What Anker SOLIX Anker 521 PowerHouse - 256Wh 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) | 3.5 hours | About 0.1 days at 85% usable AC capacity |
| CPAP without heated humidifier | 11 W continuous (ResMed AirSense 10 Battery Guide) | 19.8 hours | About 2.5 eight-hour nights |
| Wi-Fi router + laptop computer | 60 W combined (10 W router + 50 W laptop, Penn State EME 807) | 3.6 hours | Continuous remote-work load at 85% usable AC capacity |
| Portable electric space heater (high) | 1,500 W resistive heat (Penn State EME 807) | 0.1 hours | Exceeds continuous AC rating (200 W); would drain 256 Wh in 0.1 hours |
