After you plug in a deep freeze or turn the deep freeze on it can take as long as 4 hours to 10 hours before the deep freezer to get cold enough to freeze foods.
However once you plug in or turn on the deep freezer it takes around 20 to 30 minutes for the deep freezer to begin getting cold.
A freezer should begin getting cold within 20 to 30 minutes of it being plugged in but for the freezer to get really cold and frozen it can take 4 to 10 hours.
A mini fridge should begin getting cold within 20 to 30 minutes of it being plugged in.

When moving a fridge, the compressor oil can leak into the refrigeration system, causing a blockage if the appliance is turned on too quickly.
If the fridge is turned on before the oil has time to drain back, the cylinder shaft can snap when trying to compress the (noncompressible) oil.
If this happened, you would know it immediately, as the compressor would sound different and the fridge would no longer be getting cold.
During a power outage the refrigerator should remain cold enough to keep food for 10 hours to 14 hours as long as the refrigerator door is kept closed.
A freezer should keep froze for up to 24 hours in some cases as long as the freezer door is kept closed.
You can use a generator or solar power to power the refrigerator or freezer long enough to keep it cold.
During a power outage I will plug my refrigerator and freezer into a small generator and run it for an hour or so to allow the food to stay cold.
