Abstract
A portable thermoelectric device includes a thermoelectric cooler; a probe configured to measure a temperature inside the device; a compartment fan configured to circulate air in the device, the air having been cooled by a cold side of the thermoelectric cooler; an exhaust fan at least partially positioned in the device and in communication with an external environment, such that the exhaust fan is configured to vent heat from a hot side to the external environment; and a power source configured to receive a range of input voltages. In some embodiments, a first input voltage results in a first temperature differential between an internal environment in the device and the external environment and a second input voltage results in a second temperature differential between the internal environment and the external environment.
