Product review (4 stars): Like an evaporative cooler they only drop the outside ambient ...
Let me first start by saying that this is based on a peltier device.  Peltier devices are highly inefficient! Like an evaporative cooler they only drop the outside ambient temperature by 30 to 40 degrees in the compartment.  So if it's 110 degrees outside of the fridge, that means the coldest the compartment can get is 70 degrees.  That's less than ideal if you want cold sodas or brewskis.  This fridge has no compressor - if you want your drinks to be efficiently cooled, then get a mini-fridge with a compressor - they will do a better job.  The benefits of this fridge are that is is light, it can run off of a battery, and it will chill your beverages providing that the outside temperature is between 70 to 80 degrees.  Yes, the fan will run continously kind of like a desktop computer.  But that can be expected considering that a peltier device is a semiconductor like a cpu.
