Product review (4 stars): Good product, but it does have limitations
I like this cooler. It fulfilled my needs and expectations, but it does have limitations. This review will concentrate on those limitations, which may make the review seem to be more negative than my rating. But I really do feel it deserves 4 stars. I am not fond of fishing in an ice chest for a can of beer. I wanted something a little more elegant for patio parties. That is why I bought this cooler, and it meets that need.
This cooler holds 5 liter mini-kegs. That is 1.32 gallons or 169 fl.oz. - or about 14 glasses of beer. You should plan on changing the mini-keg during the course of a party. However, quick disconnects are used, so keg change is quick and easy.
This cooler is not very efficient - either in power use or cooling capacity. The power draw is stated as 65W, which is about 40% of the power drawn by my full-size refrigerator. However, the cooling capacity is minuscule compared to a refrigerator. The cooler will keep a keg cold, but it takes most of a day to cool down a warm keg. You will want to pre-cool your kegs in a refrigerator - especially kegs that will be changed during a party. The minimum set temperature is 36F, which is where I have mine set. The cooler shuts off at 38F and restarts at 41F.
The hoses used are small diameter, so the fluid stream is "weak". It takes about 40 seconds to dispense a 12oz glass of beer. Increasing the keg pressure does not materially increase the flow rate, but it does increase the amount of foam on the beer. The CO2 pressure regulator should be set fairly low for a "normal" amount of foam. This is plain physics, not the fault of the cooler. When the keg is under pressure, CO2 dissolves into the liquid - which then reappears as foam when the beer is dispensed. Lower pressure, less foam.
This cooler apparently uses a Peltier effect solid-state cooling module, so the only moving part of the system is the ventilation fan. The fan is louder than the fans used in tower-format desktop computers, but it is not objectionable. Outside on the patio, you have to listen hard to hear it. It is necessary to add water inside the cooler, so the keg is sitting in water. Presumably, the purpose of this water is to improve the energy transfer from the keg to the Peltier module. However, a quick drain tap is provided, so removing the water is easy.
The power cord is short, so you will need to place the cooler near an outlet or use an extension cord.
My one real complaint about this cooler is that the power cord is ungrounded - 2 wire. Seems to me this presents a safety hazard for an appliance that likely will be used outdoors. I could be wrong, but I don't think a GFCI outlet or breaker will trip, under ground fault conditions, unless the appliance has the third wire (dedicated ground). The cooler has metal sides. The metal kegs sit in water that also is in contact with the Peltier module. I definitely would feel more comfortable if the cooler was grounded and had a contact to ground the keg as well. I plan to unplug the cooler each time I change the keg.
