HADave, if I understand correctly, those piezoelectric coolers function by cooling its contents to a fixed amount of degrees Farenheit below the ambient air temp. I think that amount is typically something like 20 degrees, which works to keep perishables viable in cooler temps, but may not be suitable for very long term cooling in Hawaii or where you need lower temps. It would certainly be better than nothing. We used one on a car trip in May in Arizona, and it did perform adequately. I don't know how the high temperature with low humidity compares to the medium-high temps with high humidity with regards to this kind of cooler.
We used to own a VW Eurovan MV which came with this type of cooler. It ran off the auxilliary battery which needs to be a deep cycle marine battery. Your regular car battery may not last very long running one of these once your car engine is turned off.
