Line-by-line math
- CPAP humidifier on: 268 Wh x 0.85 = 228 Wh / 53 W = 4.3 h = 0.5 nights.
- CPAP humidifier off: 268 Wh x 0.85 = 228 Wh / 30 W = 7.6 h = 0.9 nights.
- Compatible DC cable: 268 Wh x 0.92 = 247 Wh / 28 W = 8.8 h = 1.1 nights.
- Full-size refrigerator: 268 Wh x 0.85 = 228 Wh / 150 W = 1.5 h.
