Line-by-line math
- CPAP humidifier on: 1536 Wh x 0.85 = 1306 Wh / 53 W = 24.6 h = 3.1 nights.
- CPAP humidifier off: 1536 Wh x 0.85 = 1306 Wh / 30 W = 43.5 h = 5.4 nights.
- Compatible DC cable: 1536 Wh x 0.92 = 1413 Wh / 28 W = 50.5 h = 6.3 nights.
- Full-size refrigerator: 1536 Wh x 0.85 = 1306 Wh / 150 W = 8.7 h.
