How this portable power station runtime calculator works
Usable watt-hours are divided by average watts to estimate runtime.
How to use it
- Battery capacity. Enter the value in Wh.
- Usable capacity. Enter the value in %.
- Average load. Enter the value in W.
- Request the result. Add your email, then select “Email & show my result.”
What to do with the number
Inverter losses, battery management limits and changing device loads can reduce actual runtime. Use the measured running watts of the connected devices rather than their maximum labels.
Planning estimate
Use this result as a starting point, not a guarantee. Product specifications, site conditions, manufacturer guidance, local codes, taxes, labor, tolerances, and rounding can change the real requirement or cost.
