A:AnswerShould not be a problem at all. I would not put it in a bucket of water and freeze it.. that may be a problem, but storing in a shed or garage will not effect it at all. After all, you did buy a Sony product...
A:Answerfor that you might as well leave it plugged in all the time because trying to stay on top of the charge would become a job. also you might want to look into the Logitech Bluetooth transmitter ($60) because you would have to get an mp3 pigtail adapter for both speakers. Plugging in One speaker will not sync to the other
A:Answertry using the phone app first to sync up. If your pc does not have bluetooth then you wont be able to sync up. this is a bluetooth speaker not a wifi speaker
A:AnswerIt says that it is waterproof...obviously, submerging it wouldn't be a good idea...but I used it by a swimming pool and hot tub..with several people splashing around..and I never had a problem. I think it would be fine for your boat.
A:AnswerIt uses a standard micro usb...just like any android phone. So as long as you can charge a cell phone (other then iPhone) you can charge it anywhere.
A:AnswerHi Listens2Sony, it may but it is not going to be a perfect fit as it measures approx. 7.80" x 2.68" x 2.72" (W X H X D). Additionally, it is not suggested as it may move around or rattle inside the bottle holder if it is going to fit. Regards, -Mark
