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
With 12000 watts of surge capacity, this system can handle typical startup loads for central air compressors, well pumps, and other motor-driven equipment common in residential settings. The 6000-watt continuous rating supports sustained operation of multiple high-draw appliances simultaneously. The 6144 Wh capacity provides meaningful runtime for essential circuits during grid outages.
This unit uses lithium iron phosphate (LFP) chemistry, known for stable thermal behavior in stationary storage applications. The system is designed with internal protections typical of grid-tied and off-grid battery platforms. Source: EcoFlow DELTA Pro Ultra User Manual (manufacturer documentation).

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: ~12.3h. 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 Pro Ultra power a Portable Oxygen Concentrator?
Yes. The EcoFlow Delta Pro Ultra provides 6000W running / 12000W surge. The Portable Oxygen Concentrator needs 403W / 403W (including 15% buffer). That leaves 5597W of running headroom and 11597W of surge margin.
How long will the Delta Pro Ultra run a Portable Oxygen Concentrator?
Approximately 12.3 hours, based on the Portable Oxygen Concentrator's 350W draw and the Delta Pro Ultra's 6144Wh capacity (70% usable after real-world losses).
What Else Can You Run?
With 1015W allocated to the Portable Oxygen Concentrator, the Delta Pro Ultra still has ~3435W of margin. These devices could run simultaneously:
