ProClip, no contest. They have an option for a charger as well. And it mounts in an outstanding location, at least on my MINI.
Although on the bike, because ProClip won't mount to a 2 inch aluminium handlebar or stem, I have a Slip Grip Car Mount on that, very solid, and a little smaller than the ProClip which is nice on the bike, and Slip Grip also has options for a couple cases.
Personally I was surprised how fast these came out in comparison to how long I had to wait for them to release for the Evo LTE.
