Best Portable Power Station for Refrigerator (2026) — Runtime Calculator Inside
When the power goes out, your first worry is the fridge. The FDA says food is safe for about 4 hours in a closed refrigerator without power. After that, you’re looking at hundreds of dollars in spoiled groceries. A portable power station solves this — but you need enough capacity and output to actually keep a fridge running.
The key number: most full-size refrigerators draw 100-200W while running, but compressors cycle on and off. Average consumption is typically 1-2 kWh per day. That means a 1000Wh power station can keep your fridge running for roughly 10-20 hours depending on the model, ambient temperature, and how often you open the door.

Refrigerator Power Math
Before picking a power station, understand what your fridge actually consumes:
Typical refrigerator power draw:
- Running wattage: 100-200W (while compressor is on)
- Startup surge: 800-1200W (compressor kick-on, lasts 1-2 seconds)
- Average daily consumption: 1-2 kWh (because the compressor cycles on/off)
- Real-world average hourly draw: 60-80W when accounting for cycling
Runtime formula: Runtime (hours) = Power Station Capacity (Wh) × 0.85 (inverter efficiency) ÷ Average Fridge Draw (W)
Example: 1056Wh × 0.85 ÷ 70W average = ~12.8 hours
Important: Every fridge is different. Check the yellow EnergyGuide sticker on your refrigerator for annual kWh consumption. Divide by 365 to get daily consumption, then divide by 24 for average hourly draw.
1. Anker Solix C1000 Gen 2 — Best Overall for Fridge Backup
Why it leads: The C1000 Gen 2 offers enough capacity for a full day of fridge operation, charges fast enough to top up during brief power restorations, and costs significantly less than higher-capacity alternatives.
Estimated fridge runtime: 10-18 hours (varies by fridge model and ambient temperature)
Why it works for fridges:
- 2000W output handles any residential refrigerator’s compressor startup surge (typically 800-1200W) with plenty of headroom
- 49-minute recharge means if power comes back briefly, you can fully recharge before the next outage
- 1056Wh capacity covers most outages — the average US power outage lasts 7 hours
- Can simultaneously power the fridge plus charge phones and run LED lighting
Standout features:
- The fast charging is especially valuable for fridge backup. During rolling blackouts or intermittent outages, you can fully recharge during the “on” periods and run the fridge during “off” periods indefinitely.
- At 25 lbs, you can move it between the kitchen (near the fridge) and other rooms as needed.
Worth considering:
- For outages longer than 18 hours, you’ll need to recharge or step up to a higher-capacity unit.
- Pair with a 200W solar panel ($200-300) for indefinite runtime during daylight hours.
Verdict: Best balance of price, capacity, and charging speed for typical power outages. Handles most situations without overspending.
2. Bluetti AC200L — Longest Runtime
Why it’s here: 2048Wh keeps a fridge running for 20-36 hours without recharging. For extended outages from storms, hurricanes, or grid failures, this extra capacity means not worrying about food spoilage.
Estimated fridge runtime: 20-36 hours
Why it works for fridges:
- 2048Wh capacity provides genuine multi-day backup with conservative fridge usage
- 2400W output runs a fridge plus multiple other appliances simultaneously
- Expandable to 8192Wh with additional batteries for multi-day backup
- 1200W solar input can fully recharge from solar panels in under 2 hours
Standout features:
- The expansion capability is the real selling point. With two B300 batteries ($900 each), you get 8192Wh — enough to run a fridge for 4+ days continuously.
- 30A RV outlet makes this versatile for both home and RV refrigerators.
Worth considering:
- 62 lbs makes it immobile once placed. Plan where it goes in advance.
- $1,099 is a significant investment for fridge backup alone. Only justified if you experience regular extended outages.
Verdict: Best for hurricane country, rural areas with unreliable grid, or anyone who wants maximum peace of mind during extended outages.
3. EcoFlow Delta 3 Plus — Best Expandable
Why it’s here: Similar base capacity to the Anker, but the ability to add batteries later means you can start with 1024Wh and scale up to 5kWh as needed.
