From what I've read (which was when I was seeing how feasible it is to run a fridge-freezer on a battery backup (Ecoflow, Jackery, Bluetti, etc), freezers (or at least fridge-freezers) don't continuously draw even 250W. Most of the time they draw a very small current. But when the compressor kicks in that current spikes right up.

On that topic of running one off a battery backup, the conclusion I came to is that it's feasible as long as the battery has enough capacity to handle those spikes. So like a 1000W battery should be fine. But the battery will still drain quicker than you might think. Using a smaller chest freezer (preferably one that can be converted to/from a freezer and a fridge) is more efficient and will be more bang for your MWh.
