dv6 power adapter?

I am thinking of buying the dv6 Quad Edition which says that it uses a 120W power adapter. Because I will carry the laptop to and from work every day, I pretty much need 2 power adapters (particularly since depending on where I am stationed, work and home sometimes use different types of power outlets...). HP's 120W adapter is expensive ($81) and currently out of stock. I found this one on Amazon which is at half the price. It looks identical to what HP is selling and the Amazon comments say that it works.

Does anyone know why the one HP sells is so much more expensive? Is this just another case of a manufacturer trying to milk people who don't use Google for all they're worth?

 

I carry HP's Auto/AC/Air 90w adapter, in my bag, for everyday stuff. HP lists it as compatible. The 120w adapter that came with the notebook, stays at home for use when it is docked. I do not do anything taxing graphics-wise with my dv6tqe so I am not too worried over forking even more money just to adaquetly power the ATi GPU when I have the notebook away from home. Of which, when it is, nine times out of ten, it is on battery power anyway - I run the Intel GPU in that instance.

So I suppose, you might want to consider how you use your notebook. Are you mobile with it often? Are you in a situation where you need it plugged it to complete your daily tasks? If you are worried strictly over the build quality of the generic adapter on Amazon, then condsider that your unit is on warranty. Playing the odds here: consider that HP will void your warranty if any damage should occur to your notebook by using third-party devices. That is a remote chance but it still exsists, nonetheless. I would wager that the Amazon adapter is a safe purchase, but hey - s@#t happens.

 

I got this for my DV6: Antec SNP90

120W is the absolute max power consumption (with the AMD and CPU running at max), but in nearly every situation a 90W adapter is sufficient. The Antec SNP90 I got works great, is very light (0.44lb compared to stock's 1.2lb) and very thin.. thinner than the laptop itself.
