The improved Unique 8 has something that consumers have been asking for years a much larger freezer. This model has increased the freezer size from 1.1 cu/ft to 1.7 cu/ft, the largest in its class! More comfort for the weekend, and ice for your drink. The new Unique 8 is also quite a bit taller than our old version (not as deep), making it easier to access food and drink. All our Unique 8 versions come with dual power (LP gas/110 volt backup).
