How to choose
Check the ENERGY STAR certification
An ENERGY STAR certification marks a model that meets a set efficiency standard, so it is a useful first filter for this search. The Upstreman and the Whynter both carry that certification. The BODACIOUS states low energy consumption of 156.95 kWh per year instead. Compare those stated figures side by side rather than judging efficiency from size alone.
Match capacity to your storage
Capacity decides how much frozen food a unit can hold, and the three picks cover very different amounts. The Upstreman holds 21.2 cu ft, the BODACIOUS holds 3.2 cu ft, and the Whynter holds 2.1 cu ft. Measure what you store in a typical week, then pick the capacity that still holds it with room for bulky items.
Compare controls and defrost
A touch panel sets temperatures with electronic controls. The Upstreman has a touch panel and frost-free operation, the Whynter has a mechanical temperature control, and the BODACIOUS has a manual defrost design. Frost-free operation avoids manual defrosting, while a manual defrost model needs periodic defrosting as upkeep.
