For an appliance plugged into an AC outlet, account for the station’s reserve and inverter losses. Then separately check that the station can supply the appliance’s running watts and startup surge. The result is a planning estimate, not a guaranteed runtime.
Use the right energy and power figures
A portable power station’s capacity is expressed in watt-hours (Wh), a measure of energy. An appliance’s draw is expressed in watts (W), a measure of the rate it uses energy. Dividing watt-hours by watts gives hours, provided the energy figure represents what can reach the appliance.

For an AC appliance, use this estimate:

Choose an estimate method and state its assumptions
A quick rule of thumb
Jackery Support’s July 2, 2026 guidance suggests multiplying rated capacity by 0.8, then dividing by appliance watts. That is a convenient approximation for stable loads, not a universal specification or tested result for every power station. Jackery cautions that actual use and environmental conditions affect runtime, and that the shortcut is not suitable for variable or high-startup loads such as air conditioners, refrigerators, and freezers. Jackery Support’s runtime guidance.
A more explicit estimate
When you have defensible assumptions for usable capacity and inverter efficiency, keep them separate in the calculation. PowerLab’s calculator uses 90% usable capacity and 88% inverter efficiency as an illustrative assumption set: a nominal 1,000 Wh station would deliver an estimated 792 Wh to AC appliances under those assumptions. These are calculator assumptions, not measured performance for a particular model. PowerLab’s calculator and assumptions.

Worked example: a steady 60 W appliance
For a nominal 1,000 Wh station and a steady 60 W load, the two approaches produce nearly the same estimate, but for different stated assumptions:
| Method | Calculation | Estimated runtime |
|---|---|---|
| Jackery’s quick approximation | (1,000 Wh × 0.8) ÷ 60 W | About 13.3 hours; a rule-of-thumb estimate, not a product test. |
| PowerLab’s illustrative assumptions | (1,000 Wh × 0.90 × 0.88) ÷ 60 W | 13.2 hours; based on the calculator’s assumed usable capacity and inverter efficiency, not a product test. |
For a different station, replace 1,000 Wh with its rated capacity and use a supported usable-energy estimate. For another appliance, use its average draw in watts. These calculations assume the load is steady; actual runtime can differ with battery condition, temperature, inverter behavior, and how the appliance operates.

Find a realistic appliance wattage
Start with the appliance’s label or manual, but check what the listed number means. A maximum or rated draw may not reflect the average power used over the time you need to run it.
- For a steady load: use its running draw if the appliance operates continuously at roughly that level.
- For a cycling load: estimate average draw across its on/off cycle, rather than treating its peak or on-cycle rating as continuous. Refrigerators, for example, cycle instead of drawing the same power constantly.
- For a compatible plug-in appliance: a plug-in electricity usage meter can help measure its actual outlet draw. This method does not cover every appliance, such as hardwired equipment, and it does not replace checking startup demand.
PowerLab’s calculator treats average connected load in terms of running watts and duty cycle. Treat a calculation based on an estimated cycle or measured draw as a planning figure, not a promise of how long the station will last.

Check that the station can run the appliance at all
Capacity estimates duration; output ratings determine whether the station can power the appliance. Check all three of these before relying on a runtime result:
- Continuous output: compare the appliance’s running watts with the station’s continuous AC output rating.
- Startup or peak demand: compare the appliance’s startup watts with the station’s surge or peak output rating. Some appliances briefly need more power to start than they use while running.
- Connection and output mode: confirm that the station’s outlet and output mode match the appliance’s requirements.
A station may have enough watt-hours for a long theoretical runtime but still be unable to start or sustain a load that exceeds its output limits. PowerLab describes the running-watts and continuous-rating check alongside the startup-surge and peak-limit check; Jackery also warns that its simplified runtime calculation is unsuitable for loads with high startup demand.

Why actual runtime can differ
A formula estimates runtime from the figures you provide; it does not account precisely for every condition. The result can change with the usable energy retained by the station, conversion losses, temperature, battery age or condition, inverter behavior, and the appliance’s changing load. WhatPowerFor identifies reserve, inverter losses, temperature, and age as factors, but its general guidance should not be treated as a specification for a particular model. WhatPowerFor’s runtime calculator guidance.
For a better estimate, prioritize the station’s own published usable-energy or runtime information and a realistic average appliance draw. If either input is an assumption, keep that qualification alongside the calculated result.
