Founded in 2002 and headquartered in Beijing, Aotsai only began to launch a series of compressor car refrigerators in 2008. However, Aotesai has made achievements in the field of car refrigerators, and its full range of compressor refrigerators use German SECOP DC inverter compressors, with reliable performance, and in the field of semiconductor refrigerator products, it is also the first to propose and develop dual refrigeration/heating electronics series car refrigerators.
 
Aotsai car refrigerator products include compressor refrigerators and semiconductor refrigerators, from 7.5L small-capacity products to 49L large-capacity products have a layout, the product line is relatively complete, high-end car compressor refrigerators are mainly ATS series, all of which use German SECOP compressors, which can still operate normally at a 35° inclination angle; The semiconductor refrigerator product line is relatively messy, and there is no systematic series of product lines.
 
Compared with foreign brands such as Indel and Meigu, the price advantage of Aotsai in the small capacity products below 15L is not large, but it has a relatively obvious price advantage in the capacity of 25L and above, such as ATS-B-25P, ATS-B-30P, due to the use of German compressors, strong performance, large capacity demand, and relatively limited budget users can consider purchasing.
 
Semiconductor refrigerators can be considered 1178/1189/1199, from the price point of view, the three are relatively high-end in the product line of Ottsai semiconductor refrigerators, belonging to the same series, except for different capacities, there are no other functional differences, dual power supply design, no additional adapters can be used at home, and there are no obvious highlights in performance, which is at the market average.
