PowerArQ PowerArQ 3 Runtime Calculator

Quick answer: the PowerArQ PowerArQ 3 stores 555 Wh and delivers up to 500 W of continuous AC power. Under this site's planning assumptions (85% inverter efficiency, 10% reserve), a steady 100 W AC load runs for roughly 4.2 hours. Last source check: 2026-08-27. This is an estimate, not a guarantee.

Catalog notes (original English)

Weight stores the published body-plus-battery figure; the same table lists the removable battery alone at about 3.77kg. DC stays unknown because the table publishes a 12V/10A profile without a watt limit, and chemistry stays unknown because the table has no chemistry row. PowerArQ is a Japan-market brand and this record follows its published 100V configuration; the official product page is in Japanese.

Runtime estimate

Formula starting points use each scenario’s default watts, duty cycle and output path, with 10% reserve or 15% for CPAP. Linked detail pages use the same inputs. Hours apply only if the device can run and start; they are not measured runtimes.

Runtime calculator

Runtime is conditional on successful startup, compatible voltage/connectors and sufficient output. Verify the actual device setup before relying on these hours.

Estimated runtime

Within the tracked power limits; compatibility still needs checking

This is an estimate. Real runtime changes with load, temperature, battery age, AC/DC output, and device behavior. Runtime is conditional on successful startup, compatible voltage/connectors and sufficient output. Verify the actual device setup before relying on these hours.

7h 5mEstimated runtime: 7h 5m

This setup may cover a partial outage or single overnight session. Add capacity for more margin.

Conservative4h 26m
Estimated7h 5m
Optimistic8h 47m

These are calculated sensitivity cases, not a statistical confidence interval. Conservative uses lower efficiency and battery health, more reserve/temperature loss and higher load; optimistic changes these assumptions in the opposite direction.

Assumptions

  • 555 Wh nominal battery capacity
  • AC inverter output path
  • 85% conversion efficiency
  • 10% reserve kept unused
  • 60 W average load from 1 load
  • 100% battery health
  • 0% temperature loss
  • Fixed station overhead unknown; not included

Warnings

  • This is an estimate. Real runtime changes with load, temperature, battery age, AC/DC output, and device behavior. Runtime is conditional on successful startup, compatible voltage/connectors and sufficient output. Verify the actual device setup before relying on these hours.
  • Within the tracked power limits; compatibility still needs checking

Planning notes

  • Capacity class: 555 Wh. Size the battery for your measured average load and required hours, including reserve.
  • Tracked output: 500 W. Compare both running demand and startup demand before using any runtime estimate.
  • Solar input limit: 200 W. Actual refill depends on panel voltage/current compatibility, sunlight, angle and charging losses.

Known data gaps

  • Unverified or missing specifications remain visible. The confidence label describes the station record, not a tested runtime or approval for emergency use.
  • Weight: 7.9 kg. Check the complete carrying setup, cables and battery extensions before choosing this model for travel.
  • unknown: Battery chemistry, DC output

Models: PowerArQ

Compare nearby capacity records from the same brand, then check output, weight and missing fields. A larger battery does not establish device compatibility.
