Anker SOLIX 757 PowerHouse Runtime Calculator

Quick answer: the Anker SOLIX 757 PowerHouse stores 1,229 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 9.4 hours. Last source check: 2026-08-21. This is an estimate, not a guarantee.

Catalog notes (original English)

Surge remains unknown because neither exact source publishes a separate peak rating; the former continuous-ceiling duplicate is not startup headroom. The current US A1770 page's 1800W AC and 600W solar values are stored, while the exact support table still exposes older 1500W/300W values; confidence remains estimated until Anker reconciles the conflict.

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.

15h 40mEstimated runtime: 15h 40m

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

Conservative9h 48m
Estimated15h 40m
Optimistic19h 28m

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.

  • 85% conversion efficiency

  • 60 W average load from 1 load
  • 100% battery health

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: 1,229 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: 600 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: 19.9 kg. Check the complete carrying setup, cables and battery extensions before choosing this model for travel.
  • unknown: Surge output

Models: Anker SOLIX

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