Runtime predictions for your loads
Based on 3,600 Wh capacity · 95% LiFePO4 DoD · 90% AC inverter efficiency. Solar column assumes ~25% of rated input as sustained sun average. Phase-1 uses constant-load math; time-resolved multi-day SOC simulation is the Phase-2 north star.
| Load profile | Continuous draw | Runtime estimate |
|---|---|---|
| CPAP only (overnight) | 60W | 2.1 days |
| Fridge only (cycle-averaged) | 70W | 1.8 days |
| Wifi router + LED lights | 55W | 2.3 days |
| Your full continuous load (215W) | 215W | 14.3 hr |
| Microwave + base load (peak) | 1300W | 2.4 hr |
| Window AC 8,000 BTU (avg) | 700W | 4.4 hr |
Detailed specs
Sourced from manufacturer datasheet · verified 1mo agoFor advanced shoppers. Plug types matter if you have a 30A RV; MPPT range matters if you plan custom solar arrays.
Battery behavior
| Cell chemistry | LiFePO4 |
| Cycle life @ 80% capacity | 3,500 |
| Dimensions | 25×11×16 |
| Parasitic loss (idle, AC off) | pending verification |
Why parasitic loss matters: for store-and-forget hurricane prep, even ~2W idle drain adds up — a fully charged unit can drain in months sitting in a closet.

RVer note: The EcoFlow DELTA Pro has a native TT-30R outlet — for a standard 30A RV you plug directly in, no adapter needed. For 50A RVs you'll need a TT-30 → 14-50 adapter, but you'll only get 120V on each leg, not split 240V.
