Voltaic Systems is known for portable solar gear, from laptop solar chargers to solar panels that can attach to cars. Now they’re offering two solar backpacks on Kickstarter┬áthat provide plenty of power for whatever you are doing. Their Array backpack can even charge drones, which according to Voltaic Systems is “something no other backpack can do.”

The Array offers the most power with 10 watts of clean energy. It’s robust enough to charge laptops, tablets, smartphones, a DSLR camera, a GoPro, or a drone. The solar backpack comes with Voltaic’s 19,800mAh battery pack, which charges in 12 in sunlight and in four hours via a wall outlet. The OffGrid backpack, offering six watts, provides a boost for explorers who aren’t going quite as far but still need energy off the grid. The OffGrid comes with a 4,000mAh battery pack that charges in four and a half hours in sunlight and four hours via USB, with the option to upgrade to a 12,000mAh battery pack.

Both backpacks are designed to safely store electronic devices, and feature padded compartments for fragile items like laptops. The solar panels that adorn the backpacks are lightweight and waterproof. The backpacks are even made with eco-friendly materials such as recycled soda bottles.
