Summit Appliance brings advanced convenience to on-the-go refrigeration with the SPRF56, a fully featured portable cooler that can be set at refrigerator or freezer temperatures for use while camping, tailgating, roadtripping, and similar activities. This lightweight compressor-operated unit can be plugged into the 12V DC lighter socket inside any car, truck, RV, or boat, as well as 24V sources. We also include an AC adapter to allow the SPRF56 to be plugged into a 120V electrical wall outlet. It has a gray plastic exterior for added durability, while an insulated fabric cover is included to help preserve the cool interior and protect the exterior during transport. Handles are located on each side for easier lifting as needed. The SPRF56 can hold up to 55 liters with two compartments for convenient storage. The larger left compartment can serve as a refrigerator or freezer, with a hammered aluminum interior for added insulation. A wire basket is included for convenient transport of contents. The right compartment is non-refrigerated but when the larger compartment is running will reach temperatures between 40-55(degree)F, perfect for storing produce, bread, butter, and non-perishable items for added convenience. A digital thermostat with an external LED thermometer display allows easy temperature control without requiring users to open the lid. With a versatile design and reliable storage conditions, the SPRF56 brings new levels of convenience to portable cooling for users whether at home or on-the-go. NOTE: Accucold refrigerators are purpose-built to the support meeting the current CDC (Centers for Disease Control) guidelines for the storage of vaccines. At this time, Accucold refrigerators have not been evaluated to the new NSF 456 standard. For additional temperature assurance, the CDC recommends a calibrated digital data logger (DDL), which can be added with the purchase of a DLSA11CAL accessory.
