Runtime plus compatibility
How long will a power station run your appliance?
Enter the battery, running load, starting load, and duty cycle. The calculator separates the energy estimate from the output checks that decide whether the appliance can start.
Live estimate
Your battery and load
Use the appliance nameplate or a plug-in power meter when possible. Peak output without a published duration is not a guarantee that every compressor or motor will start.
Estimated runtime
15.7 hours
- Average load
- 51.5 W
- Usable energy
- 811 Wh
- Formula
- usable Wh / average W
Compatibility first
How the current 1kWh records handle these inputs
A result can pass continuous output and still need a model-level surge check. That uncertainty stays visible instead of being turned into a false green check.

Check output
Match voltage, connector, continuous watts, and starting demand before trusting any hour estimate.
Expose losses
Usable capacity and conversion efficiency stay editable because product conditions and load paths vary.
Verify the appliance
Nameplate watts and a plug-in meter are more useful than a generic appliance estimate.
