BougeRV Fort 1500 Runtime Calculator

Quick answer: the BougeRV Fort 1500 stores 1,456 Wh and delivers up to 2,200 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 11.1 hours. Last source check: 2026-08-21. This is an estimate, not a guarantee.

Catalog notes (original English)

Neither the exact product table nor the ISE164 manual publishes a separate AC surge figure, so surge remains unknown. The manual identifies the cigarette socket plus two DC5521 outputs as a 140W maximum combined 12V path.

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.

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.

18h 34mEstimated runtime: 18h 34m

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

Conservative11h 37m
Estimated18h 34m
Optimistic23h 3m

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

  • 1456 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: 1,456 Wh. Size the battery for your measured average load and required hours, including reserve.
  • Tracked output: 2,200 W. Compare both running demand and startup demand before using any runtime estimate.
  • Solar input limit: 400 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: 18 kg. Check the complete carrying setup, cables and battery extensions before choosing this model for travel.
  • unknown: Surge output

Models: BougeRV

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