Smartphones have become our mailboxes, maps, cameras, clocks, calendars, books, and music players. In that spirit of multipurpose minimalism, we went on the hunt for some eco-friendly cell accessories.
Finally, a way to charge up while backcountry camping: With the CampStove from BIOLITE, you can warm your hands on the same fire that charges your phone. The 33-ounce thermoelectric gadget needs no gas. Just stuff in some twigs, set 'em on fire, and plug in. $130
The Guide 10 Plus Adventure Kit from GOAL ZERO, a company that claims to be the world's largest manufacturer of portable solar products, charges your phone (or tablet) anytime the sun shines. After dark, juice up with the kit's four rechargeable batteries — they come in a pack that doubles as an LED flashlight. $120
A phone case may seem like just another unnecessary thing to buy. But when you consider that a naked cell is much more likely to break than a protected one (remember, its outsides are made of glass), a cover starts to look like an ecological investment. The slim, stylish, and biodegradable Interchangeable iPhone 5 Case from INNOVEZ sports bright-colored style and two layers of buffering to prevent an early death knell for your cell. If you haven’t upgraded to the 5 yet, don’t worry: Innovez makes degradable cases for all versions of the iPhone. $25