Estimated fridge runtime: 10-17 hours (base), expandable to 50+ hours
Why it works for fridges:
- 10ms UPS switchover means the fridge never actually loses power during an outage — the transition is seamless
- Start with the base unit and add capacity later if needed
- 2400W handles any fridge plus other appliances simultaneously
Standout features:
- The UPS functionality is uniquely valuable for refrigerators. Plug the fridge into the Delta 3 Plus, keep it plugged into the wall, and it automatically switches to battery during an outage without the compressor ever stopping.
- Expandable design means you’re not locked into a capacity decision upfront.
Worth considering:
- Base capacity (1024Wh) provides similar runtime to the cheaper Anker C1000 Gen 2.
- Expansion batteries ($400-700 each) add up quickly.
Verdict: Best “grow into it” option. Start with the base unit, add batteries if your outage situation demands it.
4. Jackery Explorer 2000 V2 — Best Value per Runtime Hour
Why it’s here: At $799 for 2042Wh, the Explorer 2000 V2 offers the lowest cost per Wh in this roundup — meaning the cheapest extended fridge runtime.
Estimated fridge runtime: 19-34 hours
Why it works for fridges:
- 2042Wh at $799 = $0.39 per Wh — best value for raw capacity
- 2200W output easily handles any residential fridge
- 1.5-hour charge time from a wall outlet
Standout features:
- Best cost-per-hour of fridge runtime in this comparison. For pure fridge backup on a budget, this is the math winner.
- Jackery’s simple interface means anyone in the household can operate it during an emergency.
Worth considering:
- 39 lbs is heavy. Designate a permanent spot near your fridge.
- Not expandable — what you buy is what you get.
Verdict: Best value if your primary goal is running a fridge for extended periods and you want to spend as little as possible per hour of runtime.
5. EcoFlow Delta Pro 3 — Multi-Day Fridge Backup
Why it’s here: When outages last days (hurricanes, ice storms, grid failures), the Delta Pro 3’s 4096Wh base capacity and 48kWh expansion potential means your fridge runs indefinitely.
Estimated fridge runtime: 40-68 hours (base), expandable to 400+ hours
Why it works for fridges:
- 4096Wh base capacity runs most fridges for 2-3 days without recharging
- 120V/240V output can power even commercial refrigerators and deep freezers
- Integrates with EcoFlow Smart Home Panel for automatic whole-home switchover
- Can charge from EV charging stations — find a working one and fully recharge
Standout features:
- This is the only option here that can run both a fridge AND a deep freezer simultaneously for multiple days.
- With the Smart Home Panel, your entire kitchen circuit switches over automatically.
Worth considering:
- $2,699 is a major investment. Only makes sense for areas with frequent multi-day outages.
- 114 lbs requires a permanent installation location.
Verdict: The nuclear option for fridge backup. If you’ve lost hundreds in spoiled food from past outages, this pays for itself over time.
Tips to Maximize Fridge Runtime
- Keep the door closed. Every door opening lets cold air escape and adds 10-15 minutes of compressor runtime. Organize what you need and grab everything at once.
- Lower the thermostat in advance when you know a storm is coming. A colder starting temperature means longer safe time.
- Fill empty space with water bottles. Frozen water bottles act as thermal mass, keeping the fridge cold longer even when the compressor is off.
- Move the power station close to the fridge to minimize extension cord losses.
- Pair with solar panels for indefinite runtime during daylight hours. A 200W panel ($200-300) can offset most fridge consumption during the day.
FAQ
Can a portable power station run a full-size refrigerator? Yes. Any power station with 1000W+ output handles the compressor startup surge, and 500Wh+ capacity provides several hours of runtime. The models recommended here all handle standard residential refrigerators easily.
How long will a 1000Wh power station run my fridge? Approximately 10-18 hours, depending on your fridge’s efficiency, ambient temperature, and how often you open the door. Modern Energy Star refrigerators will run longer than older models.
Do I need to worry about the fridge compressor surge? The compressor startup surge (800-1200W for most residential fridges) is well within the output rating of all power stations recommended here. This is only a concern with very small power stations under 500W output.
