Laptop Car Adapter Will Generic Car Power Adapter With Slightly Different Voltage Damage My Laptop/notebook?

Will generic car power adapter with slightly different voltage damage my laptop/notebook? - laptop car adapter

I have a Compaq Presario V5310us. The power supply says:

INPUT: INPUT wide range (in particular the ac in each country)
OUTPUT: 18.5 (18.5) = 3.5A (3.5A) 65W

The generic car laptop power supply, the following voltage options were also bought:
Input: 11-14V DC MAX 8AMP
OUTPUT: (selectable) 15/16/18 / / 20V DC 4A
22/24v DC 3.3A 80W max.


What voltage should I choose? and is there a risk?
He was with a DC-AC in the car with the power cord to the laptop, but it seems simple and, it might take less load on the battery?
