Sourced comparison tool

Compare portable power stations

Put two to four systems side by side and estimate runtime for your own continuous load.

Compare capacity, output and practical fit

Choose models from the 15-product database. The table separates stored energy from power output, checks your required voltage and names verified compatible expansion batteries. Only base US battery configurations are screened; more batteries do not automatically add inverter power. Compatibility appears as “Not verified” until a manufacturer source confirms it. Price is excluded until it can be monitored reliably.

How the runtime estimate works

Estimated AC runtime = rated capacity x 85% available capacity (15% held back) x 90% inverter efficiency divided by your continuous load. This is a comparison estimate, not a tested result. It assumes no separate idle draw and only reports a screened runtime when the selected voltage and supplied starting demand fit verified ratings. With starting demand left blank, runtime is an energy estimate only, not a supported-load verdict. Actual runtime changes with temperature, battery age, inverter self-consumption and appliance cycling.

i
Capacity does not prove compatibility. Confirm outlet voltage, continuous output and motor surge against the appliance and manufacturer manuals. Choose the voltage your load actually needs. A known total output does not prove a rating at both voltages, or at each socket or split-phase leg. This tool screens battery operation only: AC charging, bypass/UPS, simultaneous mixed-voltage loads and installation compatibility are not evaluated. Unknown limits never earn a pass.

Data method and limits

Specifications come from primary manufacturer pages and carry a checked date. Null values appear as "Not verified", never zero. Research status means the record is sourced but has no dedicated product page yet. See the editorial method and public JSON dataset. The compiled dataset is available under CC BY 4.0 with SolarStateData attribution; manufacturer names and trademarks remain their owners' property.
