Power outages can be frustrating, especially when it comes to keeping your freezer cold. Whether it’s due to a storm, maintenance work, or any other unforeseen circumstances, losing power can result in spoiled food and expensive losses. However, there are several steps you can take to ensure that your freezer stays cold during a power outage, minimizing the risk of food spoilage and saving you money.
