A practical solution for travelers with special dietsMy wife and I eat kosher food exclusively, so our ability to travel outside areas where kosher food is readily available is limited by our ability to carry perishable kosher foods with us and store it safely. This limited us to the amount of food that would fit in a portable car cooler, using ice or frozen ice packs from home, and generally limited us to overnight stopovers and destinations where a refrigerator was available. But the recent addition of the dual voltage Euhomy car/home refrigerator-freezer has vastly expanded our travel horizons. It easily maintains a constant (within 5 degrees) temperature of our choosing running off the car battery, or in our hotel room running off a standard 110-volt wall outlet. It can safely store frozen foods at temperatures as low as -4 degrees Farenheit, and comes with a removable partition that divides it into a small refrigerated section alongside the larger freezer compartment.The sturdily built unit has two small folding carrying handles, as well as two wheels and a longer handle for rolling the unit instead of having to lift and carry it. At about 35 pounds empty, the 37 Quart size is light enough to be manageable by one strong person, and relatively easily by two people, even when loaded with food. It fits easily on the back seat of even a small car. The supplied 12/24-volt cable is long enough to easily reach the car-lighter power jack found in the front dashboard of most vehicles. The unit also comes with a relatively short, 3-prong 110/220-volt AC power adapter and cord.The unit's functions are controlled by an electronic touch-sensitive display panel, with a current temperature readout for the internal compartment(s). An automatic child safety lock must be disabled before entering any commands. There isThe temperature can be varied in 1-degree increments. There is an adjustable setting to protect the car battery from its charge being depleted when the car motor is not running, and a convenience light inside the folding top lid.The brief instruction book is written in passable English with FAQ and troubleshooting sections in addition to describing all basic operations. Learning to use the touch screen controls efficiently does take some practice.On our first trip with the unit, we found it large enough to hold at least 3-days worth of food. When the compressor is running, our unit does make a slight rattling noise, but it was not loud enough to be noticeable when driving at highway speeds, nor did it disturb our sleep while running overnight on the floor of our hotel room.The unit has two power levels, 60 or 45 watts. At high power, it cooled the empty food compartment from room temperature to the set level in less than half an hour.While the ability to use the unit as a refrigerator and freezer simultaneously is convenient, in that configuration, the temperature control affects only the freezer compartment.In the refrigerator-only configuration, the unit is big enough to store up to a half-gallon milk bottle upright, but when the partition is in place, the fridge section can only store smaller diameter bottles upright, because most of the lower part of the compartment is taken up by the motor housing. In light of the space taken up by the motor, we were wise not to buy the 22-quart Euhomy unit that we had first considered, because it would not have had enough food storage capacity to meet our needs.33
