Gidday again,

Further to my PostId 8853 about a 12volt DVD player for the car, I have another question. Has anyone run a Laptop in the car thru an inverter, can it be done as I've heard that inverters can damage anything with a laser disc.
Any info would be appreciated.

yeah I have a laptop that's done many hours thru an invertor without any damage.
It's a high quality sinewave invertor though.I may be mad but I'm not crazy

This is what I have been told , If you have laptops or similar electrical goods that have a transformer to reduce volt's , then you dont have a problem with Square wave inverters , its only when you dont have a transformer that it can harm elec. goods , like TV'sVenus Bay

We had a Blackout here in Mackay last night..5 minutes before the Bill was to start. So I grabbed the 300watt Dick Smith special hooked it up to the battey on the troopy and we were the only people in the street watching TV. We have used this no frills inverter while camping and the TV is still ok.

I used a 300W Dick Smith Inverter to run my Laptop for a while and it was moderately successful. I noticed that the laptops transformer would buzz where it was quite when on the mains. After running for a while it would get hotter than it did on the mains and also the inverter would give an overload signal and then turn off. You could turn it off and then on again and it would work for a while but then would keep switching off and want to be left off for a while. Kids not happy watching their DVD's and the lights would go out about 3/4's of the way through the movie....."Ohhh Daaaaddd". Now I have a Jaycar Pure sine wave inverter and it works beautifully - Laptop transformer is cooler and quieter. Kids happy too. Hip pocket empty as well but ......

Hi Mick,

I run an IBM T30 Notebook off my DSE 300 Watt inverter ($99 version) and have had no problems, sometimes up to 6 hours !

What is the power load going to be like through an inverter?? I have a 12V power supply (cigarette lighter), which came with an adapter for just about every type of laptop power connecter there is.. My Toshiba runs at something like 16V.

Is the way I have it less load than 12V to 240V and back down again - a mate of mine finds he has to run his car if trying to drive the laptop for any length of time, whereas I can run mine for a fair while..

I have a 150watt Pure Sinewave inverter from Jaycar and it runs a Pioneer Norebook laptop with ease. No noise, no distortions, no troubles. The inverter cost $300 however. I opted for a quality item.

Before I knew that there were "inverters" and inverters I ran my laptop quite successfully on my 150W Supercheap "inverter". No problems.
Now I'm not so sure thanks to all the talk on this subject.

As someone else said the inverter to lap top transformer is ok (most times) as long as the inverter is more than 100watt.
My lap top _Affordable_Storage_Drawers.aspx just on 3 amps from the inverter ( 36watt ) the inverter being 150watt Tricky dicky special. (Modified sine wave inverter). so far so good.

My 100 watt inverter won't run my older Tosh laptop. I'd suggest 150 watts would be a minimum for most laptops.
