Line-by-line math
- CPAP humidifier on: 518 Wh x 0.85 = 440 Wh / 53 W = 8.3 h = 1.0 nights.
- CPAP humidifier off: 518 Wh x 0.85 = 440 Wh / 30 W = 14.7 h = 1.8 nights.
- Compatible DC cable: 518 Wh x 0.92 = 477 Wh / 28 W = 17.0 h = 2.1 nights.
- Full-size refrigerator: 518 Wh x 0.85 = 440 Wh / 150 W = 2.9 h.
