Our math
42 Wh per pound (768 Wh ÷ 18.2 lb). That is #65 of 184 portable power stations on Benchwatt with a listed weight. Higher means more stored energy for each pound you carry.
At its full rated 800 W, a full charge lasts about 49 min.
Runtime estimates
Hours = 768 Wh × 0.85 ÷ device watts. Typical draws; check your own device's label.
| Device | Draw | Runtime |
|---|---|---|
| Phone charging | 10 W | 65 h |
| Laptop | 60 W | 11 h |
| CPAP (no humidifier) | 40 W | 16 h |
| Mini fridge (average draw) | 60 W | 11 h |
| Full-size fridge (700 kWh/yr label) | 80 W | 8.2 h |
| TV | 100 W | 6.5 h |
| Space heater | 1,500 W | Exceeds rated output |
Estimates, not measurements. Fridges cycle on and off, so their average draw is well under their rated watts; heaters and kettles run near full power.
