Jackery Explorer 1500 Pro Runtime Calculator

Quick answer: the Jackery Explorer 1500 Pro stores 1,512 Wh and delivers up to 1,800 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 11.6 hours. Last source check: 2026-10-25. This is an estimate, not a guarantee.

Catalog notes (original English)

The JE-1500B 120V/60Hz manual and current support table agree on stored planning fields, with NMC chemistry attributed to the FAQ. The FAQ's 110V/18A AC row differs from the manual's 120V/15A table; the explicit manual defines this regional record, not its GB English language badge. The 1400W solar value is the explicit 24A dual-input ceiling; one input is capped at 700W, and DC load output is the separate 12V/10A car port. USB-C stores the highest single-port 100W rating. The unqualified 15W standby figure is not assigned as measured battery-side fixed overhead. The retired product URL redirects to the separate Explorer 1500 Ultra and is no longer active evidence.

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. r.jackery.net: Jackery Explorer 1500 Pro user manual — US 120V

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.

19h 17mEstimated runtime: 19h 17m. 12h 4m – 23h 56m. Within the tracked power limits; compatibility still needs checking

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

Conservative12h 4m
Estimated19h 17m
Optimistic23h 56m

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

  • 1512 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: 1,512 Wh. Size the battery for your measured average load and required hours, including reserve.
  • Tracked output: 1,800 W. Compare both running demand and startup demand before using any runtime estimate.
  • Solar input limit: 1,400 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: 17 kg. Check the complete carrying setup, cables and battery extensions before choosing this model for travel.

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