The Juice Bag from Reware is basically a Boat-n-Tote with a solar charger, and it's one of those mash-ups that makes perfect sense, like chocolate and peanut butter. Such multitasking is probably already familiar to the green-minded, who might already own a Voltaic backpack. But solar panels, like all technology, improve every year, and Reware's newest model weighs less and charges quicker than older versions. It's the new beach order: Keep yourself shaded and slathered in sunscreen but leave your bag out in the sun. Just remember to take out the ice cream bars first.
