  Is this need a hose and let the hot air out via windows?

  •

    Yep. Which means it sucks outside air in at the same rate - one of the main reasons they're so inefficient or ineffective.

      Another problem (I bought one of the Kogan units) is that the reverse-cycle function doesn't (and cannot) work. When you try to heat your room, you get luke-warm air at best, not even close to the claimed 2.6kW.

      The way a split-system reverse-cycle aircon works is it extracts heat from the air outside, then exchanges that heat with the air inside. That way it can get 3-5kW heating from only 2kW power usage.

      The Kogan unit (and most portables) cannot do this - they have only one hose leading outside, and that only blows air out. There is no hose intake for it to get air from outside. That means it can only get air from inside the room, suck the heat from it, and give it right back to you. Net gain: almost nothing (no more than a little heat from friction).

      Since it can't get heat from outside, and it doesn't (and can't) draw 2.6kW from the wall plug, it can't possibly add 2.6kW of heat to your room - there's nowhere else it can draw the energy from.

        …and despite it all, I wouldn't want to have been without my Kelvinator when I was renting a west-facing sweatbox apartment. Mine at least undid a bit less cooling than it delivered.

  Simply connect the exhaust to a door or window

  Just for a rough idea, postage is about ~$68 to Perth, ~$33 to Sydney and ~$22 to Melbourne.

  I was looking for one of these units and was tempted to buy until i saw ABC reviewed it and said whilst it worked well it was insanely power hungry:

  Fan only mode : 73W | $12 per month | $140 per year
  Air conditioner mode: 1025W | $162 per month | $1970 per year

  No thanks! i think id be better off saving up and getting a more efficient model itll probably be cheaper in the long run

      So what!!! - you dont like portable air conditioners fair enough, but why neg the deal, when for some this type of airconditioner is the only one they can use in many rental situations. Maybe you can afford to live in a bought house but others cant.

      Make the comment BUT to neg vote the deal which can hide it from people's consideration and also the comments that might be useful is a little selfish

        There are people who survive just fine without a mobile phone. You can too. … or can you?

        You're meant to vote on the deal, not what the item does. Can you find a similar device for less than $199?

    While I can't comment on the efficiency of this unit, those dollar amounts are stupid and assume 24/7 operation.

    Makes as much sense as saying a Toyota Prius is a fuel guzzler because if you drive it 24/7 you have to fill it up everyday.

      Dunno about you but some places in this country are 30-45c for weeks on end, and barely go under 25c over night :)

      I find these "window duct" ones terrible as they suck air into the room disregarding air pressure so you end up getting hot outside air sucked in through the cracks and gaps in your house.

      Don't go cheap on A/Cs :)

        Cold shower before bed and a fan was how I survived a couple of summers in a room that couldn't even get decent airflow through the windows on hot summer nights.

        'Twas a joy regularly waking up in the middle of the night because of heat-induced muscle cramps

      "This large machine is hardly a model of efficiency, but it's the only type of product with the grunt to cool an entire room on a very hot day…This model comes from Kogan but it isn't the latest model (which can also act as a heater). Nonetheless, it has similar(ish) power usage and is generally similar to other portable air conditioners…Portable units like this will likely get more efficient as the price rises, but bargain units like the Kogan cost just $300."

      Obviously it is about an earlier (Cooling only) model

        Thanks, also its based on the cost being $300 vs the $200 in the deal (not sure if ABC allowed for postage)

        But the heating needs to be checked by those who want to buy, if its just a heater element (making it a standard 2400W heater with the associated costs), or it's true reverse cycle

    On my calculations, using 30 c per Kw for electricity, it would need to be running 6500 hours per year or 18 hours EVERY day of the year, at its highest power consumption, to reach $1970. I don't think so… shame on you ABC.

      They're not hiding the fact that they're talking about 24/7. It's in the opening paragraph:

      Thanks to soaring electricity costs and the potentially-enormous power drain of cooling equipment, few people can happily leave aircon running 24/7. This is especially true for those renters who must rely upon portable devices.

      and also when talking about the first monthly/yearly price:

      Still, if it's left on 24/7 for a month

      That said, no-one sane leaves an air-con on 24/7, 365 days.

      I'd imagine for a normal person who only uses the heat or cold options for a grand total of something equivalent to 60 full 24/7 days per year would be a more relevant figure. So ~$330/year.

    bamzero on 26/02/2013 - 13:37

    By my quick calcs on what we pay per unit (about 25c), those $ amounts above are based on running the unit something like 20 hours a day, 365 days a year which ovbiously no one is going to do..

    To see how much it would actually cost based on your usage, (1025W x Num of hours)/1000 will give you the KWh. Then just multiply that figure by your unit price..

    As far as these types of aircons go, 1KW is not so bad. That said for a 3.5KW cooling unit I'm guessing power draw is probably more like 1.5KW.

    Otherwise can go for the evaporative type, but obviously not the same thing.

  Yeah, horses for courses. Don't buy this in if you live in tropical Queensland. Portable units are good for Sydney weather where you don't need an aircon except for a few killer days a year. Useful for short-term renters etc.

  Don't think you can neg this deal on the basis that installed aircon is better - its still a good deal for portable.

  I actually bought this exact model when Kogan had their free delivery deals some time ago. They noted that it would be delivered after 30 January but it actually arrived 26 or 27 January I think. It didnt get a lot of use since it started raining and flooding around that time :(
  As for its cooling ability, it seems to work reasonably well at maximum setting in a room that is about 4mx4m. Takes a little while to cool the room down (20 minutes +). I measured the sound levels and it is about 62dB from about 2.5m distance at maximum settings. I didnt notice a great deal of difference in sound levels from maximum settings and sleep mode (quite mode) ~2dB.
  Hope this helps.

  Unless, you blow this at ur body…. its not very effective in cooling ur room
  if u want a good portable one buy a good one.. i bought a $300-400 and realised after many reviews that if u want a good portable, u might as well get a window one and install it.. or pay a good $700 for a decent one..

    So true. Even the 4.3kw models will only cool a very small room, but they are fairly good at getting the humidity down.
