Best Power Station for Overlanding Fridges (2025)

Keep your overlanding fridge running off-grid. Tested power stations for 12V fridges, dual-zone coolers, and extended trips.

Quick Answer

A typical overlanding fridge draws 40-60 watts while cooling, but cycles on and off—averaging 30-45 watts over time. For a weekend trip, you need 500-800Wh. For a week off-grid, get 1000Wh+ or add solar.

Top Picks for Overlanding Fridges

Best Overall: EcoFlow Delta 2 — $399

The Delta 2 is the overlanding standard. Enough capacity for a weekend, expandable for longer trips, and fast charging when you get back to civilization.

Why it works for overlanding:

• 1024Wh runs a 12V fridge for 2-3 days
• 1800W output powers fridge + other gear simultaneously
• Expandable to 3kWh with extra battery
• 500W solar input for off-grid recharging
• Charges to 80% in 50 minutes at camp or home

Real-world runtime: 45W average fridge = ~22 hours continuous, 2-3 days with cycling

Overlanding Fridge Power Math

Step 1: Find your fridge’s power consumption

• Check the specs on your fridge (rated watts vs average)
• Most 12V overlanding fridges: 40-60W while running
• They cycle on/off, averaging 30-45W over time
• Dual-zone fridges use more (50-70W average)

Step 2: Factor in ambient temperature

• Hot weather = fridge runs more often
• 90°F+ days can increase consumption by 30-50%
• Shade your fridge to reduce power draw

Step 3: Calculate your needs

12V vs AC: Which Output to Use?

Use the 12V DC output when possible.

• More efficient (no AC conversion loss)
• Runs cooler
• Many overlanding fridges are 12V native

Use AC output when:

• Your fridge only has an AC plug
• Running multiple devices simultaneously
• Fridge has AC-only features

Efficiency difference: 12V DC is roughly 10-15% more efficient than running through the AC inverter.

Solar Integration for Indefinite Runtime

Pair your power station with solar panels for trips longer than a few days:

The math: A 45W average fridge uses ~1080Wh per day. A 200W panel on a sunny day generates ~800-1000Wh. That’s close to break-even, with your power station covering cloudy days and overnight.

Recommended setup for week+ trips:

• 1000Wh+ power station
• 200W portable solar panel
• Result: Indefinite fridge runtime in sunny conditions

Popular Overlanding Fridges and Power Needs

Mounting and Setup Tips

Secure your power station. Overlanding involves rough roads. Strap it down or use a mounting system.

Ventilate. Power stations generate heat under load. Don’t stuff them in enclosed spaces.

Protect from dust. Cover ports when not in use. Desert dust kills electronics.

Pre-cool your fridge. Plug in the night before at home. Cold fridges use less power to maintain temperature.

Use a fridge thermometer. 37°F is cold enough for food safety. Colder wastes power.

Bottom Line

For trips longer than a week, add a 200W solar panel to any of these. You’ll have indefinite fridge runtime in sunny conditions.
