Yes, all the Jay Flight models have a 120V AC and 12V DC electrical system.
The lights are 12V and can run off the battery when boondocking, or off 120v shore power (converter/charger converts 120V AC to 12V DC where applicable).
As mentioned the frig will operate on 120V AC shore power or LP, but in both cases it requires 12v DC power (battery) to operate the frig's circuit board/light.
The Jay Flight frig will not operate solely on 12V DC battery power.
