Sungzu SKA100 Runtime Calculator

Quick answer: the Sungzu SKA100 stores 99.9 Wh. Its continuous AC rating is not confirmed by a usable source, so this record keeps the field unknown rather than guessing — check the sources below before planning AC loads. Last source check: 2026-08-27. This is an estimate, not a guarantee.

Catalog notes (original English)

The SKA100 is a DC-only unit with no AC inverter, so AC output stays unknown rather than being recorded as zero. Sungzu quotes the solar input only as an 18-30V 3A current limit, which does not resolve to a single wattage, so solar input stays unknown. Sungzu highlights that the sub-100Wh pack is the one model in the range that can be carried onto an aircraft.

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

Output or startup compatibility is not established

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.

Output or startup compatibility is not established

Conservative48m

Estimated1h 17m

Optimistic1h 35m

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.

Output or startup compatibility is not established
The selected station output rating is unknown, so running-load compatibility is not verified.

Planning notes

Capacity class: 99.9 Wh. Size the battery for your measured average load and required hours, including reserve.
Tracked output: unknown. 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: AC output, Surge output, Solar input, Weight

Models: Sungzu

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