Camp stove that charges phones!?

Yes. A camping stove that charges cell phones.
In NY after Sandy… Daily Beast

… And on the ground level, one of the most useful tools to emerge is a genius new spin on the most basic of emergency devices: the campfire.
The BioLite CampStove is about the size of a coffee urn. Developed as the hot new toy for hikers, the stove houses a small fire that burns from hunter-gatherer fuel sources—dry twigs, pinecones—and, in addition to warmth, generates electricity for users to charge mobile devices. You can cook on it, too. But with hundreds of thousands of people without power for days following the wrath of Sandy, and many in the New York region still in the dark, a serendipitous new function of the CampStove—disaster relief—has come to light.
“We realized some of these applications while we were developing it,” Erica Rosen, director of marketing at BioLite, tells The Daily Beast. “But it has really come front and center in the last week.”
The Wednesday after Sandy struck, a group of three BioLite engineers packed a car with four CampStoves and a folding table and drove to Lower Manhattan, where there was still no power, and set up a charging station outside Washington Square Park. They made a handwritten sign—“Come charge your phones for free and drink some tea while you’re waiting”—and quickly amassed a crowd of local residents toting dead phones who couldn’t believe their luck. Finally, a way to charge their cells and reopen crucial lines of communication with family and friends.
“One person was like, ‘Just let me know when this company goes public. I want to pour my life savings into it,’” Nissan Lerea, one of the BioLite product engineers who manned the charging station, says. “A lot of people wanted to buy the stoves from us right then and there, but we weren’t selling it. One person offered to buy it used on the spot.”

The manufacturer - Biolite CampStove. Note that its fuel is wood you find, not white gas or propane.
