The REVEAL Folding Solar Panel delivers serious power in a portable design. The most powerful solar panel we make, it charges up to 400% faster when compared to the V2 Solar Panel. The built-in Lithium battery provides up to 5000 photos a day when in direct sunlight. The foldable design makes packing into remote locations easy, and the new bracket design provides quick and easy installation. Use the Reveal Folding Solar Panel to directly power your REVEAL Camera or to charge the REVEAL Battery Belt or Lithium Cartridge for the ultimate combo for extended battery life. It's compatible with all Reveal cameras, Defend cameras, and most other 12V cellular cameras. We built the REVEAL Folding Solar Panel because we saw the need for two things-a solar panel with more surface area and power output, and a solar panel that was easy to pack up and haul into remote spots. This panel does both: it's an external power source for REVEAL trail cams with two 3.6W panels (over 2.5 times the power output of our other panel) that fold up so transport is easy, and it has a built-in 4900mAh lithium-ion battery for long-lasting power. Plus, we threw on a new bracket design that makes installation super easy. Now, placing your camera in remote or high-activity areas means you can go even longer without needing to replace or charge batteries.
