Our notes

The C2000 Gen 2 is one of the lightest 2 kWh stations in our database: 2,048 Wh in 41.7 lb, about 49 Wh per pound. Among 2 kWh models only the Jackery Explorer 2000 v2 does better. It replaced Anker's F2000 (767), which weighed 67.2 lb for the same capacity.

Against EcoFlow's DELTA 3 Max, also 2,048 Wh and 2,400 W, it's 3 lb lighter, takes 800 W of solar instead of 500 W, and can grow to 4,096 Wh with one BP2000 battery, which the DELTA 3 Max can't. The DELTA 3 Max has the higher surge rating, 4,800 W against 4,000 W. Both switch over in 10 ms.

On its own it runs a typical fridge for about 30 hours, or a 1/2 HP sump pump for about 8. It has five standard outlets plus a TT-30R for an RV, and a full wall charge takes about an hour and a half at 1,800 W.

Simulated runtimes (not measured)

Nobody tested this unit for this page. These figures come from a computer simulation of the C2000 Gen 2, and they are estimates. The plain runtime table below divides energy by average draw at 85% efficiency. The simulation also charges the battery for the power the inverter burns just by being switched on, which is why small loads come out shorter. Where we have measured a unit, the measurement is shown separately and labeled as measured.

Nonstop runtime from full to battery cutoff. Likely range = middle 80% of 200 simulated runs with the uncertain inputs varied. The inverter idle draw is assumed, not published: we assumed about 22 W for this model, varied from 13 to 34 W. If the real figure is lower, real runtimes land closer to the spec-sheet column.

How this was simulated
  • The battery is stepped down every 2 minutes until it reaches cutoff, for 200 runs per device. Results are seeded, so the page shows the same numbers on every build.
  • Battery draw = load + inverter idle draw + 4–8% of the load + a loss that rises with load squared (4% at full output).
  • Usable capacity = 92–98% of rated Wh, for protection cutoff and aging.
  • At 0 °C, 80–90% of that capacity is assumed available.
  • Fridges cycle on and off every 30–50 minutes at the share of the time set by their average draw. The inverter idle draw continues while the compressor is off.
  • Devices that exceed this model's output or surge rating are left out. Loads are US 120 V devices.

Questions

How long will the Anker SOLIX C2000 Gen 2 run a refrigerator?
About 30 hours for a typical ENERGY STAR full-size fridge averaging 58 W, assuming 85% inverter efficiency. Older or larger fridges use more. Try your own numbers.
Can the Anker SOLIX C2000 Gen 2 run a microwave?
Yes. A typical 1,000 W microwave pulls about 1,500 W from the outlet, within its 2,400 W continuous output. A full battery gives about 1.2 hours of cooking.
How many amp-hours is the Anker SOLIX C2000 Gen 2?
The Anker SOLIX C2000 Gen 2 works out to about 171 Ah at 12 V, or 160 Ah at 12.8 V, the nominal voltage of a 12 V LiFePO4 battery. Both are our conversion of Anker SOLIX's 2,048 Wh rating: amp-hours = watt-hours ÷ volts. The battery inside may run at a different voltage, so an amp-hour figure in a manual or on a product listing can look very different for the same energy. For scale, a 12 V 100 Ah LiFePO4 battery holds 1,280 Wh, so this model holds about as much as 1.6 of them. How we convert amp-hours.
How long does the Anker SOLIX C2000 Gen 2 take to charge?
Anker SOLIX's published charging claim: “100% in 1 h 28 min (1,800W AC); 58 min with AC + solar”. Max AC charging power is 1,800 W. With solar, it accepts up to 800 W. With 800 W of panels that's roughly 3.4 hours of good sun from empty.
Is the Anker SOLIX C2000 Gen 2 expandable?
Yes, up to 4,096 Wh with Anker SOLIX's extra batteries.
Does the Anker SOLIX C2000 Gen 2 work as a UPS?
Anker SOLIX lists a 10 ms switchover time, so it can keep devices like routers and computers running when the power drops. Check that your specific device tolerates the switch before relying on it for anything critical.
