NUE SunCase 605 Runtime Calculator

Quick answer: the NUE SunCase 605 stores 540 Wh and delivers up to 600 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 4.1 hours. Last source check: 2026-08-27. This is an estimate, not a guarantee.

Catalog notes (original English)

NUE has no reachable first-party storefront for this model, so this record uses a retailer-published copy of the manufacturer specification sheet and stays at estimated confidence. Surge and USB-C ceilings stay unknown because the sheet publishes neither.

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 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.

6h 53m

This setup may cover a partial outage or single overnight session. Add capacity for more margin.

Conservative4h 19m

Estimated6h 53m

Optimistic8h 33m

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: 540 Wh. Size the battery for your measured average load and required hours, including reserve.
Tracked output: 600 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: 7.98 kg. Check the complete carrying setup, cables and battery extensions before choosing this model for travel.
unknown: Surge output, USB-C output

Models: NUE

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