The Anker SOLIX C2000 Gen 2 is our top pick for keeping a fridge and a chest freezer cold through an outage. Its 2,048 Wh battery runs both for about a day, one add-on battery stretches that to about two days, and it usually sells for $700 to $900.
A fridge does not pull much power on average. The compressor runs about a third of the time, so a typical full-size fridge and a 7 cu ft chest freezer together average about 71 W. The hard parts are the start-up spike, up to about 1,000 W for a second, and the way a multi-day outage adds up: roughly 1,700 Wh a day for the pair.
We do not test units ourselves. We picked these from the official spec sheets and manuals, the watt-hour math on this site, and prices we check by hand. Every runtime on this page uses the same formula: battery size times 0.85 for inverter losses, divided by the average draw. See how we pick.

- Battery
- LiFePO4, 4,000 cycles
- Weight
- 41.7 lb
- Wall charge
- 1 h 28 min
- Solar input
- 800 W
Why it won: Its 4,000 W surge rating is far above the 1,080 W or so a fridge needs to start while the freezer is already running. The 2,048 Wh battery keeps a fridge and chest freezer going for about 24 hours, and one BP2000 Gen 2 battery doubles that to about 49 hours. A 10 ms UPS switch-over means the fridge stays on when the grid drops, even if you are asleep or away.
Skip it if: Skip it if you need more than two days without recharging, since it tops out at 4,096 Wh. At 41.7 lb it is also a two-hand carry.
- 2,400 W output with 4,000 W peak handles most kitchen appliances
- Built-in TT-30 outlet plugs straight into an RV
- Expands to 4,096 Wh with one BP2000 Gen 2 battery

- Capacity
- 2,048 Wh
- Output
- 3,000 W (3,600 W surge)
- Battery
- LiFePO4, 4,000 cycles
- Weight
- 48.5 lb
- Wall charge
- 55 min to 80%
- Solar input
- 1,800 W
Why it won: It starts at 2,048 Wh, about 24 hours of fridge and freezer, and expands to 22,528 Wh, enough for roughly 11 days of the pair. Each expansion battery adds 2,048 Wh, so one extra pack gets you to about two days. Solar takes a DJI add-on: up to 1,800 W with the Super Fast Charger, sold separately.
Skip it if: Skip it if you want solar or 12V gear without extra parts. Solar needs a DJI add-on, there is no car socket, and at 48.5 lb with no wheels it is heavy to move. Prices also swing widely, from about $700 to $1,300.
- 3,000 W output covers nearly every household appliance
- Expands to 22,528 Wh with up to ten expansion batteries
- Quiet (30 dB or less) and recharges to 80% in under an hour
- Four USB-C (up to 140 W) and four USB-A ports, plus a 10 ms UPS
- Heavy at 48.5 lb with no wheels
- No 12V car socket; DC output relies on DJI SDC accessories
- Solar and car charging need DJI's add-on chargers

Jackery HomePower 3000
$900–$1,500 · price checked
- Capacity
- 3,072 Wh
- Output
- 3,600 W (7,200 W surge)
- Battery
- LiFePO4, 4,000 cycles (to 70%)
- Weight
- 59.5 lb
- Wall charge
- 2 h 12 min
- Solar input
- 1,000 W
Why it won: Its 3,072 Wh battery runs a fridge and chest freezer for about 37 hours, a day and a half, with nothing to add. With 7,200 W of surge, compressor starts are never a concern, and up to 1,000 W of solar input lets you refill it during a longer outage. For one box that covers an overnight-plus outage, it is the simplest choice.
Skip it if: Skip it if your outages often last two days or more, because it cannot take extra batteries. At 59.5 lb with no wheels, it is also not one to carry up and down stairs, and it usually costs $900 or more.
- 3,600 W output with a 30A outlet can run several appliances at once
- Can feed up to six home circuits through a manual transfer switch
- Takes up to 1,000 W of solar for faster off-grid recharging
- Compact and light for its 3,072 Wh capacity at 59.5 lb
- Cannot add extra batteries; the 2000 Plus or 5000 Plus can
- Still heavy to carry up stairs, with no built-in wheels
- Jackery rates cycle life to 70% capacity, not 80%

