What Size Power Station Do I Need to Run a Fridge?

There’s nothing worse than soggy sausages or warm beers halfway through your trip. If you want to keep your camping fridge humming, you’ll need the right-sized portable power station. It’s not just about watts and volts—it’s about choosing a reliable power station to run a refrigerator without draining your whole setup. So, can you run a fridge off a power station? Absolutely—with the right specs.

Can You Run a Fridge Off a Portable Power Station?

Yes—but always factor in both the continuous and surge requirements. The best portable power station for refrigerator use is one that can meet both without breaking a sweat.

Understanding Your Fridge's Power Consumption

Checking the Manufacturer's Specifications

Most fridges list power consumption in watts (W). This is a good starting point to know how much energy your fridge will use.

Estimating Based on Fridge Size

If you don't have specific wattage data, use a rough estimate based on fridge type: Mini fridge (50–100W), Compact fridge (100–200W), and Standard camping fridge (200–300W).

Battery Capacity, Runtime & Power Station to Run Refrigerator

Understanding Battery Capacity

Portable power stations list their capacity in watt-hours (Wh). More Wh = more runtime, but also larger size and weight.

Calculating Runtime

Use this formula: Battery capacity (Wh) ÷ Fridge power (W) = Hours of runtime. For example, a 100W fridge running on a 600Wh power station would last around 6 hours.

Recharge Options & Fridge Efficiency

Choose power stations that offer solar, vehicle, or wall outlet charging options for added flexibility, especially during long trips. Compressor fridges are more efficient than absorption types, so factor this into your choice for longer trips or multi-day use.

Tips for Using a Portable Power Station to Run a Refrigerator

Fridge Maintenance and Energy Conservation Tips

Minimise Door Openings

Open the fridge only when necessary to reduce compressor cycles and save power.

Keep It Level

Ensure that the fridge is level for better cooling, especially for absorption fridges that require proper orientation.

Don’t Overfill

Overpacking blocks airflow, which can make the fridge work harder and consume more energy.

What Size Portable Power Station Will Run a Refrigerator?

For overnight use, a power station with 300–500Wh is usually sufficient. For longer durations, aim for a 1000Wh+ unit, preferably with solar recharge capabilities.
