Does the speaker use a separate battery to chrge your phone?
If I'm using the speaker to charge my phone, does this diminish the speaker's run time? I was speaking to a JBL rep at the store (at least he was wearing a t-shirt that had JBL on it and he was hovering around the speakers) that stated the speaker has a separate battery and this would not reduce my play time even if I used all the juice to recharge my phone. I can not find anything to confirm what he said.
