I had a DR650 and no issues charging my phone with a USB adapter. I even ran heated gear. I use a USB adapter hooked to my battery tender plug. I use it between multiple bikesThe DR650 does not have a ton of extra power generation, but it is plenty to charge a phone and GPS. There are a bunch of different ways to connect a USB outlet. Best to connect one directly to the battery. Here is where I have detailed some of my power solution.
