Water-proof USB power Ports.

As Bugnbrian said in another post, We are going to need USB power ports.
I have located a few that claim to be waterproof / weatherproof.

Here is a good write up on them from Web Bike World.

Researching more into a water-proof USB power port I ran across a Waterproof Dual Port USB Charger by Poly Planar Stereos for $25. It looked just like what I needed for my Pioneer. So I ordered it, 2 days later it arrives. To my surprise it is perfect for my needs.

A basic un-boxing has it looking like a fairly good product. It has 2 USB ports rated at first one at 2.1A and second one at 1.0A. The USB-PM can charge smartphones, tablets, GPS devices and Action Cameras. The USB charger also provides express charge mode for Apple devices, including iPad and iPhone.

Wiring is simple and is made by only connecting a positive and negative to the standard 12v system. The Dual-port USB design allows users to charge up two devices at the same time and with a flush mount design, installation is simple and clean.
I hooked it up to a spare 12v battery to test it out. I was surprised to see that the ports glowed a nice blue color so you can easily find them at night.

Pictures of install will come once I install the port.

Here is the USB dual port installed. Turned out great and fairly simple.
