|---|---|---|
| 500Wh Station | 1 – 2 Full Nights (8-14 Hours) | Light emergency & mobile survival |
| 1000Wh Station | 3 – 4 Full Nights (24-30 Hours) | Recommended for short rolling blackouts |
| 2000Wh Station | 7+ Full Nights | Full multi-day storm security |
Technical Sizing Analysis
Using the 12V DC car outlet adapter instead of the standard 110V AC plug increases battery efficiency by up to 35%, because it bypasses the internal DC-to-AC inverter losses. Turning off the heated humidifier and heated tubing significantly lowers wattage from 90W down to just 35W.
