Key features
- 【BIG POWER, STILL PORTABLE】 Folds to 19.3×37.4×1.1in and weighs only 15.2lb, so this 300W panel packs serious energy yet remains slim and easy to move, mount, or store for RVs, vans, boats, and backup use.
- 【SEPARATE CONTROLLER FOR SAFER CHARGING】 Equipped with a standalone PWM controller that protects your 12V system from reverse polarity, overcharge, overload, and short-circuit—and can be replaced or upgraded later if needed.
- 【LONG REACH FOR FLEXIBLE SETUP】 Includes a 9.85ft (3m) cable, allowing you to place the panel in full sunlight while keeping the controller or power station safely shaded for cooler, safer operation.
- 【KNOW YOUR POWER STATION’S LIMITS】 Some power stations restrict solar input (often 100-200W). Even under full sun, a 300W panel cannot exceed your unit’s own cap—this is normal design, not a defect. Please check your model or message us for confirmation before ordering.
- 【USB CHARGING WHEN YOU NEED IT】 When connected to a 12V battery, the dual USB ports provide stable power for phones, lights, and small devices. Even without a battery, they can still work in sunlight for emergency top-ups, though current may fluctuate.
- 【MONOCRYSTALLINE EFFICIENCY, BUILT FOR OUTDOORS】 High-grade mono cells deliver better conversion efficiency and reduce mismatch loss. The panel surface is weather-resistant, but avoid leaving the fabric case in heavy rain or strong sun for days to extend life.
- 【COMPLETE BUNDLE READY TO GO】 Includes the 300W foldable panel, separate controller, SAE/XT60/Alligator clips, DC5521/5525/35135/6440 adapters, 9.85ft cable, storage bag, and manual—a one-stop kit for camping, RVing, or emergency backup.
