Why A Range, Not One Magic Number
Runtime is not just battery size divided by device watts. Whether the product is sold as a portable power station or a solar generator, AC inverter losses, duty cycle, battery health, reserve, and cold weather can all change the number, so the calculator leads with a usable range.
Simple formula
Runtime hours = usable battery Wh / average device W.
Usable watt-hours
Usable Wh = nominal Wh x efficiency x reserve factor x battery health x temperature factor.
Inverter efficiency
AC output runs through an inverter, so part of the pack becomes heat. A DC or USB-C path keeps more of the stored energy for the device.
Duty cycle
Compressors and pumps only draw full watts part of the time. A load that runs half of each hour averages roughly half its nameplate draw.
Scenario loads
Fridges cycle, CPAP humidifiers add heat load, and Starlink draw changes by kit and power path.
Battery health and cold
Cells deliver fewer usable watt-hours as they age and in cold weather, so an older pack outdoors will not match its first-season numbers.
Why a range
The estimate is the center point. Conservative and optimistic outputs show what happens when efficiency, reserve, temperature, and load move against or in favor of the setup.
1,024 Wh example
At 85% AC efficiency with 10% reserve, a 1,024 Wh station leaves about 783 Wh usable. A steady 60 W load is roughly 13 hours before real-world losses change the result.
Results are estimates. Real runtime depends on load, temperature, battery condition, AC/DC output, surge behavior, and device settings.

FAQ
Short answers for common runtime planning questions.
How do you calculate portable power station runtime?
Use usable watt-hours divided by average load watts. For AC loads, a practical first-pass formula is battery Wh x efficiency x reserve factor divided by device watts.
Why is real runtime lower than the label capacity?
Battery label capacity is nominal. Inverter losses, DC conversion losses, reserve settings, cold weather, battery age, and changing device loads all reduce real runtime.
What efficiency should I use for AC devices?
Use 80% to 90% for most AC inverter loads unless you have measured data. The default calculator value is 85%.
What efficiency should I use for DC devices?
DC loads can often do better than AC because the inverter stays off. Use 88% to 95% only when the voltage path is appropriate and the device is stable.
Can a power station run a refrigerator overnight?
Often yes, but the answer depends on battery Wh, fridge running watts, compressor duty cycle, room temperature, and startup surge. Always check surge capability.
