Abstract: A mobile storage apparatus includes a cabinet having an insulated, closable storage chamber adapted to accommodate one or more objects in a temperature controlled environment. The cabinet also has or associated with a system for changing a temperature level of the storage chamber when the system is powered by a power supply. A storage chamber liner is provided and preferably formed from thin, sheet-form material arranged within the chamber adjacent one or more sides of the chamber, but spaced from one or more sides such that the liner divides a volume of the storage chamber into a main central volume for accommodating one or more objects in a temperature controlled environment and a minor peripheral volume for receiving one or more thermally conductive passive temperature control devices.
