The unnamed blogger at "Yosemite Outside" would probably be interested in this. Months after going through pains to assemble a DIY backpack solar charger, this rugged and creative individualist can now buy a remarkably similar item that doesn't even require any unsightly duct tape.
The adjustable "Mana Solar Claw" can apply the sun's energy to a backpack of practically any reasonable size, keeping one's phone and gadgets charged at all times with an array of six-watt solar panels, according to ProductDose. It does cost $230, but that's a lot less than you'd pay for a $670 solar computer bag, not to mention bigger too. There's even an individual laptop compartment, which can be battened down with flexible nylon webbing and buckles. And as one astute reader points out, something like this could come in quite handy while camping.
