How Long Will the EcoFlow River 2 Run a Nebulizer?
Updated 2026-10-17 · Yes
Medical equipment: these are estimates. Test your own setup and keep a backup plan.
The numbers
| Battery capacity | 256Wh (LFP) |
|---|---|
| Usable energy | 218Wh (85% via AC outlets) |
| Continuous AC output | 300W |
| Surge rating | 600W |
| Nebulizer running watts | 80W |
| Startup watts | 120W |
| Average draw | 80W |
| Estimated runtime | 2.7 hours |
| Energy per day of typical use | 80Wh |
256Wh × 0.85 = 218Wh usable ÷ 80W average = 2.7 hours

Recharging with solar
The EcoFlow River 2 accepts up to 110W of solar input. In real conditions that harvests about 413Wh on a sunny day (5 peak-sun hours).
Solar can keep up. A nebulizer uses about 80Wh a day at 1 hours of use, so with enough panels and good sun the EcoFlow River 2 can run it indefinitely.
Tips
- Compressor nebulizers use little energy because treatments last 10–15 minutes.
- You’ll still have about 220W of AC capacity left for other devices at the same time, though they’ll share the same battery.
- The EcoFlow River 2 uses LiFePO4 (LFP) cells, rated for thousands of cycles, so running it down daily won’t wear it out quickly.

FAQ
How long does the EcoFlow River 2 take to recharge with solar?
With its maximum 110W of solar input it refills in about 3.1 hours of strong sun. A single 200W panel is enough to max out its solar input.
Is the EcoFlow River 2 safe for medical equipment?
These are estimates, not medical advice. Check your device’s actual power draw, test your setup before you rely on it, and always keep a backup plan approved by your doctor or equipment supplier.
