A chest or upright freezer is another 24/7 box. Chest freezers are often cheaper to run for the same interior volume because cold air does not fall out as fast when you open the lid. An upright feels like a fridge and can cycle more after door time.
A garage freezer in a hot climate works harder in summer. A full freezer holds temperature better than a near-empty one. Manual-defrost frost buildup acts like insulation in the wrong place and stretches runtime.
This is not the freezer drawer inside a kitchen refrigerator. That draw is already in the fridge card.
Whatt treats it as always-on. Set size and a typical average wattage, or Fine-tune from a label.
At 18.8¢ per kWh, a freezer that averages 40 watts over the day uses about 1.0 kWh — roughly 0.19 a day, about 5.60 in 30 days. A struggling garage unit that averages 80 watts is about twice that usage line.
Where it sits
A garage in July is a harder climate than a basement. If the unit ices over, runtime stretches. That is this card, not the kitchen refrigerator.
