I purchased a Koolatron cooler and noted that the manual stated that non-Koolatron AC/DC adaptors should not be used and would void the warranty. Rather than take the chance with my old adaptor from a different brand electric cooler, I decided to order a new one. Koolatron offers its adaptor at its web site and I just about ordered it, but then compared Amazon's offering. The identical adaptor at Amazon is half the price of the one through Koolatron. I've used it a number of times and it works fine. It also has about twice the wattage capability of my old adaptor. One caution: the cooler cools or heats depending on how the adaptor or DC plug is connected to the cooler cord. Tell everyone who might use the cooler about this. I failed to tell my wife, and she thought she was cooling a load of food, when, in fact, she was heating it. Big mess.
