Q:Does the fridge charge the oil?: In fact, the power of the car refrigerator only tens of watts, equivalent to a lamp power consumption. When the car engine starts, the car generator power to the battery charge, when the battery is full, no generator is also a waste of electricity, car refrigerator is to use surplus, do not increase fuel consumption!

Q:Is it easy to use the car refrigerator? How much is the car refrigerator?: There are two kinds of car refrigerator on the market, one is hot and cold box, affected by the ambient temperature, can be heating and cooling. But the cooling effect is not ideal. So it is not recommended. Another car refrigerator is a car compressor refrigerator, a good brand generally refrigerated up to - 18 °, and the temperature is adjustable, very good.

Q:Intend to buy a small refrigerator, it was said to increase fuel consumption, it was said that when driving the power is actually wasted, not clear: Car refrigerator is divided into two kinds. With power and no power, with the power of the comparison of fuel consumption, no power supply weight more power consumption.

Q:Does the car refrigerator need to go through the electricity?: There are two kinds of car refrigerator on the market, one is the semiconductor car refrigerator, its principle is to rely on electronic chip cooling, the use of special semiconductor materials constitute the PN junction, the formation of thermocouple pairs, resulting in Peltier effect, that is, by DC cooling A new type of refrigeration method. The cooling temperature range is 5 to 65 degrees. The advantages of this refrigerator is both cooling and heating, environmental protection, pollution-free, small size, low cost, work without vibration, noise, long life. The disadvantage is that the cooling efficiency is not high, the cooling temperature is affected by the ambient temperature, the cooling can not reach below zero, and the capacity is small. The other is the compressor refrigerator, the compressor is the traditional traditional refrigerator technology, cooling temperature is low, -18 degrees 10 degrees. Cooling efficiency, can ice, fresh, large size, is the future direction of the development of car refrigerator. But this weight is heavy, easy to carry, the price is higher. Compressor Car refrigerator compressor The world's leading producer for Germany and Japan.

Q:What brand of car refrigerator is best to buy?: The cost of electricity is very small, only tens of watts, but also convenient, hot days do not want to get off to buy water should have a

Q:My small refrigerator is Haier, you can run under 220v 5 hours, but can not be used for a long time, how can the refrigerator at home to play a role? Need DC 12v, power in the 38-48w. What kind of transformer does a DC power cord need to use? Or how to do? consult!: Can go to the electronic components shopping malls (market) to buy a 220V / 12V, 50 watts of power transformers, and a 4 amp rectifier bridge pile, plus two 10000 microfarad, 50V capacitor can be used as a 12V, 4A that is 50 watts of DC power, and all costs about 15-20 yuan.

Q:What kind of car refrigerator is better?: Car refrigerator is divided into two kinds, one can be cooled to 0 ℃ below the car refrigerator, another car with a cold box, electronic hot and cold boxes and other cooling effects are generally maintained at about 5 ℃, can not ice, ice cream Need frozen items can only be temporarily stored, the above two categories are called car refrigerator, as to what kind of good, or to see which is more suitable for their own needs.

Q:The principle of car refrigerator: Car refrigerator is the principle of working with the semiconductor cooling, small size, low weight, no noise, easy to carry, but the temperature can be reduced to about 4 degrees Celsius, generally only for cold storage. In addition, if the power supply can be connected to heat.
