Model-Specific Results
3 of 3 models are SAFE or TIGHT. Most demanding model: Drive Medical Power Neb Ultra (110W surge).
| Model | Running | Surge | Verdict | Runtime | Source |
|---|---|---|---|---|---|
| Omron CompAir NE-C801 | 12W | 12W | Safe | ~29.9h | Engineering Est. |
Show expert analysisTechnical: **Running load:** ~12W AC (12V × 0.8A DC via external AC adapter). **Surge:** ~12W (DC-powered, no motor inrush at the AC side). **Voltage:** 100-240V AC input (universal adapter). This is the lowest-draw nebulizer in this comparison by a wide margin — the external DC adapter eliminates AC-side compressor surge. Field note: The Omron NE-C801 is the most portable-power-friendly nebulizer available. At only 12W, even a 150Wh power bank with AC output can provide over 10 hours of therapy. The DC adapter also means modified sine wave inverters are less of a concern — the adapter handles AC conversion internally. Always carry a backup adapter. Can I run the Omron CompAir nebulizer on a small portable power station? Only if your power source can supply at least 12W continuous at 120V. This device draws minimal power and is compatible with virtually any power station or battery pack with an AC outlet. | |||||
| PARI PRONEB Max | 98W | 98W | Safe | ~3.7h | Gov. Database |
Show expert analysisTechnical: **Running load:** 98W (FDA 510(k) filing, under normal load). **Surge:** 98W (OEM surge data not published — shaded pole motors have low inrush characteristics). **Voltage:** 120V AC, 60 Hz. The PRONEB Max uses an AC-powered shaded pole motor driving an oil-free piston compressor at 30+ psig. Field note: The PARI PRONEB Max is the current hospital-grade standard, replacing the PARI Vios. At 98W it requires a power station with at least 200W continuous output. For respiratory therapy on battery backup, pure sine wave output is recommended — AC shaded pole motors may run hot or lose efficiency on modified sine wave inverters. This is a life-sustaining medical device: always have a backup power source. Can I use the PARI PRONEB Max nebulizer during a power outage with a portable power station? Only if your power source can supply at least 98W continuous at 120V. Pure sine wave output is recommended for this AC motor-driven compressor. Always maintain a backup power source for life-sustaining respiratory therapy. | |||||
| Drive Medical Power Neb Ultra | 110W | 110W | Safe | ~3.3h | OEM Manual |
Show expert analysisTechnical: **Running load:** 110W (110 VA OEM rated — apparent power, conservative for sizing). **Surge:** 110W (OEM surge data not published — piston compressor motor has some startup inrush but OEM does not specify). **Voltage:** 120V AC, 60 Hz. The Power Neb Ultra uses a piston-driven AC motor compressor producing 30+ psig at 8 LPM free air flow. Field note: The Drive Medical Power Neb Ultra is the most common insurance-reimbursed nebulizer in the US. At 110 VA it draws the most power in this comparison. Pure sine wave output is recommended for the AC piston motor. The 110 VA rating is apparent power — real watts may be lower, but size your power station to the VA rating for safety. This is a medical device: always have a backup power source. Can I run the Drive Medical nebulizer on a portable power station during an outage? Only if your power source can supply at least 110W continuous at 120V. Pure sine wave output is recommended for this AC motor-driven compressor. Always maintain a backup power source for respiratory therapy. | |||||

Generator Insights
The 1000W surge can handle typical compressor startup events in refrigerators, window AC units, and well pumps that fall within momentary draw limits. Sustained loads must stay at or below 500W to avoid shutdown. This is a light-duty unit for essential circuits, not whole-home backup.
This portable station uses LFP chemistry, known for thermal stability in consumer lithium batteries. The 512Wh capacity and 500W continuous rating provide a workable buffer for appliances within spec. Source: EcoFlow RIVER 2 Max User Manual v1.0 (manufacturer documentation).

Technical Analysis
Spec-Based • No GuaranteesTechnical Breakdown
Running load: 12–110W depending on model. Surge: OEM surge data not published for any model in this class. Voltage: 120V AC required (except Omron which uses a universal 100-240V adapter). Medical nebulizers range from ultra-compact DC-powered units (Omron, 12W) to hospital-grade AC compressors (Drive Medical, 110 VA).
Expected Behavior
Estimated runtime: ~3.3h. Nebulizers run continuously during 15-30 minute therapy sessions, typically 2 hours total daily. Daily energy consumption ranges from 24 Wh (Omron) to 220 Wh (Drive Medical). No cycling or duty-cycle behavior — compressors run steady until switched off.
Field Note
For AC motor-driven nebulizers (PARI, Drive Medical), pure sine wave inverter output is recommended — shaded pole and piston motors may overheat or lose efficiency on modified sine wave. The Omron DC-powered model is less sensitive to waveform quality. This is life-sustaining medical equipment: always have a backup power source and never rely on a single battery.
Frequently Asked Questions
Can the EcoFlow RIVER 2 Max power a Nebulizer?
Yes. The EcoFlow RIVER 2 Max provides 500W running / 1000W surge. The Medical Nebulizer Machine needs 127W / 127W (including 15% buffer). That leaves 373W of running headroom and 873W of surge margin.
How long will the RIVER 2 Max run a Nebulizer?
Approximately 3.3 hours, based on the Medical Nebulizer Machine's 110W draw and the RIVER 2 Max's 512Wh capacity (70% usable after real-world losses).
What Else Can You Run?
With 290W allocated to the Medical Nebulizer Machine, the RIVER 2 Max still has ~0W of margin. These devices could run simultaneously:
