Interesting…. so this past week while out fishing I began using my usb charger for my cell and would charge my phone and Bluetooth JBL speaker, after my second trip I noticed the USB now no longer works, I plugged it into my truck and a message came up that the device was using an extraordinary amount of voltage to charge. Im wondering if the plastic USB charger is to blame. All the plugs worked and still work, but the usb adapter is fried. Thanks for the info. If you cant get up to aqua tech we can do some troubleshooting here at the house, let me know, Im over in plantation off Broward. I believe I still have a spare switch for the powerpoles, which is always a good place to start, assuming you have a rocker switch for the power supply to your poles.Last edited by JSLAW on October 11th, 2016, 11:18 pm, edited 1 time in total.
