How to Choose the Right Power Station for Your Refrigerator

Understanding Your Fridge's Power Needs (Watts & Watt-hours)

Check your fridge’s manual or label for its wattage.
Most household fridges use 100–200W when running, but starting watts can be much higher.
Multiply watts by hours to calculate your needed Wh.

Key Features to Look For (UPS, Battery Type, and Ports)

Important considerations include:

• Battery type (Li-ion or LiFePO4 for long life and efficiency)
• Port variety (AC, DC, USB)
• UPS capability for seamless power switchover

Sizing a Power Station for Different Refrigerator Types

• Mini fridge: Minimum of ~300–500Wh capacity
• Full-size fridge: 1,500Wh+ for several hours of runtime
• Off-grid/long outages: Expandable systems such as the DELTA Pro

Running a Fridge During a Power Outage

The runtime of a fridge on a portable power station depends on both the fridge’s wattage and the station’s battery capacity. For example, a 100W fridge paired with a 1,000Wh power station could operate for about 8–9 hours once efficiency losses are considered.

Portable Power Stations vs. Gas Generators for Home Backup

For keeping fridges and small appliances running, portable power stations are a practical replacement for gas generators. However, for whole-home backup, only larger or expandable models—such as the DELTA Pro—can offer comparable performance.
