What it runs, and for how long
Estimates use our published formula — capacity × 0.85 ÷ load, duty cycle applied to cycling loads, and a start check against the surge rating (methodology). Loads that fail the start check are marked, not given a fake runtime.

Goal Zero Yeti 1500X questions
How long will the Goal Zero Yeti 1500X run a refrigerator?
About 4.6 hours for a typical fridge at a 40% compressor duty cycle (700 W nameplate draw while running), using our standard formula: 1,516 Wh × 0.85 ÷ 280 W average. That is the duty-cycled figure; the same station runs the fridge for about 1.8 hours if the compressor never cycles off.
How long will it run a CPAP?
About 32.2 hours at 40 W — a typical CPAP without a heated humidifier — or roughly 4.0 nights at 8 hours a night. With a heated humidifier (~90 W) expect about 14.3 hours. That's device runtime math only; see the CPAP calculator for your device's actual wattage.
How long does it take to recharge from solar?
With 400 W of panels, the Goal Zero Yeti 1500X needs about 4.9 hours of full sun for a full charge after the 0.78 real-world derate. Try other panel sizes in the solar charging calculator.
