High conversion efficiency: Made of monocrystalline silicon solar cells, the solar panels use multi-layer cell technology to convert natural sunlight into usable energy. With up to 20% high conversion efficiency, the solar panels perform better than other normal panels. Two fast charging outputs: Equipped with QC3.0 24W and DC 18V/6A outputs, the solar panel is universally compatible with phones, power banks, and other mobile devices. The DC cable and three adapters allow you to charge the panel, power station, and solar generator. Includes carabiner and easy installation: The solar panel charger is equipped with 2 eyelet holes and is super easy to hang on your backpack. We recommend placing the panel at a 45-degree angle to the sun, which is the optimal placement for the panel to fully capture sunlight and convert it into usable energy. SPACE-SAVING AND LONGER LIFESPAN: Lightweight, compact, and foldable design with dimensions of 185 x 115 x 20 mm, super space-saving and easy to store. The solar panel charger is made of high-quality monocrystalline silicon solar cells with high-transmittance ETFE film and 600D water-repellent fabrics. Everything is designed for high durability and longer lifespan. For RV camping off-grid: The 30W solar panel with a portable power station would be an excellent preparation for power outages, blackouts, and off-grid solar panels. With solar energy in hand, it's worth a try.
