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. | |||||

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 600 W surge window can support typical compressor-based startup loads found in small refrigerators, window AC units, and sump pumps. The 256 Wh capacity limits sustained runtime, but the 2:1 surge-to-running ratio can handle brief inrush currents during motor startup events. This unit can manage intermittent high-demand appliances in portable or backup scenarios.
LFP chemistry provides stable operation across discharge cycles. The 300 W continuous rating with 600 W surge headroom allows brief high-draw events without immediate overload shutdown. Source: EcoFlow RIVER 2 User Manual v1.0 (OEM 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: ~0.5h. 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 RIVER 2 power a Portable Oxygen Concentrator?
It depends on the model. 1 of 3 Portable Oxygen Concentrator models are compatible with the EcoFlow RIVER 2. See the model-specific results table for exact verdicts per model.
How long will the RIVER 2 run a Portable Oxygen Concentrator?
It depends on the model. Compatible models run approximately 1.2–1.2 hours on the RIVER 2. 2 of 3 models are not compatible. See the model-specific results for details.
Pro Tip for Medical Users: According to energy reports, turning off the humidifier on your Portable Oxygen Concentrator can double your runtime. Using a DC cable instead of the AC plug is also recommended to avoid inverter inefficiency.
