Lensun uses ETFE integraded lamination technology on the solar charger NOT the cheap fabric, This ETFE laminated solar charger has non-adhesive surface properties. Highly stain-resistant and easily gets cleaned by the rain.
And ETFE integrated Lamination solar panels do not reflect the light. Dimple technology on the surface captures more sunlight and increases 5% solar absorption rate.
