Maybe i'm just looking in the wrong places, but I have yet to find a waterproof case that will allow for continuous charge. You know, like if you plan to mount a gopro on top of a boat tower & don't want to take it down all the time to change batteries. Further to that, wouldn't it be sweet to use the same usb charging cable to simply plug into a laptop down below to transfer and empty they contents of the sd card making it a truly integrated piece of hardware for the boat! I will modify a case to achieve this if I have to, just thought I'd ask around and see if anything is already out there. Thanks in advance for any help.
