Will it run your setup? Check in 20 seconds
Estimates use 85% usable capacity and 70% of rated solar output. Real results vary with temperature, inverter load, shade and appliance cycling. Fridge and freezer watts are daily averages and do not include compressor startup surges.
Runtime by appliance, one at a time
Simple energy estimates, not measured runtimes. About 898Wh usable on the C1000 and 1,741Wh on the C2000 Gen 2.
Appliance for appliance, the C2000 Gen 2 lasts 94% longer than the C1000.

The price gap, in numbers
The Anker SOLIX C2000 Gen 2 costs $470 more than the Anker SOLIX C1000 and adds 992Wh: that is $0.47 per extra Wh, against $0.45 per Wh for the C1000.
Prices refresh daily from Anker US.What the $470 buys: nearly twice the battery (2,048Wh vs 1,056Wh), 2,400W instead of 1,800W and a 10ms UPS.
1 × C2000 Gen 2 (2,048Wh) costs $9.99 less today.
The lifetime figure divides the price by the rated cycles to 80% times the capacity: 3,000 for the C1000, 4,000 for the C2000 Gen 2. Read it as a ranking, not a bill. Two C1000s give you two separate 1,800W stations you can carry one at a time; one C2000 Gen 2 puts 2,048Wh behind a 2,400W inverter with a TT-30. Anker US prices move often; the figures here are refreshed daily by our price engine.
The third option: the C1000 Gen 2 at $529.99
Anker SOLIX C1000 Gen 2: $529.99 today
1,024Wh, 2,000W from five outlets, a 10ms UPS and a 49-minute UltraFast refill above 68°F, at 24.9 lb. OutdoorGearLab measured 890Wh out of it. It can’t be expanded. Pick it for the lightest 1kWh in Anker’s range. Our C1000 Gen 2 review goes deeper. See the C1000 Gen 2 at Anker.
Eight modeled situations, worked out
Same formula as the calculator above, with 0 extra batteries unless stated. The fridge averages 60W, about 525kWh a year, in the range printed on typical EnergyGuide labels; that average does not include compressor startup surges.
24-hour outage, essentials only
The C2000 Gen 2 gets through the night and most of the next day; the C1000 covers an evening and the night.
CPAP, two nights
Both cover two nights; the C1000 is the one you’d pack.
Breakfast during an outage
Only the C2000 Gen 2 runs both at once. On the C1000, run them one after the other.
Refill from solar, max panels
The C1000 refills its smaller battery sooner; the C2000 Gen 2 banks more energy per hour of sun.
Two nights in an RV
The C2000 Gen 2 is the RV unit: a TT-30 for the RV inlet, twice the battery and 800W alternator charging. The C1000 has no TT-30.
Home office through an outage
The C2000 Gen 2 switches in 10ms and carries the workday and night; Anker’s US page lists UPS on the C1000 without a switchover time.
A full-size fridge, nothing else
The C2000 Gen 2 keeps food cold about 14.1 h longer on one charge. With solar during the day, either can carry a fridge through a multi-day outage.
A 1,500W space heater on high
Heaters drain any portable station fast. Use the low setting and treat the station as a bridge, not a heating plan.

