Never see red again
TuneJuice Universal is the ideal back up battery for iPhone, iPod or any USB charged device. When your device is on red, simply pop into a store and pick up three double AA batteries. I carry rechargeable batteries in my bag, so I’m always ready to rescue myself from the dreaded loss of power.
Of course, we include your first set of batteries, so you can break open the packaging and get charged right away.
This is especially perfect if you’re traveling, camping or anywhere that you need more juice.
