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

Ive used the Maplin multi voltage charger for all our laptops for years now. Still going strong. I tend to try and keep the laptop fully charged as much as possible as if its fully discharged it really canes the battery charging it and running it at the same time. Or ill charge and use it mainly in the morning in summer when there is a surplus of solar power. For iPhones etc I just have a bank of 12v sockets and USB plug in chargers. Apple in one of their updates craftily disabled support for third party cables! I stopped updating mine, more hassle than its worth

The sine wave inverter recommendation is a good one. I found out the hard way charging stuff like tooth brushes on a cheap one and it knackered them. Its seems ok on Cameras batteries etc that have a 240c charger but Im not sure I would charge a laptop on a cheap inverter.

It's that mobile phone that is the weight of a brick ?
Or did I spell it wrong ? Should it be IPhone.
Or are you responding to the fact that in posts we sometimes use that saying as our van is so basic ?

Cheers.

Ok, so can anyone recommend something for a Samsung netbook? Not sure what to look for. I also have an iPad which I charge via 12v but don't have a dedicated cable. Should I? I've noticed sometimes it takes ages!

Do a search for "car charger" with the make and model of the device/s you want to charge.

I don't use Apple kit, but I understand they have their own ways of doing things. Best to find a dedicated device if I were you.

Just done that and they're all in the £25 range apart from one from America which had £11.01 postage!

Look for the label!

Your laptop's charger will have what voltage and wattage it puts out written on it. The laptop may well have the same information on it as well. You have the plug that fits into the power socket: only you can measure it.

There is no point asking other people: you are the only person with the relevant information.

Alternatively, you might be able to look online if you find EXACTLY which model and version of laptop you have.

Thanks Hairydog. Sorry for asking other people on an advice forum! Not... 😄

Hi ya Carol.
Hairy dog is right in what he said, but I suppose in posts it comes across a bit Blunt at times..(Or maybe he is a Grumpy old Bugger at times), his posts are often informative though.

Try looking on your laptop/Notebook for a Make & Model number & -

Note the INPUT


& the Charger -

Note the OUTPUT

It's these that are the important factors, & need Matching. Hope I haven't confused you more

Thanks to all but I am still confused

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?
2. The specific convertors sold on ebay and Amazon I had already looked into and nearly bought as they seem to be the best way to go but when I rang Sony they advised me against it :rulez:saying it was unwise but that may just be cautionary? it worried me that maybe these coverters could damage the laptop
3 Maybe I am just being too cautious??? but I don't want to damage the laptop vs I do not want to hook up to mains all the time we are away as that defeats the point of just going and stopping where we can.

I have looked at the details on the back of my Sony Vaio Ultrabook product name SVT1311C5E and model No SVT131A11M 19.5V 2A
On the charger itself it says Sony AC adaptor 19.5V input100-240V - 1A 50/60Hz Output 19.V -2A
No where can I find out anything about Wattage? perhaps I am being dim
 
19 doubles is about 40w +2ah,the cigy to 19.5 chargers are 100% ok at this very low power so no real heat to melt anything,go ahead buy one never mind what sony or however say there just covering the back.

I'm so sorry. I didn't realise you didn't want advice.

Now that's silly but basically you were saying work it out yourself. That's not really advice. The information you gave was obviously good but why didn't the OP get the same "advice"? Surely the point is benefitting from others' experience and not having to start from scratch with a problem? Thanks anyway. 😊

If you want information without aggravation then google it ..... much safer than asking on here. :lol-061:

That is why I don't have a WC sticker in my windscreen now, it might attract the wrong (grumpy and bombastic) type of motorhomer.
