Powkey R1000 Runtime Calculator
Quick answer: the Powkey R1000 stores 740 Wh and delivers up to 1,000 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 5.7 hours. Last source check: 2026-08-27. This is an estimate, not a guarantee.

Catalog notes (original English)
Surge stays unknown because the table publishes no peak AC figure. USB-C, DC and solar ceilings stay unknown: the table publishes PD voltage and current profiles without watt limits.
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.

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.

Optimistic11h 43m
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: 740 Wh. Size the battery for your measured average load and required hours, including reserve.
- Tracked output: 1,000 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: 8.3 kg. Check the complete carrying setup, cables and battery extensions before choosing this model for travel.
- unknown: Surge output, DC output, USB-C output, Solar input
Models: Powkey
Compare nearby capacity records from the same brand, then check output, weight and missing fields. A larger battery does not establish device compatibility.
