Aspire 5552 - Charger

Hey there.

I'm looking to find a replacement charger for an old laptop I have to give to a friend, and it's kind of difficult when the bottom of the computer, the charger, and the battery all have different readings.

Computer..

PC: Acer Aspire 5552-7819

Model No: PEW76

*Near this information it says "DC Rating: 19V --- 3.42A"

Battery..

ID: AS10D41 (3ICR19/66-2)

Lithium Ion Battery Pack (Li-Lion 20)

* "Rating: 10.8V --- 4400mAh"

Charger..

LITEON

Model: PA-1900-32

Input: 100-240V ~ 1.5A 50-60Hz

Output: 19V --- 4.74A

I did spent a lot of time searching this on the internet and found some chargers on Newegg and such that could be compatitable; I just don't want to buy a new charger and have it cause problems, so I'm looking for some specific charger(s) that could work for this computer.

Here is the closest charger that I could find..

It says it is compatible and everything, but the specifications don't match my old one.. at least, I think.. I really don't have a clue how the different voltage/amp descriptions tie together.
