Overview
The Whynter UDF-139SS is a large, dual-purpose appliance built around flexibility. At 13.8 cubic feet it delivers serious capacity, and its convertible design lets it run as a deep freezer or as a refrigerator, so the same stainless cabinet can change roles as your storage needs shift.
Digital temperature control is the feature that makes that convertibility practical, letting you dial in precise settings rather than guessing at a dial, and the listing notes Energy Star certification for efficiency at this size. The stainless steel finish matches the look of mid- and full-size kitchen appliances.
At $975.57 and 149 pounds, this is a permanent installation and a real investment, sitting near the top of this lineup on both price and capacity. Its 4.2-star average across 313 ratings reflects a well-reviewed, established model. For a buyer who wants one large, efficient, convertible cold box with digital control, it is a strong high-capacity option.

Performance notes
With 13.8 cubic feet on tap, this holds a household's frozen stock with room to spare, and the convertible design plus digital control mean it can be repurposed as a refrigerator when needed. The Energy Star rating is a meaningful consideration at this capacity, where running costs add up. It is freestanding on a standard 115-volt outlet, but at 149 pounds it should be positioned once and left in place. The stainless exterior lets it sit alongside kitchen appliances rather than being relegated to a basement.
What buyers say
Buyers value the large capacity and the flexibility of switching between freezer and refrigerator modes, and the digital control is frequently cited as making that practical day to day.