- Battery
- LiFePO4, 4,000 cycles
- Weight
- 31.3 lb
- Wall charge
- 56 min
- Solar input
- 1,800 W
Why it won: For usually $450 or less, you get 1,024 Wh and 2,600 W of output, plenty to start a fridge compressor. It runs a fridge and freezer together for about 12 hours, or a fridge alone for about 19. Because it expands to 11,264 Wh, about five and a half days of the pair, you can start small and add batteries later.
Skip it if: Skip it if you want both appliances covered through a full day without buying extra batteries. Solar needs a DJI add-on (400 W with the basic MPPT module), and there is no 12V car socket.
- 2,600 W output from a 1,024 Wh unit
- Full wall recharge in 56 minutes
- Very quiet (about 26 dB) and expands to 11,264 Wh
- 10 ms UPS switch-over for computers and routers
- No built-in 12V car socket; DC needs DJI's SDC accessories
- Solar needs a DJI add-on charger or MPPT module (400 W with the basic module)
- No separate surge rating above the 2,600 W output

Why it won: Two built-in solar inputs take up to 1,000 W total, with no add-on charger needed. The base 1,024 Wh unit covers a fridge and freezer for about 12 hours, and DELTA extra batteries take it to 5,000 Wh, about two and a half days. At the full 1,000 W, under two hours of ideal sun would replace a day of fridge and freezer use.
Skip it if: Skip it if you want a full day of fridge and freezer from the box alone. The base battery is half the size of the C2000 Gen 2, and it usually costs $550 to $800.
- Two solar inputs take up to 1,000 W total (500 W each) for fast off-grid refills
- 140 W USB-C ports charge big laptops at full speed
- 10 ms UPS switch-over suits NAS drives, routers and medical devices
- Full recharge from a wall outlet in 56 minutes
- Same 1,024 Wh capacity as the cheaper DELTA 3
- 27.6 lb and roughly the size of a carry-on bag
- The extra cost over the DELTA 3 buys ports and solar, not capacity

Estimates: battery Wh × 0.85 ÷ the device’s average draw. Real runtime depends on temperature, battery age and how hard the device works.
Your fridge may use more
The fridge column assumes a newer ENERGY STAR model at 150 W while the compressor runs, or about 45 W on average. A 10- to 15-year-old or side-by-side fridge often averages 70 to 90 W. At 80 W, these picks last about 11 hrs on the DJI Power 1000 V2 (1,024 Wh) and about 33 hrs on the Jackery HomePower 3000 (3,072 Wh).
To find yours, divide the kWh per year on the yellow EnergyGuide label by 8.76. That gives the average watts. Fridge runtime on every station

