Anker SOLIX C800 Runtime Calculator
Quick answer: the Anker SOLIX C800 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. The exact C800 manual's 10.5kg value takes precedence over the 10.9kg value on the shared C800/C800 Plus page. A sold-out storefront state is not treated as discontinued lifecycle evidence.
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.

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.

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.

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: 10.5 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.
