Laptop chargers lie generally. they deviate by as much as 1 volt.
That being said the voltage doesnt matter much as almost every laptop out there accepts a fairly wide voltage range. You really have to find the detailed technical specs on the laptop to find out what it accepts. HP has some of them(which is how I found out my laptop doesnt charge the battery at <15volts)
My HP laptop will work down to 13 volts, but anything under 15 volts and the battery wont charge(protection circuit)
If your brick says 19.5 you run can almost always run 17.5/18/18.5/19/20 safely. Look up universal power bricks that support your laptops model. More often than not they wont be the same voltage as the OEM brick.
