I have a phone charger on my bike. All i did was buy a cig lighter hard wire kit. (cigarette lighter with a positive and negative wire coming off it). I tied it into one of lights in the wiring harness so it only comes on when the bike is on.

I'm a cheap bastard, so I bought this $8 cable:

It plugs into this cable which came as part of my Battery Tender setup:

The harness is fused, which is reassuring. I routed the end of the harness to come out of the left side fairing hole. It tucks into the frame when not in use and is barely noticeable. When I want to use it, I just plug in the cig adapter and let that sit in my tank bag where I have a USB cig charger plugged in. It works really well.
