Anker SOLIX C2000 Gen 2

Q: How many nights will the Anker SOLIX C2000 Gen 2 run a CPAP?

A ResMed AirSense 11 at its typical 56 W runs about 23 hours on AC power: 2.8 nights of 8 hours. ResMed's typical figure includes its humidifier; a higher humidifier or heated-tube setting raises the draw. Running the CPAP from the 12 V socket with ResMed's DC converter avoids the inverter's own draw.

Q: How long does the Anker SOLIX C2000 Gen 2 take to charge?

Anker SOLIX states 88 min to full from a wall outlet, and up to 800 W of solar input.

Q: Can you add batteries to the Anker SOLIX C2000 Gen 2?

Yes. Anker SOLIX states it expands to 4,096 Wh with its extra batteries.

Q: What battery does the Anker SOLIX C2000 Gen 2 use?

LFP, rated by Anker SOLIX for 4,000 cycles to 80%.

A 2,048 Wh LFP station with 2,400 W of AC output (4,000 W peak) that weighs 41.7 lb, recharges from a wall outlet in 88 minutes and expands to 4,096 Wh. It suits outage backup for a refrigerator, router and sump pump for part of a day on one charge, or an RV trip with a microwave on board.

Strengths

2,400 W continuous and 4,000 W peak: starts a 1/2 HP sump pump that draws 2,645 W at start-up and runs it for about 1.8 hours (sizing for a sump pump).
Expands to 4,096 Wh; the Jackery Explorer 2000 v2 does not take an expansion battery.
800 W of solar input and six AC outlets, against 400 W and three outlets on the Jackery Explorer 2000 v2.
10 ms UPS switchover (the Explorer 2000 v2 lists 20 ms) and three USB-C ports, up to 140 W.
Runs a 25 cu ft French-door refrigerator (70 W average) for about 19 hours. With an eero 6+ router and a 1/2 HP sump pump running half an hour a day, the three need 2,685 Wh a day, and one charge covers 63% of that.

Limits

41.7 lb: heavier than the Jackery Explorer 2000 v2 (39.5 lb), lighter than the EcoFlow DELTA 3 Max (44.8 lb).
Expansion stops at 4,096 Wh; the DJI Power 2000 expands to 22,528 Wh and the Dabbsson DBS2300 Plus to 8,330 Wh.
4,000 W peak, below the 4,400 W Jackery lists for the Explorer 2000 v2 and the 4,800 W EcoFlow lists for the DELTA 3 Max.
