We’ve seen a number of Swiss Army Knife related products, but Wenger, the maker of the famous blade from the Alps has introduced something completely different, namely a solar panel for outdoor use that includes a built-in rechargeable battery pack for use with smartphone, tablet, MP3 player, digital camera or GPS device. The Wenger solar charger isn’t packed with blades, but it is multifunctional and can be used while stationary or even when hiking as it can strap over a bag or pack.
