How much power do Deep Freezers actually use?Given the state of the world, you could be forgiven for planning ahead with things like back-up power and a method of preserving food.

Deep freezers – or chest freezers – are great for storing large amounts of food for a long time.

But how much juice do they really use?

If you’re running on the back-up power of a generator, for example, will the deep freezer suck too much electricity?

It turns out the answer will surprise you!

Off we go:

Also, note that some chest freezers use less instantaneous power. I have one that only uses a max of 120W! However, it’s annual kilowatt-hour rating is the same as other units that use 200W. So, a lower power rating doesn’t necessarily mean a lower annual operating cost. Sometimes, the compressor just runs more to compensate.

Finally, keep in mind that the bigger the deep freezer and the more frozen food you have inside, the longer it will all last in the event that you have to unplug it. It’s the same as a small ice cube vs a block of ice the size of a car: the big block of ice will last WAAAY longer.

    Hi there Scottie: today’s wisdom words were not what I expected but I enjoyed them just the same..and it was an excellent reminder..and I could kick myself for giving away my upright freezer to a family, that needed it much more than I..this winter has been so cold that much that I freeze to eat over the next 4 months are in portable non electric coolers are are rock hard…the smaller items I keep in the fridge freezer that is at the bottom…we have a generator in case of a power outage.failing that I have Nature’s sub sub zeros…great distraction..your the best..Joan
