Review on Nillkin Magnetic Air Vent Phone Holder with 10W Qi Fast Car Charging - Compatible with iPhone 11/11 Pro Max/Xs Max/XR/X/8 Plus, Samsung Galaxy S10/SE10/Note10/S9/S9+/S8/S8+ and More by Rey High

We have 4 of these. We've been using two a day for over a year. They worked great on our iPhone XR. My wife has one in her car and I have one in my car. It is very convenient for both of us to have the same magnetic charger. It hangs securely on the air outlet. No problem with that. The magnetic force was strong enough to hold the iPhone XR my wife and I have. The only time it fell off was when I accidentally hit it pretty hard with my hand when I was reaching for something in the glove box etc. It might have fallen off once or twice hitting a pothole from hell have. Otherwise it was tough. I love that I can position my phone vertically or horizontally and it stays in that position. When I get out of the car, all I have to do is pick up my cell phone. There are no levers etc to deal with. That's the magic of magnets. I have a phone case and so does my wife. The phone will charge normally. When I bought it for my daughter it didn't always work. However, part of this may be due to the Mazda 3 not delivering enough voltage/amps to the USB port. I've found it works well when using one of my USB adapters that plugs into a 12 volt cigarette lighter plug. There must be borderline USB power and use of a phone case, possibly combined to cause an intermittent connection.
