Line-by-line math
- CPAP humidifier on: 1433 Wh x 0.85 = 1218 Wh / 53 W = 23.0 h = 2.9 nights.
- CPAP humidifier off: 1433 Wh x 0.85 = 1218 Wh / 30 W = 40.6 h = 5.1 nights.
- Compatible DC cable: 1433 Wh x 0.92 = 1318 Wh / 28 W = 47.1 h = 5.9 nights.
- Full-size refrigerator: 1433 Wh x 0.85 = 1218 Wh / 150 W = 8.1 h.
