Can the EcoFlow RIVER 2 Max Run a RV Fridge?
✅ Yes — the EcoFlow RIVER 2 Max can run a RV Fridge. Its 500W continuous output covers the 250W draw, and its 1000W surge rating covers the 600W startup spike, giving roughly 1.5 hours of continuous running.

The Checks, One by One
| Check | Result | Detail |
|---|---|---|
| Running watts | ✅ pass | 500W continuous output covers the appliance's 250W running draw, leaving 250W of headroom. |
| Startup surge | ✅ pass | 1000W surge rating covers the appliance's 600W startup spike. |
| Runtime | ℹ️ info | 512Wh of battery at a 75% AC-inverter efficiency factor gives roughly 1.5 hours of continuous running at 250W. |

How Long It Would Run
At a continuous 250W draw, the EcoFlow RIVER 2 Max's 512Wh battery gives roughly 1.5 hours after accounting for a 75% AC-inverter efficiency factor.
A rv fridge does not draw power continuously — it cycles. At a realistic 40% duty cycle, expect closer to 3.8 hours of real-world coverage.
About This Appliance
Compressor-driven RV fridges draw meaningfully more than a compact mini-fridge.

Methodology
Verdict computed from this project's verified entity data using the same gates as its use-case scoring: waveform requirement first (an unconfirmed inverter type fails rather than passing), then continuous watts, then startup surge, then runtime at a 75% AC-inverter efficiency factor. Entity specs verified 2026-09-13; appliance figure from data/use-cases/mini-fridge.json (rv_fridge), sourced from parkingday.org RV fridge wattage data.
