Rugged and adventurous.

Designed to go anywhere you go. Whether you want to charge a GPS device in the middle of the forest, or charge your phone on a road trip, these solar panels will step up to the challenge. Made from a flexible optic polymer and fortified with an outdoor rated canvas, these rugged solar panels can survive a cramped backpack, water or the harsh sun.


Get up and get out there without having to worry about a dead phone or other USB device. As long as the sun is up and shining, keep your devices charged directly from solar power. When the sun goes down, use the portable battery pack for hours of additional use. Whatever the weather, we have you covered.

Extremely efficient.

Twice the power, folds to half the size.

Designed with the top-of-the-line monocrystalline solar technology, it converts over 18% of the sun's total power. In fact, our solar technology generates three times as much power as thin-film amorphous technology, but in a compact and efficient form factor.

Outlet anywhere.

Don't be glued to the wall. Keep your personal devices fully charged wherever you are - by the pool or on the beach. Portable power means you live life on your terms.

Stay connected.

Compatible with your favorite devices, like iPhones, iPads, GoPro's and more. It provides fully regulated solar power to keep your devices charged and ready to go - with zero risk of overcharging.


Fits in your backpack or satchel much better than a 100+ foot extension cord. It weighs less than a pound, which is less than two packs of AA batteries. So you won't need to compromise on what you bring on your next adventure.
