The official EcoFlow Suction Cup Set enables portable solar panels to be securely mounted on smooth surfaces such as glass, vehicles, or windows. This quick and easy installation solution requires no tools and is ideal for EcoFlow portable and flexible solar panels. The suction cups feature a strong, weather-resistant design and high-strength metal carabiners/hooks that attach directly to the corners of the solar panel. Ideal for van and RV travelers, as well as urban apartment dwellers, they let you mount panels on vehicle windshields, sunroofs, or balcony windows to capture sunlight wherever you are.
