(Why don't we show the price?)

Retailers have the legal right to set their own prices, but some manufacturers place restrictions on how those prices may be communicated. Because our price on this item is lower than the manufacturer's “minimum advertised price,” the manufacturer does not allow us to show you our price until you place the item in your cart, or in some cases, proceeding to the final checkout stage. Taking these steps allows Appliances Connection to show you our price consistent with our goal of always offering you the lowest possible prices on the widest selection of products. You are not required to purchase the product to see our lowest price, simply just remove it from your cart.

This compact fridge works on 12 V AC or 110 AC power and uses just six amps of current when operating on your vehicle’s 12 volt power.

The Compact Flush-Back Design
Makes it an easy fit in small spaces. The Koolatron 1.7 cubic foot AC/DC Heat Pipe Fridge use thermoelctric heat pipe technology to cool the contents of the fridge up to 54 F or 30C below the ambient temperature.

The module acts as a heat pump to remove heat away from the fridge. The heat from the thermoeelctric module is absorbed by the heat pipe, vapourizing the liquid refrigerant and rapidly moving heat away from the source, allowing for faster temperature drop. This technology has been widely used by the military, aerospace and computer industries primarily for rapid heat transfer.
