【ETFE Material, 24% Solar Conversion Efficiency】Using monocrystalline solar cells covered with highly transparent ETFE material, the solar energy conversion rate reaches 24%. Compared to solar panels made of conventional PET/SEWN material, ETFE is more stable and has longer lifespan. It efficiently converts sunlight into electricity and can provide environmentally friendly energy. 【USB-C, PD18W, QC3.0 Fast Charging】3 USB Ports support three output methods, USB-C PD18W, QC3.0 12V/2A(Max), USB-A 5V/2.4A. Each port has a built-in smart IC and auto-resume charging function, which can automatically and quickly recognize your device and charge it with the appropriate current to speed up the charging process. It also has a built-in protection system to ensure the charging safety of solar chargers and devices. 【IPX5 Waterproof/Dustproof/Durability】ETFE thermoplastic resin is used, which is definitely recommended for outdoor activities such as hiking and camping. The high-density ETFE surface makes it highly waterproof/fireproof/dustproof, while also has self-cleaning function. IPX5 waterproof level, protect your solar powered charger and your devices from occasional rain or wet fog, but keep it away from water when you have some devices on charge. 【Highly Compact/Foldable/Portable】Compact size (28*19.7cm folded) and stainless-steel eye-holes on each corner allow easy attachment to backpacks, trees, or tents. Lightweight (980g) and ultra-thin design (3.5cm folded or 0.5cm opened) make it ideal for outdoor activities and long treks. 【Zipper Storage Bag】The solar charger storage bag uses zipper. You can place your smartphone orpower bank in the zip pocket while charging, keep it safe and clean, without worrying about the device falling while hanging the solar panel., Weight: 1.9621141318 pounds, Manufacturer: ELECAENTA
