From the site:
Another excellent product from one of the most advanced brands in inverter technology, this Intelli-Wave Pure Sine Wave Inverter from Projecta. This ‘Pure Sine Wave’ style of inverter produces the same sort of clean, consistent power that the power grid typically supplies, making it an ideal choice for anyone running sensitive electronic devices. This particular unit can supply 300W of continuous power, peaking at up to 600W. The unit also has a number of features to protect the unit and the battery it is being operated from, including low battery protection, as well as overload and over temp protection. The unit also features an automatically controlled fan at the rear of the unit to help cool the unit under intense conditions, whilst the specially designed housing operates as a heat-sink for the rest of the time, ensuring cool operation. This particular package also includes wiring to connect directly to a battery for permanent installation in a vehicle or caravan, and a neat on/off switch on the front of the unit, gives any user stress free control over its operation.

  What are people buying this for? Genuine question.

  I was in the market for one for my laptop when someone convinced me to just get a 12V adaptor to avoid the DC-AC-DC conversion waste. Though perhaps the power isn't as clean with my adapter, but then the laptop isn't worth much more than a sine wave inverter anyway.

  Is this more for car fridges and the like? 4WD stuff?

    Lots of laptops don't have 12V adapters and need 17-22V i.e. need mains charger. I'll also use mine to power my battery charger to juice up my Eneloops :)

    This deal is a great price!

      Certainly is cheaper than any of the Pure Sine's I found when I was looking. I'll upvote for that.

      Um… well, for those laptops, you could use this 150w Step up regulator which I've been using for about a year now for my laptop (which needs 19v) and another for my tablet (which needs 15v), both running off a 12v solar setup. Set me back a whole $12-14 for both modules!! :D You just need a screw driver and multimeter to set the voltage, and then maybe some superglue/locktight/putty to prevent it from moving if you can be bothered. And for charging batteries, I use a 12v charger (Opus BT - C3100). Nonetheless, I do like Projecta gear, and this is a reasonable price for a name brand pure sine wave inverter. I wouldn't be be running out and buying it though, as my $100 600w pure sine wave inverter is doing just fine… abeit gathering some dust due to disuse.

        @hoxygt: No problem hoxygt. those modules plus some cheap replacement power cords (just the bit from the power supply to the laptop for about $2-3 IIRC - don't know how I found it though) was all I needed, and I had a perfect DC-DC setup, which doesn't have the ripple which is what can kill electrical equipment with the cheapie inverters (the non- 'pure sine wave' types). Plus you don't have the overhead of the inverter, nor the inefficiency of the DC -> AC -> DC conversion. You just want to have some sort of solar controller or low voltage protection between the regulator and the battery, to prevent causing any damange to the battery! If you're willing to do some DIY… it is pretty easy nowadays to put together some neat stuff… there plenty of modules you can bolt together and make whatever you want or need, although it doesn't look as pretty as a ready-made unit.

        @pfeerick:

        Nice - I think my battery charger actually takes 240VAC and converts it to 12V or something anyway so with the right cord I might be able to use your method and save all those conversion inefficiencies….

    I guess the best thing is that you don't need to think about buying 12v adapters for things you might want to use. Just plug anything you want (<300w) into this and go
