I regularly find myself needing to charge my phone and not having an outlet available. Having a spare battery in a single waterproof package is just more convenient for me. It lives in my backpack, and I don't need to care when the rainy season hits. Plus, since I use my phone as both a camera and a GPS, I can take the Novobeam with me while backpacking to keep my phone topped up.
