Show expert analysisTechnical: **Running load:** 150 W. **Surge:** 150 W. **Voltage:** 120 V AC. No inrush spike, consistent draw across flow settings. Field note: Verify power station inverter can deliver 150 W continuously for 24-hour cycles. Monitor battery state of charge during overnight operation. Can I run this concentrator on battery backup during a power outage? Only if your power source can supply at least 150W continuous and 150W surge at 120V. | |||||
| Philips EverFlo | 350W | 350W | Safe | ~4.1h | OEM Verified |
Show expert analysisTechnical: **Running load:** 350W continuous. **Surge:** 350W (no inrush spike). **Voltage requirement:** 120V AC. Resistive heating element drives steady draw with minimal transient. Field note: Ensure power station inverter handles 350W continuous without thermal cutoff. Voltage deviation beyond ±5% may trigger device fault alarms. Can I run this on a portable power station during an outage? Only if your power source can supply at least 350W continuous and 350W surge at 120V. Verify capacity in watt-hours exceeds your runtime need. | |||||

Show expert analysisTechnical: **Running load:** 310W continuous. **Surge:** 310W (no starting transient). **Voltage:** requires 120V AC. The device demands 7440 Wh over a 24-hour period. Field note: Medical oxygen concentrators tolerate no interruption. Verify the power station supports pass-through charging during mains operation. Can I run this oxygen concentrator on a portable power station during an outage? Only if your power source can supply at least 310W continuous and 310W surge at 120V.

Generator Insights
The 4800 W surge can support typical startup loads for refrigerators, well pumps, and air compressor motors that require momentary inrush current. The 2048 Wh capacity provides extended runtime for moderate continuous loads. This configuration can handle brief motor starts while sustaining steady power delivery for home backup scenarios.
This unit uses LFP chemistry, which offers a different thermal profile than older lithium chemistries. The manufacturer provides operational guidelines in their documentation.

Technical Analysis
Spec-Based • No GuaranteesTechnical Breakdown
Running range: 150W (portable SimplyGo) to 350W (stationary EverFlo). Surge: modeled equal to running — no OEM startup current published for any oxygen concentrator in this class. Voltage: 120V AC.
Expected Behavior
Estimated runtime: ~4.1h. Stationary concentrators operate 24 hours daily at constant draw, consuming 7,440-8,400 Wh per day. Portable units draw less but still require continuous power for uninterrupted oxygen delivery.
Field Note
Oxygen concentrators are life-critical — always have a backup power source. Use pure sine wave output only. Verify pass-through charging capability so the power station stays charged while the concentrator runs on mains power.
Frequently Asked Questions
Can the EcoFlow DELTA 2 Max power a Portable Oxygen Concentrator?
Yes. The EcoFlow DELTA 2 Max provides 2400W running / 4800W surge. The Portable Oxygen Concentrator needs 403W / 403W (including 15% buffer). That leaves 1997W of running headroom and 4397W of surge margin.
How long will the DELTA 2 Max run a Portable Oxygen Concentrator?
Approximately 4.1 hours, based on the Portable Oxygen Concentrator's 350W draw and the DELTA 2 Max's 2048Wh capacity (70% usable after real-world losses).
What Else Can You Run?
With 375W allocated to the Portable Oxygen Concentrator, the DELTA 2 Max still has ~1195W of margin. These devices could run simultaneously:
