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.

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
Cheers

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 :-(
Cheers
Glenn

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

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.
Greg.
