Answer

Can the EcoFlow DELTA 3 Plus run ResMed AirSense 10 AutoSet, no humidifier?

Runs

Runs. Draw is 7 W, within the 1,800 W continuous output. Estimated runtime on AC: about 39.6 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.

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 DELTA 3 Plus run ResMed AirSense 10 AutoSet, no humidifier?

Runs. Draw is 7 W, within the 1,800 W continuous output. Estimated runtime on AC: about 39.6 hr, counting about 15 W of inverter draw.

How was the runtime calculated?

On AC: 1,024 Wh × 0.85 = 870 Wh usable, divided by (7 W + about 15 W inverter draw) = 39.6 hr. On DC with the ResMed Air10 DC/DC converter 90W in the car port there is no inverter, so the best case is 870 Wh divided by 7 W = 5.2 days.

Where did the numbers come from?

US spec table: 1,024 Wh, 6 outlets, 1,800 W (surge 3,600 W), X-Boost 2,200 W, about 12.5 kg (27.6 lb), LFP, 4,000 cycles to 80%+. ResMed's therapy-device power table (ResMed Deutschland, Art.-Nr. 1018528/11) lists AirSense 10 AutoSet at 7 Wh during operation. Energy per hour equals average watts, so the average draw is 7 W. ResMed notes the values were measured in a lab and that a local meter can differ.
