How many nights will the Anker SOLIX C1000 Gen 2 run a CPAP with heated humidifier?

About 3 nights of 8 hours (26 hours in total). A CPAP with heated humidifier averages about 34 W, and the 1,024 Wh battery gives about 870 Wh after inverter losses.

How much longer does it last without the heated humidifier?

With the heated humidifier on (about 34 W), about 3 nights (26 hrs). Without it (about 7 W), about 15 nights (5 days). Turning the humidifier off is the easiest way to stretch a charge.

Is the Anker SOLIX C1000 Gen 2 enough backup for a CPAP with heated humidifier?

Only as a short bridge. It covers about 3 nights (26 hours) from a full charge. A power station should never be your only backup for medical equipment: ask your equipment supplier what they provide in an outage, register with your utility’s medical-needs program, and keep the settings your prescriber gave you.
