Where might I find a 12v DC power cord for use w/ my hp elitebook 8440p laptop. I moved into my RV full time for now and am thinking I should be able to run my laptop dc to dc from the house (RV) batteries. yes? where does one find a non-ac adapter power cord?

thanks

Hi


Does your laptop run at 12 V?
Most I see run at 15V to 19V

You see cigarette lighter adapters for 5V usb
I had one for an ancient Samsung Q1 tablet

Unless you have a commercial vehicle at 24 V or 3 x 6 v batteries it may be cheaper to get an inverter to produce mains voltage rated at about 120 watts
Hopefully your laptop has a 60W or 90W psu
