Wondering anyone here with a portable aircon has a power meter and able to say how much power it uses? Would be useful if you could also say how big your room is and how many kw the aircon is. Wanting to impulse one but scared of the electricity bill.
Cheers
Was kind of after results in the real world situations.
It's hard to know how much it'll cost to run an aircon system. You can work out the max hourly peak cost by multiplying the wattage of the unit by your electricity rate, but your airconditioning won't be working at it's peak the whole time.
There's a whole range of variables that need to be accounted for such as the temperature outside vs the temperature you've set your unit at - the bigger the difference, the harder the machine has to work and the more energy it uses. There's also the thermostat that turns the unit on and off once it reaches (of IF it reaches) the ideal temperature. The efficiency of your machine also plays a big part.
As an indication, I live in an apartment (60sqm) with a ducted aircon unit (3.5kWH) and it costs me about $0.30c/hour to run the aircon system while it's set to 21 degrees (outside being a bit over 30 degrees). When I turn the temperature down to 16 degrees, it costs me almost double at around $0.60c/hour.
I have a Kogan 10,000BTU unit to cool a small space. It's loud, reasonably effective at cooling a 4m x 4m room, and consumes 830w (measured) of power. So 1kWh every 1 hour and 12 minutes.
Hey mate, I am just looking at one of these now. How much does it cool the room down?
Is this the one you have?

There was a fairly good discussion about this here. Basically portable aircons are not particularly efficient, due to negative air pressure. Unless you happen to have a split cycle portable aircon (which is rare).
I heard you can buy certain portable aircon units which you can convert into "dual hose" setup so the condenser is cooled by the hot air from the outside rather than using your cool air from the room. This avoids negative air pressure and makes cooling more efficient.
Honestly, don't understand why single hose portable aircon units are sold at all. They are so inefficient.
I bought a portable air conditioner two Summers ago and bought it for $1,400. $50 for Delivery.
It cools the room down to 18 degrees. My bill last Summer was only $100 more than usual for the quarter and I had it on most hot days and nights.
Am using it now for this Summer and only expect to pay an extra $100 to $150 this quarter. It is worth it to me as I sometimes have it on all day and overnight.
You need to be comfortable in this heat!
The only downside is, it is quite loud and well, ugly - having the big hose go out the window. If I had known, I would have paid for one installed into the wall for twice as much. It is also very heavy at 50kg so I wouldn't take it upstairs… Therefore, not so portable!
doesn't the box/website have consumption and/or power input rating?
