Capacity-first planning

What can a 2,000 Wh power station run?

Compare ten common loads before adjusting the calculator for your exact device, output path, battery condition, and reserve.

Runtime by device

Each row uses the scenario's sourced planning load and the site's shared runtime engine.

Assumptions: scenario-specific AC efficiency and duty cycle, 10% reserve, new battery, no temperature loss, and no fixed station idle draw.

These are calculated planning estimates, not measured runtimes. Low-power loads can be more sensitive to station idle draw, and runtime does not prove AC output or startup-surge compatibility.

For CPAP or other medical-comfort use, confirm the exact device and battery guidance with the manufacturer. Do not rely on this table as a critical backup plan.
