This MagSafe-compatible iPhone 12 car mount keeps your phone securely in place while you drive. It attaches to a vent to hold the phone in place magnetically; However, the phone doesn't charge via wireless charging like some models. This circular mount is barely larger than the circle on the back of the phone, making it perfect for stowing in your travel bag if you're renting a car and want to use your iPhone for navigation. It has a pivot point to place the phone where you or your passenger can see it. Surprisingly, the phone doesn't move unless you move it manually. Because this mount requires an open MagSafe ring, it can only be used when your phone is not in a case OR if you have a special MagSafe case with a ring on the back to increase the phone's magnet range. It doesn't securely hold your phone in a case other than MagSafe. – Debbie Lee Wesselman.
