The solar panels are waterproof, scratch resistant, and UV resistant. They use a high efficiency monocrystalline cell.
The three panels operate independently to generate up to 4 watts of power. This is double the power of typical solar chargers and enough to charge most portable consumer electronics (other than laptop computers). See typical charging times listed below.
The substrate is an aluminum / plastic composite, specifically designed to be strong and lightweight. They can easily stand up to typical outdoor use including being dropped and leaned on. |
