I think there has been a discussion on this topic before but I can’t find it.
Just about to go and buy a laptop, and then I am going to need to buy a voltage converter 12 Volt to 240 volt,
Can anyone send me the link to this topic please, or failing that give me info where to get one.

You need an inverter. Quite expensive, but handy bit of kit. Try ebay or maplin websites. Make sure it’s 12v you need cos most trucks have a 24v cigarette lighter socket. Don’t want to fry the laptop 
Maplin also do a cigarette lighter power supply for laptops, but again it is 12v, so you need a 24-12v adabtor if running on 24v 
Whilst on this topic, I got given an inverter the other day, but when I plug it in, the power light on the plug stays on but the box beeps and the power light on the box goes out 2 seconds after plugging it in. Anybody got any ideas whether it is broken or am I doing something wrong? Have checked it is a 24v one and the connection plug is firmly inserted in the socket. What’s wrong??
Thanks for the reply Lostpup.
It is 12 volt I need I have the Kettle permantly plugged into the 24v so there is no danger of frying it.

Make sure the socket you plug it into has a big enough dropper, if u use the 12v lighter socket it may not run it through the inverter.
In my volvo, ive got a 24v socket in the back, and plug the inverter into that and it runs it fine, it will cost you about £40 for an inverter unless you want to go all the way and get a pure sine inverter, then it will be more up round the £200 mark, but to just run and charge the laptop go for the cheaper option.
Anyway, take a look on www.roadpro.co.uk then you will get some ideas of how much etc
Thanks Gurner
Just bought one off Ebay £29
