Abstract
A mobile cooler including a compartment having pivotable wheels and a handle assembly for pulling the cooler. A pair of wheel assemblies individually pivot within recesses in the cooler from a raised to a lowered position. In the lowered position the cooler can be transported over smooth or uneven terrain. The handle telescopes partly into the compartment, and partly folds down by a pair of hinges to fit within recesses in the compartment lid. The handle length can be adjusted to suit the user.
