Laptop Adapter compatibility

danyjr · 1 Oct 2007 at 20:22

Hey guys, I've posted a thread a few days ago regarding my laptop. I just found out that the adapter is damaged so I want to buy a new one.

But before I want to buy it I want to check whether my friend's laptop adapter works on mine or not.

My original laptop adapter:

OUTPUT:
19 V , 4.74 A

My friend's laptop adapter:

OUTPUT:
19 V , 3.42 A

As you can see they have different output currents. Does that mean it is dangerous if I plug my mate's adapter to mine? Or will it be okay and work fine as well?

Thanks for your comments!

It will work but it won't charge properly.

Thanks for the response, just one question:

Will it damage the battery if I use the 3.42A adapter?

Hello Mate,

I would not try it, i don't think a PSU with Less Amps will have enough to power it

Saying that, you might actually overwork the power supply and cause that to burn out as it can't deliver the amps needed.

For a short runs it would still work but won't charge the battery.
