EcoFlow DELTA Pro 3: runtime and specs
From EcoFlow's own product page, read November 2026. Runtimes use 85% of capacity, the planning figure Jackery and EcoFlow use.
Short answer
The EcoFlow DELTA Pro 3 stores 4,096 Wh and puts out 4,000 W continuously. It runs a typical bottom-freezer fridge about 2.3 days and a 1,000 W load about 3 h 29 min.
Runtime at a steady load
| Load | Runs for |
|---|---|
| 100 W | 34 h 49 min |
| 300 W | 11 h 36 min |
| 500 W | 6 h 58 min |
| 1,000 W | 3 h 29 min |
| 1,500 W | 2 h 19 min |
| 3,000 W | 1 h 10 min |
hours = 4,096 Wh × 0.85 ÷ watts
Runtime on a refrigerator
| Fridge (ENERGY STAR median) | Average draw | Runs for |
|---|---|---|
| Bottom-freezer fridge 560 kWh/yr | 64 W | 2.3 days |
| Top-freezer fridge 363 kWh/yr | 41 W | 3.5 days |
| Side-by-side fridge 640 kWh/yr | 73 W | 47 h 39 min |
| Compact fridge 246 kWh/yr | 28 W | 5.2 days |
A fridge's compressor cycles, so its average draw is far below its starting surge. For anything else, put its watts into the power station runtime calculator.
