Best Generator for Inside Apartments Refrigerator Backup

A sudden power outage is not just an inconvenience, it is also a threat to expensive refrigerated and frozen food. If you live in an apartment, the solution is not a loud, smelly gas generator. You need a safe, quiet, and reliable generator for inside apartments refrigerator backup.

While most people use the term “Generator,” the ideal solution for indoor use, especially in an apartment, is almost always a Portable Power Station (which uses a large battery, not gasoline or fuel based). The only exception for a true gas-powered inverter generator is if you can run it outside on a balcony or patio, far from windows and vents, due to deadly carbon monoxide (CO) fumes.

However, in this guide: I will focus on the best indoor and outdoor-safe generator options to keep your essentials running when the grid goes down.

Understanding Refrigerator Power Needs

Before choosing a backup power source, you need to understand how much power your refrigerator requires:

• Running Watts: This is the continuous power needed to keep the unit operating. A modern refrigerator typically requires 100-250 Watts.
• Surge/Starting Watts (Crucial): This is a brief, high burst of power needed when the compressor first kicks on. This surge can be 500 to 1,500 Watts or more.

Your backup power source must be capable of handling the high surge wattage, even if it only lasts for a second. Fortunately, the high-end power stations we review below are perfectly suited for this task.
