Would you put a gas-powered iPhone charger in your pocket?
Batteries are expensive, so it makes sense that device makers are in no hurry to cram in more capacity than is actually necessary. The downside of this, of course, is that if you're out and about, the responsibility of keeping your hardware fully charged is yours alone. Most people overcome this, either by attaching themselves to any available wall socket or keeping a rechargeable power pack in their bag. eZelleron, however, is hoping that people will want to carry a small gas-powered generator in their pockets instead.
