Answer
Can the EcoFlow RIVER 2 Pro run Philips DreamStation, worst case at the 80 W power supply rating?
Runs
Runs. Draw is 80 W, within the 800 W continuous output. Estimated runtime on AC: about 6.9 hr, counting about 15 W of inverter draw.
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.

The comparison
| EcoFlow RIVER 2 Pro | Philips DreamStation, worst case at the 80 W power supply rating | |
|---|---|---|
| Continuous output / running draw | 800 W | 80 W |
| Capacity / average draw | 768 Wh nameplate, 653 Wh usable | 80 W |
| Runtime on AC | 6.9 hr (80 W + about 15 W inverter draw) | |
| Nights on AC (8 hr) | 0.9 | |
| On DC, best case | Not modeled: Philips doesn't publish a DC draw for this worst-case row. Use only the Philips Respironics DC cord. | |
| Sources | Station source | Appliance source |
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.

Questions
Can the EcoFlow RIVER 2 Pro run Philips DreamStation, worst case at the 80 W power supply rating?
Runs. Draw is 80 W, within the 800 W continuous output. Estimated runtime on AC: about 6.9 hr, counting about 15 W of inverter draw.
How was the runtime calculated?
On AC: 768 Wh × 0.85 = 653 Wh usable, divided by (80 W + about 15 W inverter draw) = 6.9 hr. Not modeled: Philips doesn't publish a DC draw for this worst-case row. Use only the Philips Respironics DC cord.
Where did the numbers come from?
Product spec: 768 Wh, pure sine wave, 800 W total (surge 1,600 W). Comparison table lists the same 1,600 W as X-Boost, 4 AC outlets, and 17.2 lb. Treated as resistive boost, not motor-start capacity. 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.
