A well-known brand in the United States, including more than 200 product lines including car refrigerators, has a strong industrial support, and the overall strength is needless to say, but because the products are mainly sold in the North American market and have not entered the domestic market, they need to be transferred by overseas shopping, and it is relatively difficult to buy, and it is not well-known in China.
 
Koolatron covers the product line of compressor refrigerators and semiconductor refrigerators, but its compressor refrigerators are designed for heavy-duty trucks or household use, with relatively large capacity sizes, and the general consumer market is still dominated by semiconductor refrigerators. For example, the 45L capacity BC-46SS Kool compressor refrigerator on sale, weighing 20 kg, basically gives up portability, and can only be used in large and medium-sized cars with plenty of space, with relatively large limitations, and the minimum refrigeration temperature can only reach -2 °C, and the performance is relatively average.
 
Semiconductor refrigerator recommends KCR40B, although there is no compressor, but the use of special R134A refrigerant, refrigeration capacity is better than ordinary semiconductor refrigerator, can reach 30 °C lower than the ambient temperature, the performance of the general semiconductor refrigerator is much better, but the price of about 1400 yuan is much higher than the price of about 500 yuan of the general semiconductor refrigerator, counting freight and tax, the cost is not lower than some small and medium-capacity compressor refrigerators. KCR40B is the same as BC-46SS Kool, the weight and volume are relatively large, and the large capacity of 48L may not be suitable for most people, so you must confirm whether the interior space is enough before buying.
 
The small-capacity product is KWCXJ6 Coca-Cola, a customized product of Coca-Cola, which can put 9 bottles of 350ml drinks, and has a built-in self-locking door design, which is very necessary for a portable refrigerator, which can effectively prevent the door from opening automatically due to poor closure during the movement, but the box capacity is only 7L, which is slightly smaller, and is more suitable for short-distance commuting.
 
Compared with other brands, Koolatron's products do not have a particularly significant advantage in price and performance, but as a well-known American brand, its quality is still guaranteed, and it has partnerships with the world's top companies such as Coca-Cola to launch its customized products.
