Can it run it?

What can the Anker SOLIX C1000 Gen 2 run, and for how long?

1.02 kWh of battery, 2,000 W continuous output. A 1 kWh unit with a real 3,000 W surge, so it starts every motor on our list that fits its 2,000 W output. Its limit is the battery: it is not expandable.

One appliance at a time from a full charge. Run time = 1.02 kWh x 85% usable (870Wh) 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 C1000 Gen 2 cannot run

  • 12,000 BTU window AC (3,250 W). Needs 3,250 W running; the Anker SOLIX C1000 Gen 2 gives 2,000 W.
  • An electric water heater. About 4,500 W (EWEB), more than twice what the Anker SOLIX C1000 Gen 2 puts out. Nor anything that needs 240 V: the Anker SOLIX C1000 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 2,000 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 100 V2 (opens in a new tab) ($499, checked November 9, 2026) has 1.02 kWh, so every run time above is the same. It has 1,800 W of output to the Anker SOLIX C1000 Gen 2's 2,000 W, a 3,600 W surge to the Anker SOLIX C1000 Gen 2's 3,000 W, and 1,000 W of solar input to 600 W.
  • Bigger: for $450 more, the Anker SOLIX C2000 Gen 2 runs a fridge about 18 hours and a CPAP 7.5 nights.
  • Need a different size? The home battery sizer and the outage backup calculator work it out from your own list of appliances.

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 C1000 Gen 2 run a refrigerator?

About 9 hours for a typical US kitchen fridge, which uses 96 W averaged over the day (839 kWh a year, EIA). That is 870 usable Wh (1.02 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 C1000 Gen 2 can give a motor 3,000 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 C1000 Gen 2 run a space heater?

Yes, a 1,500 W heater on high is within its 2,000 W output, but only for about 35 minutes. At 1,500 W it is the biggest steady load in the table above that the Anker SOLIX C1000 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 C1000 Gen 2 run a CPAP, and for how many nights?

3.5 nights with the heated humidifier on (28 W, ResMed's AirSense 10 figure) and 9.5 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 C1000 Gen 2 run a sump pump?

Yes, for about 1 hour. 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 C1000 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 2,000 W output. A smaller unit draws less; find the watts on its label. If they are under 2,000 W, divide 870 Wh by those watts for the hours it would run with the compressor on nonstop.

How can I make the Anker SOLIX C1000 Gen 2 last longer?

It is not expandable, so the only way is to recharge it. It takes up to 600 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.
