How many nights will the Anker SOLIX F3800 Plus run a CPAP without a humidifier?

About 58 nights of 8 hours (466 hours in total). A CPAP without a humidifier averages about 7 W, and the 3,840 Wh battery gives about 3,264 Wh after inverter losses.

How long does it last with a heated humidifier?

With the heated humidifier on (about 34 W), about 12 nights (4 days). Without it (about 7 W), about 58 nights (19 days). Turning the humidifier off is the easiest way to stretch a charge.

Is the Anker SOLIX F3800 Plus enough backup for a CPAP without a humidifier?

Only as a short bridge. It covers about 58 nights (466 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.
