Recharging your USB devices on the go becomes easy and hassle free. All you need is a bright sun on the sky and your Bushnell SolarWrap 400 Solar Power Charger. It gathers power from sunlight and can also work on an internal lithium ion battery providing high power storage if the sun doesn’t come around. The solar panel can be unrolled like a scroll and can fold up into a transportable case you can easily fit in your travel bag or backpack. There’s also a micro USB port so that you can pre-charge it at home. The setup has enough power to charge cameras and GPS units 2.5 times, MP3 players twice or even a smartphone.
