$36 to $50 elsewhere I looked.
This one does not charge your phone.
It doesn't say but I think it's recommended for Magsafe on iPhone, many reviews say if using the included metal ring stickers on your phone/case the magnetism is very weak.
I considered getting this but decided not to after reading a comment on the recent Cygnett Maghold (with Charger) deal. https://www.ozbargain.com.au/node/813962
comment said the friction vent grip manages to slowly lose it's grip and come off when hitting a bump. my old spring "clamp" phone vent holder with the same friction grip has never come off, but I think it's because the Cygnett is so large and protrudes so far out it is too heavy for the friction grip.
Still if anyone wants to give it a try for the convenience of Magnetic attachment.
I’m speaking for your car because it can’t speak for itself :P - don’t buy this if you value having your vents remain in one piece. Phones are heavy these days.
