Hi everyone, I am looking for something to charge the lap top whilst we are driving. I had one of these can style inverters in mind.

Will this do the job. I am favouring this one because it has the usb port which means the ipod can be charged as well.

Jaycar stuff is good but the Kerio adaptors at Dick Smith are great and have a long standing rep for the job. Not cheap at $90 but they will run and charge your computer where as a lot of others will only charge.

What Mick is saying is buy a CONVERTER that ups the car voltage to what the laptop uses usually about 19 volts.

An inverter is Ok except if someone spills a drink on it it may well light up your life somwhat if you get what I mean.

Much safer to stay on low voltage as it will do exactly what you want

Projecta also make them and are available at some Battery World shops.
Make sure you buy a 6 amp model as the 3amp ones arent quite powerful enough for most laptops and heat up when you start doing things on them.

have tried both and prefer the low voltage method

Some of the newer laptops need more than 6 amps.
I have a Targus 6 amp jobbie that worked fine on my previous 2 laptops, but won't run my new Toshiba (6.32 amp) and charge the battery at the same time.
Anybody know of a converter rated higher than 6 amp?.
I have searched, but had no joy :-(

Hi Glen

You might just be lucky enough to get away with running your laptop with a lower voltage i.e. in converter is set to 19 try 17/18 volts , also often helps to reduce screen brightness for less power use.

Hi Cram,

I have set up a 600 Watt inverter (bought off Ebay) connected to my second battery. I then connect a power board to the inverter and run my Laptop and 8 inch TFT screen and can charge my mobile all at the same time. This set up works well for me.

Hi Cram,

Had a similar thought with an inverter setup to run the Dell laptop on our road trip. While many have had success with any type of inverter, modified or pure sine wave types, we searched through e-bay to find a 12v power supply to suit our particlar computer. Had no trouble with the power supply, even with some heavy use during the trip, downloading photographs off the camera or checking e-mails and a little web surfing as the connection permitted. Better safe than sorry, though others could differ in their opinion and the end cost was not too great as insurance for the computer.

Hope this helps.

PS It may be even cheaper if you can source you i-pod charger from the same supplier.

I have an IGO Adapter

IGO PS00099

Plugs into your cigarette lighter socket and straight into the laptop.

Never had an issue with it. It can also charge many other things including Ipod's if you purchase the correct tip.

G'day Cram, I run a 500 watt "Pure" sine wave inverter. I've travelled thousands of K's in remote and rough places, I use it to charge laptops (one of which runs continuously for my GPS tracking system) digital camera, sat phone, torch batteries etc. Hard wire it to your auxilliary battery and keep output leads (240 volt) short and safe and you won't have a problem.
PS Make sure it is a "Pure sine" inverter, as modified sine can heat up modern electronic chargers.
Safe travelling.
