Goal Zero

Boulder 50 Solar Panel

All your climbing friends ask to charge their phones from your Goal Zero battery the moment everyone gets back from camp. You'd rather they didn't take a billion climbing photos every time they go to the crag, but the Boulder 50 Solar Panel powers your battery while you're away, so there's no real harm. State-of-the-art monocrystalline technology in Boulder panels deliver more power per square inch than any other solar technology available, and Goal Zero wrapped it up in a rugged, durable, rigid, waterproof, and impact-resistant housing for protection from the elements.