Practical consequence: the C1000 has more household outlets and a light bar; the C2000 Gen 2 adds the TT-30 RV port and faster laptop USB-C.
09 · NoiseNoise: C1000 vs C2000 Gen 2
The Anker SOLIX C2000 Gen 2 is the quieter one: Notebookcheck measured about 35dB under high load, while OutdoorGearLab found the Anker SOLIX C1000‘s fan one of the loudest it reviewed at maximum load.
Anker rates the C2000 Gen 2 at 30dB under 1,000W and publishes no rating for the C1000.Every figure we found, with its source
No decibel figure published.
What reviewers heard: Its fan at maximum load was one of the loudest of all the power stations it reviewed (OutdoorGearLab); the small fans sound slightly harsh near maximum AC load (Trusted Reviews, UK unit).
What reviewers heard: Even at full power the fans stay a subdued whirr (Trusted Reviews, UK unit); quiet enough to sleep next to in a tent or bedroom (AndroidGuys).
Measured by a tester Brand figure
- Cap the AC charging speed in the Anker app overnight.
Cold, heat and storage: C1000 vs C2000 Gen 2
The Anker SOLIX C1000 and the Anker SOLIX C2000 Gen 2 share the same limits: charging from 32°F to 104°F, running from −4°F to 104°F. Neither has a water rating.
Figures from the Anker US pages and the C2000 Gen 2 user guide.- In a garage or an RV in winter, bring either one inside to recharge: neither charges below 32°F.
- For long storage, recharge to 100% if the level drops below 30%: Anker says to check the C2000 Gen 2 monthly, and to store the C1000 dry and cool, outputs off, with a full charge every 3 months.
App, UPS and smart features
The Anker SOLIX C2000 Gen 2 does more: a documented 10ms UPS, Time-of-Use and Storm Guard modes, and wall plus solar charging together. The Anker SOLIX C1000 covers the basics in the same app.
Both use the Anker app over Wi-Fi and Bluetooth and take one extra battery.Does it prepare for storms? The Anker SOLIX C2000 Gen 2’s Storm Guard and Fast Charging Plan modes store backup power for outages and storms; Anker lists no such mode for the C1000.
Can it charge off-peak? The Anker SOLIX C2000 Gen 2 has a Time-of-Use mode; the Anker SOLIX C1000 offers power scheduling in the app.
Can it charge from wall and solar at once? Per Anker’s FAQ, the Anker SOLIX C1000 can’t combine AC and solar; the Anker SOLIX C2000 Gen 2 combines them up to 2,600W.
Does it work as a UPS? The Anker SOLIX C2000 Gen 2 switches in 10ms; Anker lists UPS on the Anker SOLIX C1000 without a switchover time.
Can you add a battery later? Both take one expansion battery: the Anker SOLIX C1000 grows to 2,112Wh, the Anker SOLIX C2000 Gen 2 to 4,096Wh.
Can it run a heater or kettle above its rating? Both have SurgePad for heating appliances, not motors: up to 2,400W on the Anker SOLIX C1000 and 3,000W on the Anker SOLIX C2000 Gen 2.
Warranty and support

Practical limits before you buy
- The C1000 stops at 1,800W. A microwave and a coffee maker together overload it.
- The C1000 has no TT-30. An RV needs an adapter from a standard outlet.
- The C1000 can’t charge from AC and solar together. AC takes priority.
- Check the C1000’s expansion battery. The BP1000 page didn’t load for our price engine on October 30, 2026; confirm availability before counting on it.
- SurgePad is for heating loads only.
- Solar cables are extra on both.
- 41.7 lb vs 28.4 lb. The C2000 Gen 2 is a two-hand carry.
- C1000, per its US documentation: AC and DC inputs cannot charge at the same time; AC input takes priority, then it switches to DC when AC charging ends.
- C1000, per its US documentation: SurgePad (up to 2,400W) works best with heat-generating devices and does not support precision instruments or voltage-sensitive devices.
- C1000, per its US documentation: Storage: turn off outputs, store dry and cool, recharge to 100% if below 30%, fully charge every 3 months.
- C1000, per its US documentation: Charging temperature 32 to 104F; discharging -4 to 104F. Max AC input 1,300W, solar 600W (11-60V).
- C2000 Gen 2, per its US documentation: When the 15W USB-C and 12W USB-A ports are used together, total output is limited to 20W.
Frequently asked questions
What is the difference between the Anker C1000 and the C2000 Gen 2?
The C2000 Gen 2 has twice the battery (2,048Wh vs 1,056Wh), 2,400W instead of 1,800W, a TT-30 RV port and 800W of solar. The C1000 is lighter, charges from the wall in 58 minutes and has six AC outlets.
How long will each run a refrigerator?
At a 60W average: about 15 hours on the C1000 and 29 hours on the C2000 Gen 2.
Which is better for an RV?
The C2000 Gen 2: TT-30 port, twice the battery and 800W alternator charging.

Yes, with one battery each: the C1000 to 2,112Wh, the C2000 Gen 2 to 4,096Wh.
Can the C1000 run a microwave?
A typical microwave alone, yes. With a second big appliance at the same time, no.
Which is better as a UPS?
The C2000 Gen 2, rated at 10ms; Anker’s US page gives no switchover time for the C1000.
How much do they weigh?
28.4 lb for the C1000 and 41.7 lb for the C2000 Gen 2.
Do reviews confirm the rated capacity?
C1000: On AC output the C1000 delivered 897Wh, about 85% of its rated 1,056Wh (OutdoorGearLab). C2000 Gen 2: At a steady 200W AC load only about 1,600Wh came out, just under 79%; at 1,800W about 1,850Wh, roughly 90% (Notebookcheck, EU unit). Inverter losses usually take 10 to 20% on AC, which is why our calculator uses 85% of the rating.
How loud are the C1000 and the C2000 Gen 2?
C1000: no official rating. C2000 Gen 2: 30dB under 1,000W per Anker; Notebookcheck measured about 35dB at 1 m (EU unit). Fans run hardest during fast charging and near full output.
