When the power goes out, the refrigerator is usually the first thing people want to save - and it is one of the easiest appliances for a portable power station to run. A fridge does not draw much power on average; it cycles its compressor on and off all day. What matters is how much energy it uses over 24 hours, how hard it kicks at startup, and how big a battery you put behind it.
This guide gives you a runtime chart for real refrigerators, the formula to work out your own, the solar wattage that keeps a fridge running indefinitely, and seven picks from power stations we have in stock and active on October 27, 2026. Prices are store prices before any promo code.
1. Refrigerator runtime by power station
The chart and table assume about 85% of the rated capacity reaches the fridge (inverter losses, battery reserve and the station's own idle draw). Two fridge profiles are shown: a modern ENERGY STAR top- or bottom-freezer model at about 1.2 kWh a day and a large French-door model with an ice maker at about 1.8 kWh a day.
| Power station | Price today | Capacity | Output (surge) | Modern fridge 1.2 kWh/day | French-door 1.8 kWh/day | Max solar in |
|---|---|---|---|---|---|---|
| Jackery Explorer 1000 v2 | $499 | 1,070 Wh | 1,500 W (3,000 W) | ~18 h | ~12 h | 400 W |
| Anker SOLIX C1000 Gen 2 | $499.99 | 1,024 Wh | 2,000 W (3,000 W) | ~17 h | ~12 h | 600 W |
| Anker SOLIX S2000 | $699.99 | 2,010 Wh | 1,500 W (3,000 W) | ~34 h | ~23 h | 400 W |
| Jackery Explorer 2000 v2 | $899 | 2,042 Wh | 2,200 W (4,400 W) | ~35 h | ~23 h | 400 W |
| Anker SOLIX C2000 Gen 2 | $899.99 | 2,048 Wh (4,096 Wh with BP2000) | 2,400 W (4,000 W) | ~35 h (~70 h) | ~23 h (~46 h) | 800 W |
| Bluetti Elite 200 V2 | $899 | 2,074 Wh | 2,600 W (3,900 W lifting mode*) | ~35 h | ~24 h | 1,000 W |
| Anker SOLIX F3000 | $1,399.99 | 3,072 Wh | 3,600 W (7,200 W) | ~52 h | ~35 h | 2,400 W |
| Jackery HomePower 3600 Plus | $1,709 | 3,584 Wh | 3,600 W (7,200 W) | ~61 h | ~41 h | 1,000 W |
| Jackery Explorer 5000 Plus | $3,149 | 5,040 Wh | 7,200 W (14,400 W) | ~86 h | ~57 h | 4,000 W |
*Bluetti lists a 3,900 W "Power Lifting" mode for resistive loads rather than a motor surge figure; its 2,600 W continuous rating is still far above what a fridge compressor needs to start. Specs are from the manufacturer data on each product page.
How do our numbers compare with the brands' own tests? Anker rates the S2000 at up to 35 hours on a 700 L refrigerator in its lab (77°F room) and the C2000 Gen 2 at 15-32 hours for a 190 W fridge; our 34-35 hour estimate for a 1.2 kWh-a-day fridge lands in the same place. Jackery's listings use a more cautious 150 W continuous load, which is why they show only about 6 hours for the Explorer 1000 v2 - a fridge that never stops its compressor. Most fridges in a 70°F kitchen run 30-50% of the time.
2. The runtime formula (work out your own fridge)
Runtime (hours) = power station Wh x 0.85 / average fridge watts, where average watts = kWh per day x 1,000 / 24.
- Find daily kWh. The yellow EnergyGuide label on the fridge (or the model's spec sheet) shows kWh per year. Divide by 365. A label reading 438 kWh/year is 1.2 kWh a day.
- Convert to average watts. 1.2 kWh x 1,000 / 24 = 50 W.
- Apply the formula. For a 2,010 Wh station: 2,010 x 0.85 / 50 = about 34 hours.
Want a direct reading instead? A plug-in watt meter between the fridge and the wall for 24 hours gives the real number for your kitchen. Many power stations also show live input and output watts on the screen or app, so you can watch the fridge cycle once you plug it in.
Typical refrigerator energy use
- Compact or dorm fridge: about 0.6-0.9 kWh a day (25-40 W average).
- Chest freezer, 5-7 cu ft: about 0.6-0.8 kWh a day - chest freezers are efficient because cold air stays in when the lid opens.
- Modern top- or bottom-freezer fridge, 18-21 cu ft: about 1.0-1.4 kWh a day.
- French-door or side-by-side with ice maker and dispenser: about 1.6-2.2 kWh a day.
- Older fridge (15+ years) or a second fridge in a hot garage: 2-3 kWh a day or more.
What shortens runtime
- Heat. A fridge in a 90°F garage runs far longer than one in a 68°F kitchen.
