Learn how to keep your fridge cold without power using effective tips like utilizing ice, keeping the fridge closed, blocking openings, using insulation, and using a power bank. These tips will help preserve your food and keep your fridge cool during a power outage.


A power outage can be a common problem during extreme weather and can significantly affect household appliances like fridges. Keeping your fridge’s temperature normal is crucial, especially in preserving food. In this article, we will provide you with effective tips on how to keep your fridge cold without power.

Utilize Ice

Ice is a great tool in keeping the fridge temperature down. The presence of ice allows the fridge to absorb the heat and maintain a cool environment.

To use ice, you can fill Ziploc bags with ice cubes and place them strategically in the fridge. Be sure to place them in a way that leaves space between the bags and the fridge walls for cool air to circulate. This technique will help your fridge stay cold for up to 48 hours.

Keep the Fridge Closed

An opened fridge immediately disrupts the temperature inside, causing it to rise. The more often the fridge is opened, the faster the temperature increases.

One of the simplest ways to reduce the need to open the fridge constantly is to plan and prepare meals beforehand. Doing so minimizes the need to search for food, reducing the chances of leaving the fridge door open for too long.

Block all Openings

Opening is not the only factor that affects the fridge’s temperature. Any opening, no matter how small, can let cold air out. This can include the space between the fridge’s door and the frame or even a faulty seal.

One effective method is to block all openings using materials like duct tape, rolled towels, or even magnetic strips. Doing so will prevent hot air from entering, and cool air from escaping, keeping your fridge cold.

Use Insulation

Insulation helps prevent heat from entering and cool air from escaping, thereby maintaining a consistent temperature inside the fridge. It is a useful method to keep the fridge cool, especially when there is no power.

You can use any insulating material like blankets, towels, or even bubble wrap to wrap around your fridge. Do not forget to leave adequate ventilation space between the fridge and the insulation material.

Use a Power Bank

Another way to keep your fridge cool when the power is out is by using a power bank. This method, however, requires a power bank with a battery strong enough to power the fridge.

To select the right power bank, consider the size of your fridge and check its power consumption rate. Then select a power bank with a battery strong enough to power the fridge for an extended period.


Keeping your fridge cold during a power outage is crucial to preserving your food and maintaining a healthy lifestyle. We have provided several effective tips to keep your fridge cold without power. Be sure to plan and prepare for power outages and utilize these tips to preserve your food and keep your fridge cool.