Related comparisons
Torn between two of these? Each comparison gives a verdict, specs and runtimes side by side.
How much battery do a fridge and freezer need?
Start with the average draw, not the label. A full-size fridge runs its 150 W compressor about 30% of the time, which averages about 45 W. A 7 cu ft chest freezer runs about 80 W a third of the time, about 26 W on average. Together that is about 71 W, or roughly 1,700 Wh over 24 hours.
Now add inverter losses. Divide by 0.85 and you need about 2,000 Wh of battery per day for the pair. So a 2,048 Wh station covers about one day, a 3,072 Wh station about a day and a half, and three full days take roughly 6,000 Wh. That last number is why expansion batteries and solar matter so much for long outages.
Most people also keep the internet and a few lights on. A Wi-Fi router and modem at 25 W around the clock use about 600 Wh a day, more than half of what the fridge uses. Add three LED bulbs for five hours each evening and the daily total rises to about 2,450 Wh, or about 2,900 Wh of battery.
Then check surge. The fridge needs up to about 1,000 W for a second when its compressor starts. If the freezer is already running, the station sees about 1,080 W at once. Every pick here clears that easily. A small unit with a 600 W surge limit, like the Jackery Explorer 300 v2, cannot start a full-size fridge at all.
What to look for
Battery chemistry comes first. Every pick here uses LiFePO4 cells rated for 4,000 cycles, so years of storm seasons and test runs will not wear them out quickly. Older NMC packs are lighter for their size but are usually rated for far fewer cycles, which matters for a unit you will drain and refill every time the power goes out.
A UPS switch-over lets you leave the fridge plugged into the station and the station plugged into the wall. When the grid drops, the station takes over in 10 to 20 ms, depending on the model, and the fridge never notices. That matters most at night or when nobody is home to move plugs around.
For outages longer than a day, recharging matters as much as battery size. Solar input ranges from 800 W on the C2000 Gen 2 to 1,000 W on the DELTA 3 Plus and HomePower 3000, and up to 1,800 W on the DJI Power 2000 and Power 1000 V2 with DJI's add-on charger. Expandable units let you buy the base unit now and add batteries later: the DJI Power 2000 reaches 22,528 Wh, the DJI Power 1000 V2 11,264 Wh, the DELTA 3 Plus 5,000 Wh and the C2000 Gen 2 4,096 Wh.
Mistakes to avoid
Buying for battery size and ignoring surge is the most common one. A 300 Wh station could hold a fridge for about 5 hours on paper, but if its surge limit is too low, the compressor never starts and the station just shuts off.
Using a thin extension cord or a power strip between the fridge and the station is another. Long, light cords drop the voltage at start-up and can cause trips. Plug the fridge straight into the station, or use a short, heavy-duty cord.
Finally, do not plan a multi-day outage around one charge. Even the HomePower 3000 runs out after about a day and a half with a fridge and freezer. Decide ahead of time how you will refill it: solar panels, a neighbor's outlet, or an expansion battery you charged before the storm.
Safety
Keep the station dry, on a hard floor and with space around it for airflow. It makes no fumes, so unlike a gas generator it is fine in a kitchen or garage, but do not cover its vents or set it where water can pool during a storm.
Plug appliances straight into the station. Never connect a power station to a wall outlet to feed the house wiring, because that can push power back onto the grid and hurt line workers. If you want the fridge circuit powered through the panel, have a licensed electrician install a transfer switch.
If someone in the house relies on oxygen or other life-support equipment, do not count on the station that runs your fridge. Life-support gear needs its own dedicated backup and a plan from the doctor or equipment supplier.
How can I keep the fridge running longer on one charge?
Turn the fridge a little colder the day before a storm, keep the doors shut and switch off the ice maker. Each door opening lets cold air out and makes the compressor run longer.
Run the freezer in shifts. A full, closed chest freezer stays frozen for a day or more without power, so unplugging it for 12 hours saves about 300 Wh. Moving the router to a USB or DC port, if it can take one, avoids inverter losses too. Between storms, top the station up every few months so it is full when you need it.
Common questions
- How long will a 2,000 Wh power station run a fridge and freezer?
- About 24 hours. A full-size fridge and a 7 cu ft chest freezer together average about 71 W, and a 2,048 Wh station delivers roughly 1,740 Wh after inverter losses. Run the fridge alone and the same station lasts about 39 hours.
- What size power station do I need to run a fridge for 3 days?
- Plan on about 3,800 Wh for a fridge alone and about 6,000 Wh for a fridge plus a chest freezer. The Anker C2000 Gen 2 with one extra battery (4,096 Wh) covers a fridge for three days, and an expanded DJI Power 2000 covers both. Solar input cuts how much battery you need.
- Can a 1,000 Wh power station run a refrigerator?
- Yes, if it has at least about 1,000 W of surge. A 1,024 Wh unit like the DJI Power 1000 V2 runs a typical full-size fridge for about 19 hours, or a fridge and chest freezer together for about 12 hours.
- Will a power station run a chest freezer?
- Yes. A 7 cu ft chest freezer averages about 26 W, so a 1,024 Wh station runs it for about 33 hours and a 2,048 Wh station for about 66 hours. Look for at least 700 W of surge to cover the compressor start.
- Is a power station better than a gas generator for a fridge?
- For outages of a day or two, a power station is quieter, can run indoors and, with a 10 to 20 ms UPS mode, takes over on its own when the grid drops. For week-long outages without sun, a generator can keep going as long as you have fuel. Many people pair a power station with solar panels instead.
