Companion Rover 1300 Runtime Calculator
Quick answer: the Companion Rover 1300 stores 1,344 Wh and delivers up to 1,200 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 10.3 hours. Last source check: 2026-08-27. This is an estimate, not a guarantee.

Catalog notes (original English)
The Rover 1300 shares the Rover 1000 inverter and adds a larger pack. The 1800W Power Boost figure is a short-duration assist mode rather than a continuous rating, so this record keeps the published 1200W continuous inverter rating. Companion is an Australian outdoor brand whose storefront is served from the regional oztrail.com.au domain (companionbrands.com.au redirects there), so specifications are quoted for the 240V Australian market SKU. Companion does not publish port-level DC or USB-C ceilings or a product weight for the Rover range, so those fields stay unknown and the record remains at estimated confidence.
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. oztrail.com.au: Companion official Rover 1300 Power Station 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.

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.

Optimistic21h 17m
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.

Planning notes
- Capacity class: 1,344 Wh. Size the battery for your measured average load and required hours, including reserve.
- Tracked output: 1,200 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: unknown. Check the complete carrying setup, cables and battery extensions before choosing this model for travel.
- unknown: DC output, USB-C output, Weight
Models: Companion
Compare nearby capacity records from the same brand, then check output, weight and missing fields. A larger battery does not establish device compatibility.
