It's easy to upgrade Winnebago's factory-installed USB ports to provide faster charging (NB: for non-Apple devices!), and depending on which replacement model you select, you can get a nightlight with it, too. I chose this model for about $16, and it took about 15 minutes to install. Here are the steps I took to replace the USB ports under the galley cabinet:
Remove the two screws in the USB port's faceplate.
Remove 4 screws inside the bottom of the dinette cabinet, along the front edge.
Use a flathead screwdriver to gently pry the bottom of the cabinet up. Notice that there are staples in certain areas, so you need to gently work them out as you lift the cabinet bottom 3 inches or so.
Put the new USB port in the original faceplate, attach the new USB port to the existing wiring (Yellow is +, White is -), and put the port back in the hole in the bottom of the cabinet. Use the new USB port's lock ring (red arrow in the above picture) to tighten it against the cabinet.
You now have new, higher powered USB ports that indicate current voltage, and the LED provides a small night light. If you don't want the night light, then you can cover it with a small amount of nail polish. Thanks to Jim Lincoln in the Revel Facebook group for the part number and inspiration!
Pull the USB port down (gently), and notice that WHITE is NEGATIVE polarity in Winnebago's wiring here. Disconnect the wiring simply by pulling.