- Door openings and warm food. Each opening dumps cold air; a load of warm groceries makes the compressor run for an hour.
- Defrost cycles and ice makers. Frost-free fridges run a defrost heater of several hundred watts for a short period every day or so, and ice makers add heaters too. Turn the ice maker off during an outage.
- Station idle draw. The inverter itself uses power whenever AC output is on. Anker lists 6 W idle for the S2000 and 9 W for the C2000 Gen 2; over a day, 10 W of idle is 240 Wh - a fifth of what the fridge uses. Turn off USB ports and screens you do not need.
- Cold rooms. LiFePO4 batteries deliver less below freezing; keep the station in the heated part of the house.
3. Starting surge: why output watts still matter
A conventional compressor fridge runs at roughly 100-250 W, but for a fraction of a second at startup it can pull several times that - often 600-1,200 W on older units. Every station in the table handles this: the smallest is rated 1,500 W continuous and 3,000 W surge. Newer "inverter" or variable-speed compressors start softly and are even easier to run.
Surge becomes a factor when the fridge shares the station with other loads. A microwave (1,000-1,500 W) plus a fridge starting at the same moment can trip a 1,500 W unit like the S2000 or Explorer 1000 v2. If you plan to run the fridge, a microwave and a coffee maker from one station, choose 2,200 W or more - the Explorer 2000 v2 (4,400 W surge), C2000 Gen 2 or the 3,600 W F3000. Our solar generator sizing guide has the full running-vs-starting watts checklist.
4. Solar: keeping a fridge running for days
Battery capacity buys hours; solar panels buy days. To run a fridge indefinitely, the panels must replace its daily use: solar watts = daily kWh x 1,000 / (sun hours x 0.75). At 4 sun hours that means:
- Modern fridge, 1.2 kWh a day: about 400 W of panels - for example two 200 W panels such as the SolarSaga 200W or Anker PS200.
- French-door fridge, 1.8 kWh a day: about 600 W.
- Fridge plus chest freezer, about 1.9 kWh a day: about 650 W.
Check that the station's solar input accepts that wattage. The Explorer 1000 v2 and S2000 top out at 400 W, enough for one modern fridge on a good day. The C2000 Gen 2 (800 W), HomePower 3600 Plus and Elite 200 V2 (1,000 W) and F3000 (2,400 W) leave room for a fridge, freezer and some extra loads. In winter or under cloud, plan on half the summer output and lean on battery capacity.
5. Our picks for running a refrigerator
Anker SOLIX S2000 - 2,010 Wh, 1,500 W - $699.99
The S2000 is built around exactly this job. Its 2,010 Wh of LiFePO4 (314Ah cells rated for 6,000 cycles to 80%) carries a modern fridge for about a day and a half, and Anker's own lab test shows up to 35 hours on a 700 L refrigerator. The very low 6 W idle draw and 88% efficiency at 100 W matter here, because a fridge spends most of the day at light load. It has a 10 ms UPS function, so you can leave the fridge plugged in through the station and it switches over automatically when the grid fails. At 35.7 lb and 8.2 x 11.1 x 12.7 in, it fits beside the fridge.
Anker SOLIX C2000 Gen 2 - 2,048 Wh, 2,400 W - $899.99
For a fridge plus a chest freezer, or a fridge with a microwave and coffee maker in the mix, the C2000 Gen 2 adds output and growth. It delivers 2,400 W (4,000 W peak), idles at 9 W and accepts 800 W of solar - enough to keep a fridge and a freezer going on a sunny day. Add one BP2000 Gen 2 battery and you have 4,096 Wh; Anker quotes up to 64 hours for a dual-door fridge in that configuration. The C2000 Gen 2 + BP2000 bundle is $1,598.99, and the solar generator with a PS200 panel is $1,169.99.
Jackery Explorer 1000 v2 - 1,070 Wh, 1,500 W - $499
If your outages are usually overnight, the Explorer 1000 v2 covers about 18 hours of a modern fridge for under $500. Three pure sine wave outlets give 1,500 W continuous and 3,000 W surge, the emergency charge mode refills it in about an hour from the wall, and it takes up to 400 W of solar. The Solar Generator 1000 v2 with a SolarSaga 200W panel ($789) adds enough sun to stretch a small fridge or a dorm fridge into multiple days. Warranty is listed as 3+2 years.
Anker SOLIX C1000 Gen 2 - 1,024 Wh, 2,000 W - $499.99
The C1000 Gen 2 recharges from 0 to 100% in 49 minutes from a wall outlet, which suits rolling or intermittent outages: top it up whenever power returns and keep the fridge running through the next gap. It also has more output than the Explorer 1000 v2 (2,000 W, 3,000 W peak) and takes 600 W of solar. Anker lists 7-14 hours for a double-door refrigerator, in line with our 12-17 hour estimate.
