Abstract: Systems, methods, and devices may include a cooled storage system with a case having an outer bucket with a first bottom wall and a first sidewall. The outer bucket may include a flange protruding from the first sidewall. An inner bucket may be disposed at least partially within the outer bucket and may include a second bottom wall and a second sidewall defining a storage compartment in the case. A coil may be at least partially disposed in the volume between the inner bucket and the outer bucket with a phase-change material disposed about the coil. An electronic control system may actively and passively cool the storage compartment resulting in extremely efficient and precise temperature control.
