Can the Renogy Lycan 5000 Power Box Run a RV Fridge?
✅ Yes — the Renogy Lycan 5000 Power Box can run a RV Fridge. Its 3500W continuous output covers the 250W draw, and its 7000W surge rating covers the 600W startup spike, giving roughly 14.4 hours of continuous running.

The Checks, One by One
| Check | Result | Detail |
|---|---|---|
| Running watts | ✅ pass | 3500W continuous output covers the appliance's 250W running draw, leaving 3250W of headroom. |
| Startup surge | ✅ pass | 7000W surge rating covers the appliance's 600W startup spike. |
| Runtime | ℹ️ info | 4800Wh of battery at a 75% AC-inverter efficiency factor gives roughly 14.4 hours of continuous running at 250W. |

How Long It Would Run
At a continuous 250W draw, the Renogy Lycan 5000 Power Box's 4800Wh battery gives roughly 14.4 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 36 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.
