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.

Jackery Explorer 300 Plus questions

How long will the Jackery Explorer 300 Plus run a refrigerator?

No — not a full-size fridge by Generac's worksheet figures. A fridge draws 700 W while its compressor runs, above this model's 300 W continuous rating, so it cannot run one at all. Smaller loads are fine.

How long will it run a CPAP?

About 6.1 hours at 40 W — a typical CPAP without a heated humidifier — or roughly 0.8 nights at 8 hours a night. With a heated humidifier (~90 W) expect about 2.7 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 Jackery Explorer 300 Plus needs about 3.7 hours of full sun for a full charge after the 0.78 real-world derate — capped by the station's 100 W maximum solar input. Try other panel sizes in the solar charging calculator.
