2. The portable cooler container system of claim 1 , wherein the conduit extends along a coiled path.

3. The portable cooler container system of claim 1 , further comprising one or more sensors configured to sense one or more parameters of the payload chamber or temperature control system and to communicate the sensed one or more parameters to the circuitry, the circuitry being further configured to operate the thermoelectric module based at least in part on the sensed one or more parameters.

4. The portable cooler container system of claim 3 , wherein at least one of the one or more sensors is a temperature sensor configured to sense a temperature in the payload chamber and to communicate the sensed temperature to the circuitry, the circuitry being further configured to operate the thermoelectric module based at least in part on the sensed temperature.

5. The portable cooler container system of claim 1 , further comprising one or more fins extending from the outer surface of the conduit.
