They are quite suitable for that Friar - but it doesn't hurt to take your laptop along and try it in the shop.

Personally , if your laptop requires more than 14vdc (most do these days) and hence you cannot hard wire it direct to 12v supply as I do , then the better option is to buy the dedicated
laptop supply which is about $40 and deliver 6amps at any voltage that your laptop requires.

A 6 amp one will be more like $69 at a Battery world and dont get sucked into buying a 3amp one as they arent good enough and heat up badly.

Should have said they are called CONVERTERS and up the 12 volt to various voltages as most lappys run on 18-19volts

Hi Friar

My Toshiba laptop only requires 14.4v so I run it direct - however if you are not into this stuff then I don't reccomend that path.

Many places supply what you need , for example Jaycar model MP 3467 at $47 retail but often $39

Ask again if you have trouble locating one

My fairly new Dell laptop runs fine from one of the cheap Dick Smith inverters. Might be 300W though, can't recall (didn't cost much more than $50)

If you reckon you need a 150w- then go for a 300w..
I found with my puter it will run all day on 150w- but does 'overload' it a bit on Start Up- so I did exchange the 150 for a 300w at Jaycar with no problems..

I think the 300 watt inverter I bought from Dick Smiths was only $80,which is only $30 more than the 150 watt on special

Try before you buy. I had trouble with one of mine not wanting to boot on a 150 watt inverter, had to move up to the 300 watt.

Do the 300watt inverters come with a plug for a cigarette lighter.Friar.

Hi friar
It very much depends on the wiring to your ciggy socket
ON FUL LOAD the 300w inverter will draw ABOUT 25AMPS, few if any ciggy sockets are wired to carry that sort of current & the plug will not either.
OF course the inverter does not draw that if it only on light loads such as chargers, lap top charging etc,
Voltage drop due to wiring being too light can also be a problem. Best to connect direct to battery with heavy wiring with a switch to switch off when not in use.
Also just be aware that some gear do not like MSW inverters & no way to know IF they will work without trying.
Pure sine wave WILL work all gear within their watts capacity ,but are more expensive.

Wait till one of the kids spills a drink on the inverter in your car That will light up your life a bit.

Far safer to buy a converter and up the voltage from 12 to whatever you need for your lappy

Aldi have a brilliant little inverter on occasions for $49, 300w units. i have 3 of them in various vehicles/camper and they all have performed faultlessly. i have charged many items on them(laptop,handheld radios,dvd players etc) and had no issues.

my laptop draws too much power through my DSE 300w inverter when it is plugged into the gigg lighter unless the vehicle is running (it screams then turns off)

i really should wire up a better power supply
but i usually use the alligator clips and run the inverter off the battery when stationary

Hi
The problem is due to voltage drop in the small wiring to the ciggy socket see reply post6 to friar
