As anybody who's tried to charge an electronic device using a solar charger knows, it doesn't juice up the device nearly as quickly as your typical power adapter would and the Surge is no exception. The charging case can provide up to 30 minutes of talk time on a 3G network or 60 minutes on 2G from 2 hours of direct sunlight. Novothink also includes a USB cable to charge Surge on cloudy or rainy days, though you'll obviously need to be near a power source--or a charged-up laptop--to recharge the unit.
In the company's marketing materials, it shows the Surge in an array of colors, but for now anyway, it's only released black and white models that you slip your iPhone or iPod Touch into. The iPhone version retails for $79.95 while the Touch version goes for $69.95.
