NEWSMY P72 Runtime Calculator

Quick answer: the NEWSMY P72 stores 270 Wh and delivers up to 268 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 2.1 hours. Last source check: 2026-08-27. This is an estimate, not a guarantee.

Catalog notes (original English)

NEWSMY has no reachable English first-party storefront for this model, so this record uses a retailer-published copy of the manufacturer specification table and stays at estimated confidence. Chemistry, surge and DC ceilings stay unknown because the table publishes none.

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.

3h 27m

This setup is tight. Reduce load, use DC where possible, or choose a larger station.

Conservative2h 9m

Estimated3h 27m

Optimistic4h 16m

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: 270 Wh. Size the battery for your measured average load and required hours, including reserve.
Tracked output: 268 W. Compare both running demand and startup demand before using any runtime estimate.
Solar input limit: 100 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: 2.3 kg. Check the complete carrying setup, cables and battery extensions before choosing this model for travel.
unknown: Battery chemistry, Surge output, DC output

Models: NEWSMY

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