Line-by-line math
- CPAP humidifier on: 3840 Wh x 0.85 = 3264 Wh / 53 W = 61.6 h = 7.7 nights.
- CPAP humidifier off: 3840 Wh x 0.85 = 3264 Wh / 30 W = 108.8 h = 13.6 nights.
- Compatible DC cable: 3840 Wh x 0.92 = 3533 Wh / 28 W = 126.2 h = 15.8 nights.
- Full-size refrigerator: 3840 Wh x 0.85 = 3264 Wh / 150 W = 21.8 h.
