how do I charge a 19.5 v laptop from 12V supply in motorhome?

[reiverlad]

As has been said - the 19.5v & 2A output are the main points you are looking for in a car charger that is also specific with the Sony tip to fit into your laptop.

Since Sony don't make car chargers they are hardly likely to approve their use - and certainly not from a 3rd party supplier !!

I have had a look for you and have found what you are looking for

I hope this helps

Typo sorry!

There's your answer. You need an adapter that gives 19.5v at 2A

Does the charger really say 19v or was that your typo? Most Sonys run at 19.5v. At least all the ones I've owned have done.

If you want to know the wattage, multiply the volts by the amp: 38 watts is what you need, so a cheap 60 watt one will be ample.

[Later] Forgot to add: don't ask Sony. I have never come across a more unhelpful, dishonest company when it comes to technical support. In my experience, their only interest is to screw money out of you. Guess why I no longer buy Sony kit!

You are right it says 19.5V!

Great, Thank you all!

I was not saying work it out yourself. I said that you have the information and we don't. Read what I wrote again.

You were the one who said "not sure what I look for" so I told you exactly what to look for and where.

Oui, un problème bien posé est à moitié résolu.

Thanks to all of you with your suggestions to my post "how do I charge a 19.5 v laptop from 12V supply in motorhome?"

I have looked into some of these possiblitys and it seems from reading the posts that
1. It seems invertors plugged into the cigarette socket can be a danger and therefore probably not suitable?

I always plgged my inverter into a cig socket that was in the TV compartment of the MH and never had any overheating or any other problems with it. That has been my experience.

Here's a possibility ...

For Sony Vaio Laptop Car Charger DC Adapter 12v 65w laptop Adapter charger | eBay

I use such devices on laptops and leave them plugged in whilst driving, sometimes for hours at a time, and have never had a problem.

That's not to say the occasional duff one won't slip through but that's true of all gadgets.

Maplins

Maplins usually have technical staff always available and stock numerous 12v cigarette lighter options. If not, find a different branch. One of them should do, but may take a little longer to charge, so you just charge while driving with your leisure being replenished. Beware of not to overload on the amperage or voltage, (get the tech advice), as it is fairly easy to blow the power pack fuse on the laptop.......good luck....steve Bristol

There was a time, many years ago, when one could reasonably expect a specialist shop to employ specialist staff. Sadly, that's not usually the case any more. You might be lucky and find a Maplin employee who is knowledgeable, but unlikely according to my recent experiences.

Sadly true. I've always found those in my local branch helpful and willing, but as Steve say, lacking technical know-how.

I found this site very useful in sourcing the same thing for my Lenovo laptop:

The Web's Largest Supplier Of Laptop Power Adapters & Laptop Chargers | Power4Laptops

What i would like to ask though is:

I have a multitude of small devices taking as many voltages, like 9 volts 500ma.

What i would like is a small 12 volt to various voltages (around 9 volts, ish)

Someone mentioned earlier in the thread about a Maplin one but i cant see one on their website and an ebay/google search is not really throwing anything up. maybe to how i am describing it

Anyone able to cast some light?

Many thanks
