How many nights will the DJI Power 2000 run a CPAP without a humidifier?

About 31 nights of 8 hours (249 hours in total). A CPAP without a humidifier averages about 7 W, and the 2,048 Wh battery gives about 1,741 Wh after inverter losses.

How long does it last with a heated humidifier?

With the heated humidifier on (about 34 W), about 6 nights (2 days). Without it (about 7 W), about 31 nights (10 days). Turning the humidifier off is the easiest way to stretch a charge.

Is the DJI Power 2000 enough backup for a CPAP without a humidifier?

Only as a short bridge. It covers about 31 nights (249 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.
