Philips DreamStation, worst case at the 80 W power supply rating
Philips DreamStation, worst case at the 80 W power supply rating draws 80 W while on, and about 80 W after its published duty cycle.
Medical safety notice: Will It Run? gives general power estimates only, not medical advice. Power draw varies by model, settings, pressure, humidifier and altitude. Before relying on any battery, power station, inverter or generator for a medical device, confirm approved power sources with the device manufacturer and your doctor or equipment supplier, and test your setup before an emergency. Never change prescribed settings to extend battery life. If your therapy is life-sustaining, keep the backup your supplier provides, register with your utility's medical-needs program, and have an evacuation plan. Run generators outdoors only, at least 20 ft from windows and doors, because of carbon monoxide risk. In an emergency, call 911.
An 8-hour night uses about 640 Wh. Compare every CPAP and BiPAP setting on the CPAP hub.

| Source | https://www.documents.philips.com/doclib/enc/11410694/DreamStation_Humidifier_User_Manual.pdf Philips does not publish a typical DreamStation draw. The DreamStation Heated Humidifier manual lists the 80 W power supply and DC power consumption of 12 VDC at 6.67 A (80 W). Willrun uses that ceiling as a worst case, so real nights will usually last longer. Heated tubing is powered through the humidifier. |

Anker SOLIX F3800 row: uses about 40 W of idle draw instead of 15 W, because Anker's FAQ for the F3800 Plus lists about 40 W with AC on and nothing connected (Anker; F3800 idle table).
How AC runtime is figured: usable Wh (nameplate × 0.85) ÷ (CPAP watts + about 15 W). The 15 W is the inverter's own draw just to stay on: BLUETTI counts about 15 W of self-consumption in its AC180 runtime formula, and an owner test measured about 17.5 W idle on a DELTA 3 Plus. Larger stations can idle higher, so test your own setup before you rely on it. DC figures skip the inverter and are a best case. Method and DC converter limits: CPAP power station guide. — means no DC figure: Philips doesn't publish a DC draw for this worst-case row. Use only the Philips Respironics DC cord.

Questions
What number does Willrun compare to the inverter?
Running watts of 80 W must fit under continuous output. Startup watts were not published.
How is runtime calculated?
On AC: usable watt-hours (capacity × 0.85) divided by (80 W + about 15 W of inverter draw). On DC with the maker's converter there is no inverter, so the best case divides by 80 W alone.
Where did this come from?
Philips does not publish a typical DreamStation draw. The DreamStation Heated Humidifier manual lists the 80 W power supply and DC power consumption of 12 VDC at 6.67 A (80 W). Willrun uses that ceiling as a worst case, so real nights will usually last longer. Heated tubing is powered through the humidifier.
