JOYROOM 15W Qi Fast Wireless Car Charger with Auto-Clamping Phone Holder - Compatible with iPhone 16 Pro Max/15 Pro, Samsung S24/S23 - Perfect for Dashboard, Windshield & Air Vent Mounting - Keep Your Phone Charged on Road Trips & Daily Commutes

I've used a lot of in-car phone holders over the years, and this is the first I've gotten with a motorized grip -- that is, where it closes on the phone automatically and then releases with a button press when you're leaving. This works great. It automatically opens when you start the car and the USB port powers up, and then when you power down, you press a button to release and the motorized arm opens. Much better than the spring-loaded ones.As for installation, that was as easy as it can get. It uses a combination of a sticky-gummy part which is inside a suction-based contraption, and between those, it holds firm. Don't plan on repositioning (thanks to the adhesive part), so get that right the first time, and once you do, it's going nowhere. It holds. Alternatively, you can use the nice solid vent mount. This one is among the best vent mounting I've used. I used that for a couple of days while giving lots of time for the adhesive to cure before putting weight on it. If you stuck with that, it works very well too.The arm gives a great deal of flexibility for positioning and is reasonably stable. There is a bit of jitter as your car is moving/bumping along, but not excessive, and I'm not sure that is entirely avoidable with these materials. So far in a couple of months I haven't had the pivot points losing their positioning. The one swivel point directly behind the actual holder (where it attaches to the arm) does eventually start to become slightly loose so that the phone starts drifting into more of a tilt, but hand-tightening it gets you another few weeks. Plan on tightening that part every few weeks because it looks like it's the point where it will be working itself loose over time with regularity. Maybe that's an opportunity for the manufacturer to develop an improved locking mechanism.I've had nothing break so far, but I do get the feeling that the motorized grip mechanism and button don't FEEL especially solid, so it won't surprise me if something breaks earlier than I'd like. We'll see. That's currently just my perception so there is no actual evidence that this will happen. Will report back if it does break. ((Update after 10 months: It is still holding up just fine))Updated review regarding the charging ability: Previously, my review indicated that it just barely maintains the phone's charge level (Pixel 7 Pro here) but wouldn't add to it. Well, turns out that there was some kind of change to either charging or power utilization in one of the firmware updates that has completely changed how the phone charges wirelessly so that now it can actually charge very well on this charger and with less heat than it was generating while charging before. So now if I head out with 85% battery, it has a good chance of being near 100% by the time I'm at my destination. That's good.So updated conclusion as well -- the sort of delicate feel (a lot of cheap plastic) hasn't so far led to any breakages. The adhesive on the dashboard has started coming loose a bit as the weight of the phone on the arm is pulling on it, so I expect that I'll have to find something like what was provided to reattach it at some point soon, but I can't deduct for that because if they made it any stronger it would probably make it too difficult or impossible to remove later on. The suction cup did come loose just once in nearly a year from that circular metal plate that's attached to the dash via adhesive, but again that's expected with suction cups as well, and once I reattached, it hasn't come loose again. Charging has been great since the firmware update. The motorized open/close works perfectly still. So I'm upping my score from 4 to 5 and fully recommending this charger/holder.
