Abstract: A cooler apparatus is disclosed having an onboard air conditioning assembly. The apparatus may be used to retain and chill food and beverages while simultaneously functioning to cool the surrounding environment. The air conditioner assembly may include a radiator positioned on or in a wall of a housing and an exhaust fan positioned to circulate air through the radiator. A source of air may be provided to the exhaust fan by an air intake fan. Additionally, a fluid reservoir containing a coolant for the radiator may be provided that includes at least one surface positioned proximate the interior of the housing. The coolant may thus be chilled by adding a predetermined quantity of ice to the interior of the housing and the chilled coolant may then be circulated between the reservoir and the radiator by a pump.
