Mobile detailing power station runtime calculator

Estimate portable power-station runtime, usable AC energy, complete detailing jobs per charge and whether entered continuous and start-up loads fit the output ratings.

Use the manufacturer's watt-hour capacity and output ratings. For operating watts, enter the average combined load while the station is actually supplying equipment—not every appliance owned.

Reduce this if the manufacturer publishes a smaller usable capacity.

The actual charge rate may taper and may be limited by the supply.

The entered output ratings cover the modelled load, but sockets, earth arrangements, duty cycle, temperature, battery ageing and manufacturer compatibility still need checking.

Compare only after the numbers fit.

Filter candidates by continuous output, start-up capability, usable watt-hours, recharge time, weight and warranty—not the largest headline capacity.

Your numbers fit a battery station?

Compare six exact 1–2.3 kWh models by normal output, published start or uplift evidence, nameplate energy, weight, sockets and recharge.

Planning a direct 12V auxiliary system instead?

Keep that separate from AC power-station capacity and model the measured DC current, usable amp-hours and recharge loop.
