Griffin Technology said today that is now shipping TuneJuice, its $19.99 battery backup device for the iPod and iPod mini. TuneJuice uses a single 9-volt battery to provide up to 8 hours of additional power for any iPod with a Dock Connector port. (It will provide 4 hours if your iPod is completely drained).
“TuneJuice is perfect for extending the play time of your iPod for those times when you just gotta have more than your iPod battery can give,” says Griffin. “It’s the perfect carry-on for airplanes, road trips, camping and ski trips. Anytime you need some serious play time and don’t have access to charge your ‘Pod, TuneJuice is a lifesaver.”
