Shine: A Portable Wind Energy Charging Unit, An Idea Straight Out of Hell

There are many devices that help campers charge their electronic devices. One we covered earlier uses hydrokinetics; it’s a small water turbine that costs about $100 that is placed into a nearby fast-running stream or river (as if most campsites on Earth happen to have one).
Here’s one (pictured) that uses wind energy, that’s actually even more idiotic. “Shine” (perhaps a better name for a solar product?) costs $240; it adds weight and takes up space in a backpack, and works, obviously, only when the wind is blowing, unless the customer/fool carries the battery along too (more weight and space).
Speaking of solar, the only intelligent way to charge way-off-grid devices is a small, lightweight strip of PV, available everywhere for about $20.
Btw, what seems easier: setting up the mini-wind farm shown below, or throwing a tiny piece of PV on the ground?
