Anker SOLIX C800 Plus Runtime Calculator

Quick answer: the Anker SOLIX C800 Plus stores 768 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 5.9 hours. Last source check: 2026-08-21. This is an estimate, not a guarantee.

Catalog notes (original English)

Surge output stays unknown because the exact manual publishes 1600W as Max Device(s) Power with SurgePad for primarily heat-generating loads, not universal motor-start headroom. Exact C800 Plus support keeps its 10.9kg weight distinct from the base C800.

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.

9h 48mEstimated runtime: 9h 48m

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

Conservative6h 8m
Estimated9h 48m
Optimistic12h 10m

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.

Source-Backed Next Steps

Planning notes

  • Capacity class: 768 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: 300 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: 10.9 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.
