Power inverter in 2021 320 12-volt outlet....

So I'm assuming, I know....assuming, that the cigarette lighter-type input in the 12-volt outlet could be for a power inverter like I've used in my cars for years mosty to charge batteries and phones and power up computers and camera equipment.
Is my assumption correct? If so, what's the maximum size I could use?

    The 12V outlets are on a 15V fuse.  In theory, you could draw 180 watts from them.  In practice, it would be better to go only to 80 percent of that, so "about" 145 watts.  I use small inverters (300 watts or less) in the trailer in the exact way you describe.  You will get a little more bang for your battery if you use a 12v adapter for your laptop.
