Our Chevy has a 115 volt socket in the dash using a built-in inverter; it is active while underway.
If you don't have the socket in your dash, as mentioned, get an inexpensive inverter to plug into a lighter socket, or better yet, get a good Pure Sine Wave inverter and hard-wire it to the batteries. Ensure you've turned it off while you are not using your unit - the parasitic draw will drain your batteries unless you have the unit plugged in.
A PSW inverter is compatible with anything AC (up to the rated wattage), where a MSW (Modified Sine Wave) may not. I have some AC devices that do not work with MSW.
