As long as portable nuclear power sources are uninvented (or safe...) battery life is still the biggest struggle for gadget users. But with this solar panel included backpack you can give your laptop, iPod, cell phone or other gadget the juice it needs. All it needs is a bit of sun light. It has a special protective (removable) laptop sleeve inside, holders for CDs, pencils or keys and comes in three different colors. The power generated in the solar panel on the back is transferred through a standard 12V car input (cigarette lighter) for which every self-respecting gadget has an adapter. The side pocket even has a special outlet for headphones.
Lots of sun and a shortage of power sockets... sounds perfect for on the piste. That is if you don't fall on your back too often.
The solar powered backpack is cheapest on Amazon for $ 129,-
