A portable refrigeration container is usable for cooling a bottle of drinkable fluid. It includes a tubular body, a vortex tube, an electronic programmable controller, a tank of compressed air, a battery, a Peltier device, a heat exchanger, and a removable electrical charging station. Optionally, the portable refrigeration container further includes a compressor, a dynamo, and a bracket for attachment to a bicycle frame. The optional compressor and dynamo that electrically recharges the battery, may share a single shaft that is rotatably connected to turn with a bicycle wheel.
