System standby power: 15W (25.8% of total draw)
Provides 5× BS 1363 (230V), 1× CEE 7/3 (230V) (120V 60Hz).
Pure sine wave inverter output. Safe for sensitive medical electronics and variable-speed motors.
Inductive motor/compressor load with 1.6× starting surge (motor inrush) (97.3% worst-case surge margin).
Wall AC fast charge at up to 1300W (43m to 80%, 58m to 100%).
Safe envelope verified: Starting surge (65W) remains comfortably below the 2400W surge trip line, with steady-state operation settling into the safe continuous zone at 40W.
About 18.1 hours on AC power, with the CPAP machine averaging 40 W (standard pressure with humidifier active (40 W)). The Anker SOLIX C1000 then draws about 58 W from its battery, including 15 W for the inverter itself. Best case: about 34 hours (humidifier and heated tube off (15 W)). Worst case: about 12.4 hours (high pressure with HumidAir and heated tube at max (65 W)). At 8 hours a night, that's about 2.3 nights.
Yes. Using the ResMed Air11 90 W DC/DC Converter (part 39231) on the Anker SOLIX C1000's 12 V car socket, the CPAP machine runs about 27 hours instead of 18.1 hours on AC, 49% longer, because it skips the inverter's conversion loss and its 15 W idle draw. That's 3.4 nights instead of 2.3 nights.
That simple division gives 26 hours, but the Anker SOLIX C1000's inverter draws about 15 W whenever its AC outlets are on. At this light load that's 26% of everything the battery supplies, and inverter conversion losses take a further share. Anker SOLIX doesn't publish an idle figure and we haven't found an independent measurement, so this uses our 15 W estimate.
On wall power: about 43 minutes to 80% and 58 minutes to full (Anker SOLIX figures). With its maximum 600 W of solar input connected, expect about 480 W in full sun, so a full recharge takes roughly 2.3 hours of full sun, so it can refill in a single day with 4 peak sun hours.
It can act as a backup supply: with the CPAP machine plugged into the Anker SOLIX C1000 and the Anker SOLIX C1000 plugged into the wall, it switches the CPAP machine to battery in about 20 ms when the grid fails (Anker SOLIX calls this UPS mode).
