What phones? And what model Outlander is it?
Not sure if this is any help or not. I was having an issue with mine not charging too, but it wasn't that it was not charging all the time. The problem was that my phone was sliding around in the charging tray and moving off the point where it needed to be to charge. I designed and 3D printed a frame that sits in the tray and holds my phone in place and now I don't have an issue anymore. This may not be the case for everyone on here, but it certainly was an issue for me with regards charging.