Jackery HomePower 3600 Plus - 3,584 Wh, 3,600 W - $1,709
For storms that knock power out for two or three days, the HomePower 3600 Plus runs a modern fridge for about 2.5 days on battery alone - or a fridge and a chest freezer for about 1.5 days - with 3,600 W (7,200 W surge) left for a microwave, sump pump or space heater. It accepts 1,000 W of solar, has a TT-30 30A outlet, uses 6,000-cycle LiFePO4, and expands to about 21 kWh with battery packs. Paired with a manual transfer switch it powers the kitchen circuits directly.
Jackery Explorer 5000 Plus - 5,040 Wh, 7,200 W - $3,149
When the fridge is one of many loads - two refrigerators, a freezer, a well pump or 240V appliances - the Explorer 5000 Plus is the step up. It stores 5,040 Wh (about 3.5 days of a modern fridge on its own), outputs 7,200 W with 14,400 W surge, accepts up to 4,000 W of solar and expands to 60 kWh with battery packs. With Jackery's 60A Smart Transfer Switch it backs up 12 circuits at 120V or 6 at 240V. See our solar generators for home backup guide for how it compares with larger systems.
Anker SOLIX EverFrost 2 40L - built-in 288 Wh battery - $699.99
For a campsite, boat or road trip, a battery-powered compressor cooler is more efficient than running a home fridge from a power station. The EverFrost 2 40L (42 qt) holds -4°F to 68°F, chills from 77°F to 32°F in 15 minutes, and runs about 52 hours on its removable 288 Wh LiFePO4 battery (about 104 hours with a second battery). It recharges from a 100 W solar panel, a car socket, a wall outlet or USB-C.

7. What our customers ask
Fridge backup questions reach us by phone, text and email in a few repeating patterns (shared here without any personal details):
- "Is this the right price?" Buyers often text a link to a 2 kWh station to confirm the price before ordering. We confirm on the spot and send the ecosolarkits.com link.
- "Will these panels work with my station?" Panel-to-station compatibility is the most common pre-sale question: connector type, voltage window and the station's maximum solar watts. Section 4 lists the solar input for each pick.
- "How big do I need?" We send the Solar Kit Calculator first, then check the result against the fridge's EnergyGuide label and anything else the customer wants to run.

9. FAQ
How long will a power station run a refrigerator?
Divide the station's watt-hours by the fridge's average watts, after about 15% losses. A modern ENERGY STAR refrigerator using about 1.2 kWh a day averages 50 W, so a 1,000 Wh station runs it for roughly 17-18 hours, a 2,000 Wh station for about 34-35 hours and a 3,600 Wh station for about 2.5 days. A large French-door fridge with an ice maker (about 1.8 kWh a day) cuts those times by a third.
What size power station do I need to run a refrigerator?
For one modern fridge, choose at least 1,000 Wh for an overnight outage and about 2,000 Wh to cover a full day with margin. The inverter should be rated 1,500 W or more with a surge rating of 3,000 W, which covers the startup draw of almost any household refrigerator. For a fridge plus a chest freezer, or outages longer than a day, look at 3,000-5,000 Wh or add solar panels.
Can a 1000W power station run a refrigerator?
Yes. A running refrigerator usually draws 100-250 W while the compressor runs and briefly several times that at startup, well within a station rated 1,000-2,000 W continuous with 3,000 W surge. The limit is battery capacity, not output: a 1,000 Wh unit keeps a modern fridge going for about 17-18 hours.
How many watts does a refrigerator use?
A typical full-size refrigerator draws about 100-250 W while the compressor runs, but it cycles on and off, so its average is only about 30-110 W. That works out to roughly 0.8-2.5 kWh a day depending on size, age and features. Check the yellow EnergyGuide label: divide the kWh per year by 365 to get your daily figure.
How many solar panels does it take to run a refrigerator?
Divide the fridge's daily kWh by about 3 kWh per kW of panels (4 sun hours x 75% real-world losses). A modern 1.2 kWh-a-day fridge needs about 400 W of panels, a French-door model about 600 W and a fridge plus freezer about 650 W. The power station's solar input must accept that wattage.
Is it safe to run a refrigerator from a portable power station indoors?
Yes. Battery power stations produce no exhaust, so unlike a gas generator they can sit in the kitchen. Plug the fridge directly into the station's AC outlet with no thin extension cord, keep the vents clear, and do not connect the station to a wall outlet to feed the house - use a transfer switch installed by a licensed electrician for that.
How long does food stay safe in a fridge without power?
According to USDA guidance, a refrigerator keeps food safe for about 4 hours if the door stays closed, a full freezer about 48 hours and a half-full freezer about 24 hours. Perishables that sit above 40°F for more than 2 hours should be discarded. A power station extends those windows from hours to days.
