Litheli B218 Runtime Calculator
Quick answer: the Litheli B218 stores 216 Wh and delivers up to 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 1.7 hours. Last source check: 2026-08-27. This is an estimate, not a guarantee.

Catalog notes (original English)
Weight stays unknown because the page quotes 8.8 lbs, 2.7kg and a 3.99kg shipping figure that do not agree. Chemistry, surge and solar input are not published.
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

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.
2h 45mEstimated runtime: 2h 45mThis setup is tight. Reduce load, use DC where possible, or choose a larger station.
Conservative1h 43m
Estimated2h 45m
Optimistic3h 25m
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: 216 Wh. Size the battery for your measured average load and required hours, including reserve.
- Tracked output: 200 W. Compare both running demand and startup demand before using any runtime estimate.
- Solar input limit: unknown. 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: unknown. Check the complete carrying setup, cables and battery extensions before choosing this model for travel.
- unknown: Battery chemistry, Surge output, Solar input, Weight
Models: Litheli
Compare nearby capacity records from the same brand, then check output, weight and missing fields. A larger battery does not establish device compatibility.
