You can buy commercial 12V to 115V/230V converters. They are often called inverters. They will deliver the correct voltage for your notebook power supply. Also, you can use it for other things too - depending on why/what/where you want to recharge your notebook.

I'm sorry, I don't have a schematic for a DC voltage converter.

Hi
Get from Internet LT1071 datasheet and make it.
I was make and it work 100% good.

I was get idea from one fabric supply 12 to 16V for toshiba laptop what i was service.
Simple I was clone it and after that I was download datasheet and from that moment
I only use it for connverters DC to DC.
You will have 3 amp without external power transistor !

Regards

Here is the article for 12-19V/5A converter. It can be modified for lower output voltage.

Try this circuit. Play with duty to get 16v under load.
You may add load resistor to avoid open circuit voltage jump.
