Real-World Runtime by Battery Capacity
| Battery Size | Estimated Continuous Runtime | Suitability Assessment |
|---|---|---|
| 500Wh Station | 20 Minutes (Not Practical) | Light emergency & mobile survival |
| 1000Wh Station | 45 Mins (High) / 1.3 Hours (Low) | Recommended for short rolling blackouts |
| 2000Wh Station | 1.5 Hours (High) / 2.8 Hours (Low setting) | Full multi-day storm security |
Technical Sizing Analysis
Electric resistance heating is one of the heaviest battery drains. To survive winter freezes, we strongly advise using an electric heated blanket (consuming only 60W) instead of heating the entire room with a 1500W space heater.
