Is there a distinction between single-core and dual-core for car refrigerators?
2 Answers
Car refrigerators generally do not have a distinction between single-core and dual-core; they only have single-cycle and multi-cycle systems. Here are the advantages of car refrigerators: 1. Shock and vibration resistance: Car refrigerators have excellent shock resistance, making them suitable for use on bumpy roads; 2. Battery protection: Car refrigerators will automatically power off when reaching the set battery protection value, ensuring normal car startup; 3. E-mark (electromagnetic interference): The electronic control module of car refrigerators does not interfere with other electronic products in the car during operation, nor does it affect the normal use of the car battery; 4. Anti-tip protection: When using a car refrigerator, slight tilting does not affect normal operation, but when the tilt reaches 45° or more, it will automatically stop working to protect the compressor.
I also struggled with this issue when buying a car refrigerator and found that there's no such thing as single-core or dual-core in the market. Car refrigerators are mainly divided into two types: compressor-based and semiconductor-based. Compressor refrigerators have strong cooling capabilities, like a small fridge, suitable for long trips to store drinks and food, but they are slightly more expensive. Semiconductor ones are quieter and more compact, ideal for short trips with some cold drinks, but their cooling performance in summer is average. When choosing, consider your needs—compressor types are more reliable but consume more power. I recommend compressor-based ones; I've used mine for two years without any issues. Also, pay attention to power matching with the car cigarette lighter voltage to avoid battery over-discharge—safety first. If you're on a budget, semiconductor types are also good, costing just over two hundred yuan. Read more reviews and don't be fooled by fancy terms from merchants.
