Aftermarket AC adapters.

Are there any maufacturers of aftermarket AC adapters that make ones with the same electrical specifications, but in a smaller size? The adapter for my laptop is a big bigger than i would have hoped and so i would like to change it for a smaller one if possible.

 

First, Samsung use an unusual DC plug / socket so your choice of third party PSUs is limited.

Second, The X65 is likely to need the better part of 90W if the CPU / GPU are working hard and the battery is being recharged. 80W might be the upper limit but that's not much below 90W. Samsung seem to have standardised on 60W and 90W for all their current models.

This site has a good selection of Samsung-compatible PSUs. Even if you get another 90W PSU then you may discover that it is bigger than the Samsung PSU (the 90W Liteon PSU for my Zepto is bigger). However, the advantage of having a 2nd PSU is that, if you are using the computer at two locations (eg home & office) you leave a PSU at each.

yeah, be VERY careful with aftermarket AC adapters

 

Do you have anymore info on the subject? was a bit vague

 

Well i bought a universal ac adapter for a friend of mine who's ac adapter died.
it had like 6 connector pieces, you could exchange them. but you could mount them 2 ways, with the positive on the inside and negative on the outside, or visa versa. http://www.yagoda.nl/yagoda-advertenties/images/Universele%20Laptop%2060W%20lader/1.jpg

Of course after a month or so he pulled on the wire and the connector piece was lose. he (not knowing)just put it back. But on the wrong side, and he toasted his laptop.

 

I forgot about this thread and have just read the replies. I am not after an universal adapter, but was hoping that there was some little gem of a company out there that did aftermarket adapters for specific models.

I thought that by using more expensive/better quality components they would be able (for a premium) to make them smaller.

 

I'm not sure smaller is better. I don't have a whole lot of laptop experience but, while my wife's couple of year old HP ZV6000's ac adapter get's warm and is about 1.5-2x physically larger (not sure of wattage) my new laptop HP/Compaq V6500Z has a physically smaller, 65W adapter and it gets extremely hot if you are charging or running at max. performance. It kind of concerns me it gets so hot. When I can, I run a fan on it to dissipate the heat!

 

Why couldn't they make at least one side of the adapter out of metal to act as a heat sink?

 

I think it has something to do with the fact that they have to be double insulated and therefore metal is no good.

 

Put an insulator between the metal and the parts inside.
Of which, it seems like just gluing a heatsink to the plastic case can be enough to make an improvement.
