Abstract: The invention is a portable refrigerator (10) that may transition between a functional mode for use in the cold storage of food and drinks and a collapsed mode for transportation. Wheels (207) with a handle (52) opposite provide the method of transportation. The food storage space is controllably cooled by a chiller circuit (60), which may be powered by one or more solar panels (10). The device includes USB and A/C outlets (202,206) so that the device can be also be used as a power source. It may also include a lockable latch (203) to keep the refrigerator space closed. It may also include a u-shaped bar (200) on the outside so that the device can be secured to a fixed object.

Abstract: A portable refrigerator transitionable between a functional mode and a collapsed mode for use in the cold storage of foodstuffs or drinks comprising a chiller circuit, and a front wall, a rear wall, a top wall, a base, and at least a pair of sidewalls combined together to enclose a storage space when the portable refrigerator is in the functional mode, wherein the storage space is controllably cooled by the chiller circuit, and wherein the front wall, the rear wall, the top wall and the side walls are inwardly foldable to form a compact package when the portable refrigerator is in the collapsed mode, and wherein the top wall comprises one or more solar panels thereon.

Abstract: A novel portable refrigerator is disclosed where the refrigerator is collapsible for storage, comprising a foldable panels for a top, sidewalls, a front, a rear and where all of the panels are attached to a base. One of the panels further includes a chiller circuit that is capable of recirculating the air contained with the refrigerator and cooling it to a selected set point. When in the collapsed mode, the collapsible refrigerator is securable and can be easily handled by the user and stored in a convenient manner.
