Goal Zero Yeti 200X Runtime Calculator
Quick answer: the Goal Zero Yeti 200X stores 187 Wh and delivers up to 120 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 1.4 hours. Last source check: 2026-08-21. This is an estimate, not a guarantee.

Catalog notes (original English)
The US storefront explicitly labels the model No Longer Available. DC output stores the highest listed 120W 12V path; solar input stores the 100W 8mm charging-port ceiling rather than a panel rating.
Lifecycle note: This label describes availability in the cited region only. It does not imply that another model is universally better, compatible, or an official replacement. Open 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.

Conservative1h 30m
Estimated2h 23m
Optimistic2h 58m
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: 187 Wh. Size the battery for your measured average load and required hours, including reserve.
- Tracked output: 120 W. Compare both running demand and startup demand before using any runtime estimate.
- Solar input limit: 100 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: 2.27 kg. Check the complete carrying setup, cables and battery extensions before choosing this model for travel.
- unknown: —
Models: Goal Zero
Compare nearby capacity records from the same brand, then check output, weight and missing fields. A larger battery does not establish device compatibility.
