What EcoFlow DELTA 3800 Gen4 Portable Power Station runs on a single charge
Runtime estimates below use our portable power station runtime calculator at 85% usable AC capacity across four reference loads from data/appliances.json.
| Appliance load | Reference draw | Estimated runtime | Notes |
|---|---|---|---|
| Full-size refrigerator (cycling) | 1.5 kWh/day (62.5 W average cycling draw, U.S. DOE) | 27.9 hours | About 1.2 days at 85% usable AC capacity |
| CPAP without heated humidifier | 11 W continuous (ResMed AirSense 10 Battery Guide) | 158.3 hours | About 19.8 eight-hour nights |
| Wi-Fi router + laptop computer | 60 W combined (10 W router + 50 W laptop, Penn State EME 807) | 29.0 hours | Continuous remote-work load at 85% usable AC capacity |
| Portable electric space heater (high) | 1,500 W resistive heat (Penn State EME 807) | 1.2 hours | Exceeds continuous AC rating (not stated); would drain 2,048 Wh in 1.2 hours |
