First of all, we need to find out the very important thing: how long can a freezer go without power?

If you are aware of the time period that the foodstuff can stay safe inside the freezing camera, you will then know how much time you have to fix the situation and take appropriate measures.

Also, then it will be clear for how long the freezer power outage can be harmless for its content before everything starts spoiling slowly.

According to the official data derived from the appropriate research, the freezer is able to hold its inside temperature without any significant fluctuations after the power outage for twenty-four hours in case it is half-filled with the content. 

When being full, then the inside temperature will remain stable for two days after the breakdown took place.

Knowing this, you can now be aware of how much time you would have in case of any power outage.

You may be surprised but not any kind of freezer is able to keep the temperature stable for the same period of time.

If we are talking the ordinary freezing camera that any fridge has, then it will last for eighty-four hours in case of a breakdown.

But how long will a chest freezer stay cold without power, for example?

If this kind of freezer happens to have no power, remember that in this case, if it is half-full, you can safely keep food in it for twenty-four hours only which is one day less than in the ordinary freezer.

On the other hand, it the upright freezer it completely filled with the foodstuff, it can remain durable for a period of two to four days at most without any power. 

You can extend its durability period by making a sort of insulation using towels to keep the cold inside.

Only double-check that the compressor remains uncovered.

However, being aware of the period your freezer will stay working is not the only important thing you need to take into account.

The power outage affects the food in the freezer slowly which may cause its spoiling if no measures are taken in time.

Depending on the type of freezer you are using, the average time that the food can spend in it without any harm varies from one to four days.

If the foodstuff is being kept in the ordinary freezing camera that belongs to the fridge, it will remain frozen for two days there.

However, if we are talking an upright freezer, it can keep the groceries frozen for four days in case it is fully filled.

If not, count on the term of twenty-four hours.
