Hello,

I own an Asus G53 notebook, and since it's so heavy and I don't really move it much, I removed the battery because I always have it plugged in and figured that all the heat going to the batter wouldn't be good for the batter life. So I always have it plugged in AC only. The other day while I was playing a game, my laptop randomly shut off and the ac adapter led button wasn't turning on when I plugged it in. So I figured it died as the laptop still runs when I put the battery back in.

Now I am looking for a replacement for an adapter and have this dillemma.
The specs of the adapter I got with the laptop reads
Input: 100-240V ~ 2A
Output: 19.5V - 7.7A

Now I found this other Adapter online and it has my laptop model listed under the supported models however the output reads a little different as
Output: 19V - 7.9A

Now I am not very good at all this electrial stuff and not sure if I should buy this adapter. That's why I am asking the community to point me to right direction or enlighten me in this topic. Any help would be appreciated.

A difference of .2 amps isn't going to make a difference. The quality of the adapter will make a much bigger difference. Also, you might be putting extra stress on the AC adapter by not running a battery in the laptop. The battery can supply peak current much easier then AC adapters can, as the latter's output is limited to their rating. Batteries normally run far lower then what headroom they have, so when an extra amp or two is needed, because the game you are playing demands it, the power will be there if the battery is installed.

Not the exact same one, but similar to it.
