From the Manufacturer:
The first electric cooler with its own ice maker – with a rapid freeze plate that makes ice in just a few hours, without compromising the temperature elsewhere. Reaching temperatures as low as -7°F, while using less power than a 60W light bulb, the car fridge freezer can be powered by AC (110-240), DC (12 volt / 24 volt), or solar. The tallest fridge cooler in the CFX3 series, the 55IM is constructed with lightweight fender frames and strong aluminum alloy handles, while the high-performance compressor is built with noise and vibration reduction.
