So more than 6 months after having my Pandora, I just used it on a cross country flight and killed a battery on the WAY BACK. It made it from Oakland to Philly with a stop in Vegas and still had a nice chunk of battery left. My gripe is this battery box, I'm trying to charge the battery I let run dry on the way back and I can't open the fricking thing still. Its a task. If you know of an easy way, please post a video or step by step. If you think I'm crazy, I hope you ordered an extra battery to understand.
