Can the EcoFlow DELTA Pro 3 Run a Compact Mini-Fridge?
✅ Yes — the EcoFlow DELTA Pro 3 can run a Compact Mini-Fridge. Its 4000W continuous output covers the 100W draw, and its 8000W surge rating covers the 400W startup spike, giving roughly 30.7 hours of continuous running.

The Checks, One by One
| Check | Result | Detail |
|---|---|---|
| Running watts | ✅ pass | 4000W continuous output covers the appliance's 100W running draw, leaving 3900W of headroom. |
| Startup surge | ✅ pass | 8000W surge rating covers the appliance's 400W startup spike. |
| Runtime | ℹ️ info | 4096Wh of battery at a 75% AC-inverter efficiency factor gives roughly 30.7 hours of continuous running at 100W. |

How Long It Would Run
At a continuous 100W draw, the EcoFlow DELTA Pro 3's 4096Wh battery gives roughly 30.7 hours after accounting for a 75% AC-inverter efficiency factor.
A compact mini-fridge does not draw power continuously — it cycles. At a realistic 40% duty cycle, expect closer to 76.8 hours of real-world coverage.
About This Appliance
A fridge compressor cycles rather than running continuously, so real-world energy use is well below the nameplate running watts multiplied by 24 hours.

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 2026-09-26; appliance figure from data/use-cases/mini-fridge.json (compact_mini_fridge), sourced from gridwright.com mini-fridge wattage data.
