What Bluetti Apex 300 + B500K + 500W 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) | 107.2 hours | About 4.5 days at 85% usable AC capacity |
| CPAP without heated humidifier | 11 W continuous (ResMed AirSense 10 Battery Guide) | 609.3 hours | About 76.2 eight-hour nights |
| Wi-Fi router + laptop computer | 60 W combined (10 W router + 50 W laptop, Penn State EME 807) | 111.7 hours | Continuous remote-work load at 85% usable AC capacity |
| Portable electric space heater (high) | 1,500 W resistive heat (Penn State EME 807) | 4.5 hours | Exceeds continuous AC rating (not stated); would drain 7,885 Wh in 4.5 hours |
Lifetime energy delivery and cost per lifetime kWh
Bluetti does not state a complete cycle count and capacity retention percentage pair on the official product specification page for the Apex 300 + B500K + 500W, so lifetime deliverable kilowatt-hours and cost per lifetime kWh are shown as not stated.
