Unless he can regulate that DC to the exact voltage (18.5-19.5) required by the laptop, it would be safer to get an inverter and use that to feed the AC adapter that came with the laptop.

I have a person who is off-grid and wants to run his laptop off the DC power he produces. Is there a device that will let him bypass the power adapter that comes with the laptop to do this and is it recommended?
