The EcoFlow 220W Bifacial Portable Solar Panel delivers next-level efficiency with a smart two-in-one design. Featuring a 220W primary side and a 155W rear side that captures ambient light, it can generate up to 25% more solar energy—and up to 80% more when used on reflective surfaces—charging your portable power station faster than ever. Built with a thin, one-piece tempered glass construction, it’s five times tougher than comparable panels and engineered to withstand extreme heat and harsh outdoor conditions. Despite its power, the panel remains compact and portable, measuring 10% smaller than similar 220W panels. A versatile carry case doubles as an adjustable kickstand for optimal sun exposure, while the IP68 waterproof and dustproof rating ensures reliable performance in any weather.
