy_bob: No problem billy_bob. I didnt neg you btw. Yeah I think the serious stuff runs on diesel.

              • +1

                @DannyBoy: Thanks mate, there are some bloody morons on this forum who neg for no reason. I try to help others out with an informative comment and get negged. WTF!

    • +1

      Probably leave it in a jerry can with some fuel stabiliser so it lasts longer

      • surely the same jerry can for your lawn mower and whipp snipp can be used .. so it always get replenished.

        • NO thats 2 stroke mixed with oil DO NOT add that into this kind of generator or any other 4 stroke type

          • @DannyBoy: am confused .. a petrol is a petrol; a fuel is a fuel.

            • @tempura: for 2 stroke engines you need to mix oil in the petrol
              most trimmers and some lawn mowers are 2 stroke and need this
              4 stroke motors have a separate tank for oil and will not function properly with 2 stroke mix.
              Hence the difference.

              Note that 2 stroke mix will go bad much faster than the petrol as is.

              Darn, I am trying to reply to @DannyBoy
              How can I delete the other post?

              • @cristtos: LOL .. just click on the report and pick 'Duplicate' then admin will sort it out.

          • @DannyBoy: lots of people have 4-stroke garden equipment.

            • @Radar: Not worth the risk in tempura's case

    • while you're at SCA buy some stabiliser, helps to stop the fuel varnishing in the carby as well i think.

      https://www.supercheapauto.com.au/p/sta-bil-fuel-stabiliser-…

      • Note that is only for tanks.
        If you keep the fuel in a sealed jerry can, you don't need stabiliser.

    • Thanks for all the comments, looks like fill up before use it is then.

      • A small tank like this I guess if its not used frequently. As for cars with bigger tanks its always better to leave them with a full tank as the petrol takes longer to go off, unless you plan on not using it for 6 months then an additive might be the go as mentioned above.

    I have the stanley 2kva one,bought from Costco for $479.Im very happy with the noise level,it's like standing next to a scooter.

    • Different class altogether…

        Stanley 2kva is listed in OP

    • curious - petrol or diesel?

    will this be able to power the NBN ntu, modem and a laptop?
    Very essential internets!

    • +2

      it should :)

  • Does this come with warranty??

  • +1

    For $150 it seems like it'd be hard to go wrong. Seriously tempted, and I already have the Stanley one from a previous Costco purchase.

    Edit: oh, no local stock. $25 delivery

  • +2

    Thanks for the heads up.

    Went instore today to get one and noticed they had the 1700w model for half price at $249. Grabbed that instead.

    I have had the 800w model for near on 8 years now and it hasn't missed a beat.

      Which one was it buddy?

      • +1

        Got mine in WA - Spearwood. Midland had some as well.

  • Just note that there is no 12/24v output … which is a deal breaker for me … going to see if I can get the 1700w model

  • +1

    🚨$44 650W 2stroke Blackridge Generator🚨
    No inverter, so no controlled Output!
    - Not for use with electronics (not sine wave)
    - Requires 200W min consumption to maintain correct power output
    18kg
    Up to 4 hrs operation on 1 fill of tank
    Could be handy to operate some power tools on building sites.

    Reports as in stock at enough stores I searched to be available to some.

    • That's a bargain if one should require a generator like that
