Runtime estimates

| Device | Draw | Runtime |
|---|---|---|
| Phone charging | 10 W | 44 h |
| Laptop | 60 W | 7.4 h |
| CPAP (no humidifier) | 40 W | 11 h |
| Mini fridge (average draw) | 60 W | 7.4 h |
| Full-size fridge (700 kWh/yr label) | 80 W | 5.5 h |
| TV | 100 W | 4.4 h |

Estimates, not measurements. Fridges cycle on and off, so their average draw is well under their rated watts; heaters and kettles run near full power.
