【TRAVEL LIGHT, POWER ANYWHERE】 Weighing only 15.3lb and folding to 20*38*1.1in, this 300W panel is slim yet powerful, easy to carry, mount, or store—perfect for RVs, campers, trailers, and emergency backup use.
【LONG REACH FOR FLEXIBLE SETUP】 A 9.84ft (3m) cable allows you to position the panel in direct sunlight while keeping the controller or power station shaded, making installation safer and more convenient.
【SEPARATE CONTROLLER FOR SAFE CHARGING】 Comes with a standalone PWM controller that safeguards your 12V system from reverse polarity, overcharge, overload, and short-circuit—safe to use and simple to replace or upgrade later.
【CHECK YOUR POWER STATION’S INPUT LIMIT】 Some power stations cap input (e.g. 150-200W max). Even under full sun, this 300W panel cannot exceed that cap—this is normal system design, not a defect. Please verify your specs or contact us before purchase.
【USB PORTS FOR ESSENTIAL DEVICES】 When connected to a 12V battery, the dual USB ports provide steady charging for phones, lamps, and small gear. They can also deliver emergency power under sunlight without a battery, though current may vary.
【HIGH-EFFICIENCY MONOCRYSTALLINE CELLS, OUTDOOR-READY】 Built with premium mono cells for higher conversion efficiency and reduced mismatch loss. The panel surface withstands sun and splashes, but avoid leaving the fabric case in heavy rain or strong sun for extended periods.
【ALL-IN-ONE KIT, READY TO GO】 Includes 300W foldable panel, standalone controller, SAE/XT60/alligator clips, 4 DC adapters (3.5×1.35mm / 5.5×2.1mm / 5.5×2.5mm / 8.0mm), 9.8ft cable, storage bag, and manual—everything you need for quick setup right out of the box.
