ALLPOWERS R4000 V2 Runtime Calculator

Quick answer: the ALLPOWERS R4000 V2 stores 2,880 Wh and delivers up to 4,000 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 22.0 hours. Last source check: 2026-08-27. This is an estimate, not a guarantee.

Catalog notes (original English)

This is a separate SKU from the catalogued 3456Wh R4000. Chemistry, surge, USB-C, DC, solar input and weight stay unknown because the listing publishes no specification table for them.

Regional source note Some specs are cross-checked against official regional pages. Regional SKUs can differ; verify the manufacturer page for your market before purchase or emergency planning. uk.iallpowers.com: ALLPOWERS R4000 V2 official UK regional product page

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.

1d 12hEstimated runtime: 1d 12h

This setup has comfortable headroom for overnight use, assuming the wattage estimate is realistic.

Conservative22h 59m
Estimated1d 12h
Optimistic1d 21h

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

  • 2880 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: 2,880 Wh. Size the battery for your measured average load and required hours, including reserve.
  • Tracked output: 4,000 W. Compare both running demand and startup demand before using any runtime estimate.
  • Solar input limit: unknown. 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: unknown. Check the complete carrying setup, cables and battery extensions before choosing this model for travel.
  • unknown: Battery chemistry, Surge output, DC output, USB-C output, Solar input, Weight

Models: ALLPOWERS

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