A portable cooler has at least three separate storage compartments that comprise at least one ice-cold storage compartment; at least one dry moderately cold storage compartment; and at least one dry non-cold storage compartment. A temperature gradient construction enables the user to proficiently store food and non-food items of varying water sensitivities and temperature needs. Typically, a wet cooling medium is added to the ice-cold storage compartment. Discrete thermal conduction pathways extend from the ice-cold storage compartment into the moderately cold storage compartment, cooling the moderately cold storage compartment. The less cold compartment and the non-cold compartment are completely dry of water. Each of the compartments has its own lid enabling selective entry and thereby preventing temperature fluctuations and moister transfer when another compartment is accessed. The portable cooler has a plurality of foldable wheels on the base thereof to facilitate portability.
