Why choose the EcoFlow Portable Solar Panel 28W This model focuses on portability first. At around 0.6 kg, it is easy to pack and carry, while the foldable format makes it easier to store in a backpack or gear bag. For users who need light outdoor charging rather than a large solar setup, the 28W output offers a compact balance of size and usefulness. Lightweight and foldable for travel and outdoor use Direct-to-device charging through built-in USB outputs High-efficiency N-Type TOPCon monocrystalline solar cells Weather-resistant IP68 protection against dust and water Includes carabiners for backpack or campsite setup Key features High-efficiency solar cells The panel uses N-Type TOPCon monocrystalline cells and is rated at up to 25% conversion efficiency. In practical terms, that helps it capture more energy from available sunlight compared with lower-efficiency panels of a similar size. USB-C and USB-A outputs The integrated junction box includes a USB-C port rated up to 20W and a USB-A port rated up to 18W. This allows two small devices to charge at the same time, depending on sunlight conditions and device requirements. Built-in angle guide A visual alignment guide is included to help users position the panel toward the sun. Correct placement can improve charging performance, especially during outdoor use where light conditions change throughout the day. Weather-ready construction With an IP68 rating, the panel is designed to resist dust and water exposure. The ETFE protective layer adds durability for outdoor use, including situations such as rain, sand, or damp environments.
