The Checks, One by One
| Check | Result | Detail |
|---|---|---|
| Running watts | ✅ pass | 500W continuous output covers the appliance's 10W running draw, leaving 490W of headroom. |
| Runtime | ℹ️ info | 499Wh of battery at a 75% AC-inverter efficiency factor gives roughly 37.4 hours of continuous running at 10W. |
Side by Side
| Spec | Goal Zero Yeti 500 Core | Wi-Fi Router needs |
|---|---|---|
| Continuous output | 500W | 10W |
| Startup surge | 1000W | No meaningful surge |

Methodology
Verdict computed from this project's verified entity data using the same gates as its use-case scoring: waveform requirement first (an unconfirmed inverter type fails rather than passing), then continuous watts, then startup surge, then runtime at a 75% AC-inverter efficiency factor.
