I'm searching for a second power source for my HP laptop but trying to
avoid the high OEM cost. Therefore, I've been searching for aftermarket
adapters which don't quite match-up to the exact specs of the OEM.
The OEM specs are as followed:
input: 100-240v~50-60Hz 2.0A
I have found aftermarkets with specs of 100-240v~50-60Hz (input) and
That minor 1v less and .35A more of a difference in output is what makes
me apprehensive. Am I being overcautious or is it a legit concern?
Your probably fine. The output voltage can be a little low. Low is better then
too high. The output cut tent is the rating so equal to or higher is fine.
The most important thing to check is the polarity of the connector. Most are -
for the outer ring and + for the inner pin. Make SURE the new one matches the
old one BEFORE you plug it into your computer. Also make sure the connect is
the same size..
amperage It doesn't matter if the amperage output is higher. The voltage,
however, should be identical. You might get away with the 1V difference,
but I don't recommend it.
Take a look at priorityelectronics.com (I have no connection to them
except as a customer). You should find a good quality exact spec 3rd party
replacement there at much less cost than OEM.
Go to ebay and search for HP laptop power adapters. You will find
many. And even the <$10 ones mfgd in China work quite well. I've had
to replace a lot of HP power adapters and these inexpensive ones work
as well and longer than the OEM's.

I have a "rocketfish" (best buy house brand) universal brick that works
on pretty much everything, it also will run directly off 12VDC which is
nice for mobile use. It appears to have been discontinued but this one
appears to be even better as it is a 120W supply rather than 90W as is
mine. If you can confirm that that will work for your laptop I would
buy that one as likely you will be able to repurpose it after your
laptop is obsolete.
replace "roosters" with "cox" to reply.
I respectfully disagree. Those $10 adapters from eBay and Amazon are very
poor quality. Some tend to run so hot they may be a fire hazard. They also
often fail within a few months. They lack proper overload protection and
can, though it is rare, damage a laptop. As a technician I would never buy
nor recommend them for my customers.
It may depend on what you buy. I bough one for less than $15 that was new
and for a Dell. It has all the Dell markings on it and I would think it is
made for them. It was for the exect model that I have.
If the origional poster would have given the model he has, that would have
been a big help.
