Assumption: 20 W constant. CableLabs measured Xfinity gateways (modem and router in one box) at 17.0 W and 23.6 W (XB7), 18.0 W (XB8), 29.0 W (XB10) ready-state.
| Scenario | Load | Hours |
|---|---|---|
| Router and modem, 20 W | 20 W | 20 hours |
| 29 W gateway (XB10) | 29 W | 15 hours |
| Router + 60 W laptop | 80 W | 7 hours |
| Math | 768 Wh × 0.9 × 0.85 ÷ (20 W + 10 W) = 20 hours | 20 hours |
