Ditch the batteries and power up your sound and light with products from Solarrific like the 4-in-1 flashlight that’s also a radio, cell phone charger, and panic alarm (wind it up for one minute for a half hour of power), the AM/FM/WB radio (operable on solar or hand-crank power), or the Solar Cooling Hat. The code "MNN" at the Solarrific Website gets you the discounted price of $25 for the flashlight and radio and $20 for the hat.
