Powering Laptops on 24 Volts

Hey all I bought a Laptop to keep me from being bored whils unloading & use my Autoroute with Gps to save carrying a FAT bag of maps around. Upon searching for a cable to power it from 24 volts Im finding that there are’nt many choices. So far Ive found One expensive cable @ £50 or an Inverter for 24 volts great for the truck but no good in the car…

Me lappy is a Acer Aspire 19v @ 4.74a’s & the close’st I can find is a dedeicated cable rated 90wats…

What do you use to power you lappys…■■?

I use a 12 volt inverter, it’s one I’ve had for years and I’ve used it with no problems in several different trucks.

Coffee do you use it has a sat nav your laptop? or do you have a sat nav has seperate?

No, mainly just use it for watching downloaded TV shows, writing or video editing.

I have a separate SatNav unit, although I don’t use it these days as I go to the same places 90% of the time.

I use a 120W psu (power supply unit) which I bought from Maplin. It was approx £20
It has many outputs from 12 vdc input.
I also use a 10Amp 24 vdc to 12vdc stepdown transformer which i bought at Lymm truckstop, they put a female socket on the output for you if you want.
I also carry around a cheap multimeter with me to test the output from the truck’s power socket to be on the safe side.
Some units have reversed polarity dc outputs which isn’t so much of a problem with the psu but blows a Tomtom adapter very easily.

on the Cable you put in the Cigaret Lighter Socket may be written 12V/24V,as i have it on all my Incar Charger,if Mobil Phone or Satnav

I use a 12v to 24v input, / 19v up to4.74amp 90w output charger I got from www.laptop-chargers.co.uk for £44-99. It works fine in my truck and my car.
Hope this helps

I use a 24v 300w inverter (it changes 24v DC, what your wagons batteries supply to 240v AC, what mains supplies. 300w is how much power is available at 240v).

The power supply unit for my laptop says it only needs 100w but the 150w inverter I got blew up when I was driving and running the laptop. I replaced it with this 300w inverter 3 years ago and so far, touch wood, had no problems. I’ve got a mapping programme on my laptop and with a GPS receiver, use it for Sat-Nav.

You can easily get a DIN (Hella) converter. Any truck accessory place does them. It’s just a DIN plug, a cig lighter socket.and a piece of twin core wire connecting them together. It’ll cost less than £5.
