Aldi currently have a 300watt inverter on sale. I have allways founf the specials they have on camping 4wd gear to be good qualty for low prices.

the worry I have about the inverter is it is "modified wave" and have heard on this forum that they should be pure wave.

Its super cheap so if it will do the job for theoccasional use I would give it I'm not loosing much if I have through it away later.

The question is, how many other things are you going to be throwing away because of its modified sinewave ? Some electronics don't take too kindly to (modified) square waves powering them :((

We are a strange breed. We spend thousands on a car. Just over a thousand on a laptop etc etc etc and quibble about trying to get the cheapest inverter to run the expensive laptop and medical aids.

Personally I would not buy anything electronic from Aldi.

I would go to a good electronics store such as Jaycar and buy a good one.

This does not necessarily mean that all modified sine wave which is the same as square wave will damage your equipment. I have been using a $45 inverter from China for 10 years in our caravan powering up our laptop, DVD recorder,printer etc and have never had a problem. Would suggest that you use a surge arrester.

If the electronic equipment is powered through the AC/DC adapter as expected (I can’t think of any portable electronic device that would use AC power directly, especially under 300W) then there is no chance that it will be damaged by any inverter, even a “cheapie” from Aldi. Those low powered inverters are designed specifically to be used with notebooks/laptops etc.

Pure sine wave is best and most expensive, modified sine is cheap in comparison, and it will run most thing well, square wave are great also, but wont run tranny it comes down to what you want to run....lights...square, a tv...mod sine, a computer, pure sine...mod sine will also work but you are taking a gamble.

We have been using el'cheapo modified sine wave inverters for getting onto 10 years for everything and never had a problem. By everything, I mean charging batteries, running a razor, flouro lights, TV's and Laptops, etc.

Bought one of those Aldi 300w inverters last year when they had them last time.

OK for our use of powering the modem through it's power pack, and recharging other things that I couldn't get a 12v charger for.

Haven't trying running much straight 140v stuff, because we don't take any 240v stuff with us.

So it comes down to what will you be running off it?

Also note that the 300w inverter is only rated to 150w output (0.5amp 240v) when connected to a cigarette lighter (10amp12v), otherwise you need to use the clips to directly connect it to the battery, or install a 20amp 12v outlet, or wire it directly to the battery.
