What is the typical power consumption of a car refrigerator?
2 Answers
Under normal cooling mode, a 12L car refrigerator typically consumes around 60W of power, which is equivalent to the power consumption of a car navigation system. Here is relevant information: Car Refrigerator: A car refrigerator refers to a portable cooling appliance that can be carried in vehicles. It has become a popular new generation cooling and refrigeration device in international markets in recent years. Working Principle: Car refrigerators are an extension of household refrigerators, utilizing either semiconductor electronic cooling technology or compressor-based refrigeration. They generally operate with low noise and minimal pollution. During travel, simply plugging the power connector into the cigarette lighter socket can provide cooling for the refrigerator.
The power of car refrigerators generally fluctuates between 40 to 100 watts, depending on their type and size. I've used many car refrigerators - compressor-cooled ones typically have lower power around 40-60 watts, cooling quickly while being energy-efficient; thermoelectric semiconductor types have higher power reaching 70-100 watts, but with lower efficiency and slower cooling. It's important to note that cars use a 12V DC system, and standard car cigarette lighter sockets typically support 60-100 watts maximum. Too high power may blow fuses or drain the battery too quickly, affecting engine startup. I recommend choosing medium-power models between 50-70 watts for balanced practicality and safety. Larger capacity refrigerators naturally have higher power, while small portable ones can work well with just 40 watts. For camping trips, I often choose a 55-watt model that can run all day without worrying about draining the car battery - very convenient.
