Ralph Lauren's solar-panel backpack charges your phone in hours, your credit card in seconds

Ralph Lauren outing its first solar-equipped knapsack as part of its RLX sports line. Four solar cells around back harness the sun's power to generate 3.45 watts -- completely juicing up an iPhone in a purported two-to-three hours, assuming you've got "proper sunlight orientation," of course. Like the optional orange hue (it also comes in black), the sun-sucking cells aren't particularly low profile -- but for $800 don't you want something special?
