Hi, my Toshiba laptop need a 19volt DC input - or at leats that is what the 240 volt power supply feeds to it.

If we are wild camping and not on hook up is there any way to power the laptop - the battery only lasts about 1 hour.

Any solutions would be welcome.

Many thanks

You can get an inverter which will give you 230v AC power which can be used to power other things, depending on how powerful an inverter you buy.
You can go to maplins or the like as Viktor says and get a one size fits all computer power supply.
You can also get an in car adaptor from Toshiba.
What I tend to do is to charge the laptop from my inverter while on the move as this does not drain any of the batteries and I don't use it much while away
 
Check on Ebay, you can get 12-19v inverters, much more efficient that 12-240volt, inverter then a 240-19 converter.

Laptop Car 12V DC Charger Adapter for Toshiba Satellite A100-209 | eBay

I bought from them and the service was brilliant, let them know the model and they'll let you know the charger.

My Compaq uses one every week. Best if you charge before totally flat.

I wired an additional cigarette lighter from the leisure batt, some vehicles lighter outlet isn't operative with the ignition off
 
I use a 12v adaptor which steps up to 19v. It's more efficient than turning your 12v dc into 240v ac then back into 19v dc...
 
Are all these adaptors suited to any laptop or do you have to buy one specific to your own brand/type of lap top?

They come with multiple connectors so will fit just about anything. Just plug on the right connector for your laptop, set the voltage to what you need (i.e 19v) and Bob's your aunty on a cross dressing weekend.
 
I didn't realise such things existed, so huge thanks for raising the subject :)

I would imagine you'd need one for your specific laptop - mainly because of having the right connector on the laptop end. I just Googled "Dell 12v laptop charger" and instantly found an Amazon link for my Inspiron 1525.

If you take a look, it appears to be one continuous lead, so it wouldn't fit all models. Mind you, that doesn't mean that someone else might know something I don't... ;)

Edit: See ^^^ I said someone would know something I didn't and by the time I posted, there it was :D

Just get one of these. A lot cheaper and they'll charge pretty much anything with all the adaptors and voltage levels.

I believe they require a 24v input voltage and therefore not suitable for most vans. Regards Helmit
 
I bought a universal laptop charger from Maplins for £19.99 a couple of years ago. It came with various connections for different laptops.

If it is the same as mine, it does not do 19 volts. It steps up 18 - 20 - 22 etc.

I need a 19 volt one as my laptop has died and I have a new netbook which is 19 volt. Every single netbook that I looked at was 19 volts.
 
Mine is 19volt input, but the battery is only 11.5volt. So it will run on 12 - 15v straight from the vehicle battery, but the screen may not be as bright.
Look at your laptop battery & see. You are not going to damage it by feeding a lower voltage than specified. Just make sure you get the polarity the right way round.

The one I listed above on ebay is rated at 11-14v input so shouldn't be a problem.

I've been using one for months without issue.

In that case its a bargain, thank you for the link.
But running the laptop direct from the 12v vehicle battery is the most efficient of all, as nothing is lost in the converter, and is not going to damage a laptop rated at 19volts - providing its wired the right way round - polarity correct! The voltage (11.5 to 14.8 volt) and screen brightness will be somewhere in between when its being run on the laptop battery (11.5 volt) and the mains unit (19 volt). The only problem I can see is that it may not be enough to charge the laptop battery.
