i am designing a 12V mobile coolbox, which has a 25L ineterior cabinet. enough for holding 24 bottles of beer. The objective is to get is as cold as possible and as small and light as possible. So i descided that it is going to be a compressor coolbox. The compressor has to be as light as possible. I searched for lightweight compressors and the only two big companies that make them seam to be Aspen and Danfoss. The smallest of the two are Aspen compressors. My conserns are that the compressor is not good quality if i buy it from another that the marketleader danfoss. Is Aspen also good?
