Why is the FridgeFreeze more efficient than other portable fridge/ freezers?
The FridgeFreeze is so efficient because it uses the entire outside casing as the condenser to dissipate heat. This is possible because the casing is made of marine grade aluminum. All other portable fridge/ freezers use a fan and an external condenser. The problem with this method is that a fan increases the amp draw and the external condenser is susceptible to corrosion and breakage.
