Solar input tracks the 8mm charge port limit; US and EU surge ratings should be reconciled before comparison claims.
Regional source note: Some specs are cross-checked against official regional pages (goalzero.eu: Goal Zero Yeti 500X specifications). Regional SKUs can differ; verify the manufacturer page for your market before purchase or emergency planning.
Runtime Starting Points
These are formula estimates using the tracked capacity, a 10% reserve, and each scenario's default wattage and duty cycle. They are planning starters, not measured runtimes.

Good fit when
- Capacity is best suited to lighter essentials such as routers, laptops, CPAP planning, lights, and smaller camping loads.
- Tracked AC output is 300 W, so high-draw appliances and tools need careful filtering.
- USB-C output is tracked at laptop-class power, useful for direct DC charging when the device supports it.
- Tracked solar input is 150 W before panel, weather, angle, and controller losses.
Watch out for
- Surge output is tracked, but device startup behavior should still be checked against the actual load.
