I agree with using the 12v power outlet, and the usb insert. That way you have the outlet to use to power other things if needed. Most importantly, buy a good quality phone holder. I purchased a cheaper phone holder from China. Out riding at 60 mph when the phone fell out of the holder and hit the highway. In the rear view mirror I saw my $500 phone bouncing on the asphalt and shatter into a million pieces. If we will spend $300 for crash bars to protect bike parts, in the event of a tip over, how much are we willing to spend to protect an expensive cell phone.
As far as how to wire the 12v outlet, I wired it straight to the battery using a fuse link on the hot wire.
