One appliance at a time from a full charge. Run time = 2.05 kWh x 85% usable (1,741Wh) divided by the appliance's watts, the same formula our outage calculatoruses. "Start not confirmed" means the running watts fit but EWEB's worst-case starting watts are above the surge the station can give a motor. Watts are typical figures from the sources below; your appliance's label is the better number.

What the Anker SOLIX C2000 Gen 2 cannot run

  • 12,000 BTU window AC (3,250 W). Needs 3,250 W running; the Anker SOLIX C2000 Gen 2 gives 2,400 W.
  • An electric water heater. About 4,500 W (EWEB), more than twice what the Anker SOLIX C2000 Gen 2 puts out. Nor anything that needs 240 V: the Anker SOLIX C2000 Gen 2 has 120 V outlets only.
  • Several big loads at once. Add up the running watts of everything switched on: it must stay under 2,400 W. A space heater (1,500 W) plus a microwave (1,000 W) is already over.

How it compares

  • About the same size: the Bluetti Elite 200 V2 ($899, checked November 6, 2026) has 2.07 kWh: a fridge about 18 hours. It has 2,600 W of output to the Anker SOLIX C2000 Gen 2's 2,400 W, a 3,900 W surge for heating-type loads only to the Anker SOLIX C2000 Gen 2's 4,000 W, and 1,000 W of solar input to 800 W. The Anker SOLIX C2000 Gen 2's specs cover a fridge start; the Bluetti Elite 200 V2's do not.
  • Smaller: the Bluetti AC180 ($499) runs a fridge about 10 hours, but its specs do not confirm the fridge start.
  • Bigger: for $199.01 more, the Bluetti Elite 300 runs a fridge about 27 hours and a CPAP 11 nights.
  • Expanded: with the Anker SOLIX BP2000 Expansion Battery (Gen 2) ($749.99 when checked) it reaches 4.1 kWh: a fridge about 1.5 days, a CPAP 15.5 nights.

*Prices and specifications are from each manufacturer's US website, checked . Prices change often, sometimes daily during sales; the seller's page is the final word. Cycle ratings are the maker's own figures, measured to different end points, so treat them as rough guides.

Safe to run indoors. A battery power station makes no exhaust, so unlike a gas generator it can sit next to the fridge or the bed. Gas generators must run outdoors, at least 20 ft from windows and doors (Ready.gov).

Frequently asked questions

How long will the Anker SOLIX C2000 Gen 2 run a refrigerator?

About 18 hours for a typical US kitchen fridge, which uses 96 W averaged over the day (839 kWh a year, EIA). That is 1,741 usable Wh (2.05 kWh x 85%) divided by 96 W. Start-up is covered: EWEB's generator-sizing sheet puts a kitchen refrigerator at 700 W running plus 2,200 W to start, 2,900 W in all, and the Anker SOLIX C2000 Gen 2 can give a motor 4,000 W. A closed fridge keeps food safe about 4 hours without power (FoodSafety.gov), so running it in shifts stretches the battery further.

Can the Anker SOLIX C2000 Gen 2 run a space heater?

Yes, a 1,500 W heater on high is within its 2,400 W output, but only for about 1 hour. At 1,500 W it is the biggest steady load in the table above that the Anker SOLIX C2000 Gen 2 can run, so the battery is for taking the chill off, not heating a room through the night. On a thermostat that cycles, it lasts longer.

Can the Anker SOLIX C2000 Gen 2 run a CPAP, and for how many nights?

7.5 nights with the heated humidifier on (28 W, ResMed's AirSense 10 figure) and 19.5 nights with it off, at 8 hours a night. It switches to battery in 10 ms when the power drops, per Anker. Check your own machine's watts in its manual.

Can the Anker SOLIX C2000 Gen 2 run a sump pump?

Yes, for about 2 hours. That is hours of actual pumping for a 1/3 HP pump (800 W running, EWEB). A sump pump runs only when the pit fills, so in a light rain it can last much longer; in a storm it may run often.

Can the Anker SOLIX C2000 Gen 2 run a window air conditioner?

Not a 12,000 BTU unit at EWEB's 3,250 W running figure: that is more than its 2,400 W output. A smaller unit draws less; find the watts on its label. If they are under 2,400 W, divide 1,741 Wh by those watts for the hours it would run with the compressor on nonstop.

How can I make the Anker SOLIX C2000 Gen 2 last longer?

Add the Anker SOLIX BP2000 Expansion Battery (Gen 2) ($749.99 when checked) to reach 4.1 kWh, which runs a typical fridge about 1.5 days. It takes up to 800 W of solar, so panels can refill it during the day. Run only what you need, and switch the fridge on and off in shifts.
