Line-by-line math
- CPAP humidifier on: 3600 Wh x 0.85 = 3060 Wh / 53 W = 57.7 h = 7.2 nights.
- CPAP humidifier off: 3600 Wh x 0.85 = 3060 Wh / 30 W = 102.0 h = 12.8 nights.
- Compatible DC cable: 3600 Wh x 0.92 = 3312 Wh / 28 W = 118.3 h = 14.8 nights.
- Full-size refrigerator: 3600 Wh x 0.85 = 3060 Wh / 150 W = 20.4 h.
