Our math
43 Wh per pound (5,120 Wh ÷ 119 lb). That is #62 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 3,600 W, a full charge lasts about 1.2 h.
Runtime estimates
Hours = 5,120 Wh × 0.85 ÷ device watts. Typical draws; check your own device's label.
| Device | Draw | Runtime |
|---|---|---|
| Phone charging | 10 W | 435 h |
| Laptop | 60 W | 73 h |
| CPAP (no humidifier) | 40 W | 109 h |
| Mini fridge (average draw) | 60 W | 73 h |
| Full-size fridge (700 kWh/yr label) | 80 W | 54 h |
| TV | 100 W | 44 h |
| Space heater | 1,500 W | 2.9 h |
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.
