inverter

Hi Zedd

A good modified sine wave will do the job.

We have tested many and the Projecta and Sidewinder units are fine for laptop and camera chargers.

Here is a table of size required.

Go the pure sine wave, more effecient for a start. It also blows up fewer power supplies :))
For size you need to know the current you will draw from it. Laptops, phones, small light can be easily done with a 300w unit. Just don't expect it to run everything at once.
Also get a good quality unit, as some of the cheaper ones are rubbish.

I bought a 330w pure sine wave today from Jaycars. I only need 150 but for twenty dollars more well why not. The unit should have plenty to spare and the sine wave will not produce that feedback or whatever it is that blew up the old square wave.

Buggar me i got home and the unit was crook. No sweat they changed it straight away with apology. This model boasts all sorts of protection and its a new one for Jaycar and cheaper than previous, they said.

So lets get a good plug that wont slip out and I went to Cheap as chips to get it. The one on the inverter was crap. The wires looked nice and thick but it was all insulation and adequate copper I guess. The fifteen dollar plug made in 'Australia looked good but hell of a time making the cable fit. I had to strip back the bulky insulation and use electrical tape in the end.

I already ran heavy wire to the cig lighter so we should have a goer when I get the fridge.

Thanks for your feedback. My next question is this. Do these inverters run directly from the battery or do they run through the cigarette lighter? I have a dual battery system from which my engel fridge and lights run. My concern is that I don't want to damage the laptop. I have an IBM and know that I can buy a DC adapter for it, but I may change brands down the track so I was looking at an inverter so it will charge any brand of laptop. How long can you run an appliance from an inverter?
