This is not a fishing question, but with the knowledge of electronics on the board I hope someone could help me out.

I want to get a small refrigator to use on a pontoon or in my truck camper shell for over night or longer trips. I have looked at the 12v models but have found that 110v models offer more space and are less in cost. I know that the larger the unit the more power it will take to cool. I would like to know if the 110v unit running off an inverter will take more power from the battery to operate than a 12v assuming both units are equal in size and cooling capacity. Has anyone tried using an inverter for this type of power source???Any experiences or information will be appreciated.
