Assumptions
These are calculation inputs, not lab-tested runtime claims.
- 1070 Wh nominal battery capacity
- AC inverter output path
- 85% conversion efficiency
- 15% reserve kept unused
- 40 W average load from 1 load
- 100% battery health
- 0% temperature loss
- Fixed station overhead unknown; not included
- This is an estimate. Real runtime changes with load, temperature, battery age, AC/DC output, and device behavior.
