Looking for one. It seems most are cheap chinese things that don't really explain how they work. I want one that will hold Apple's MagSafe charger and mount via glue/screws to the dash somewhere... maybe a short goose-neck thing.
I don't know about the charger, but here's what I picked up for a mount. If you know just about every phone mount, GPS/Garmin/GoPro, etc.. that has that smaller ball mount on it, (that's about the size of a small marble) is this size. You can drill a hole through whatever, and this mounts with a 1/4-20 bolt.
