A possible way to keep your fridge cold in long term blackouts.

So where I live I have never seen a blackout in 17 years last longer than 2 hours. We are getting a lot of bad storms and I was just even considering the problem.

Originally I thought what may be actually the most 'efficient', like in terms of input to output power, would be to modify a fridge compressor so it could be fed from a belt. The belt would connect to some sort of rotating power source, like a bike, or windmill.

Then I was thinking the most normal and easy way to do it is to get a power bank of some sort with a 120V inverter.

In this video it seems to do most of the things you need.


So I have the following sort of questions.

1) Provided a fridge is not all the time, but is on some of the time, can you humanly input the same power as a fridge uses (different if not started warm)?
2) With 120V inverters are there power losses when appliances are idle or disconnected?

So in conclusion based on the fact it does not happen here and I don't have a lot of value in terms of loss in my fridge, I think I am just going to ignore the problem.

I have come to the same conclusion.

No
Typical residential fridge+freezer, 300-400kWh per year:

Most humans are unable to produce 100W continuously:

1kWh/day at least 10 hours continuous human effort

Please demonstrate this! You won't be able to.
