Battery life is one of the biggest limitations for mobile devices. PDAs last for days at a time as they are not used as much or extensively as other devices. But notebook computers, cell phones, smart phones and other things consume a lot of juice – especially when in use and not on “stand by”.

The companies say their traveling generators provide enough power in one compact mobile unit to keep your cell phones, iPods, PDAs and most other personal electronics ready to run.
