A:AnswerMy old magnetic mount wasn’t strong enough to hold the phone by itself or with this case.
So I purchased the Zeera MagSafe car mount/charger and a higher wattage cigarette charger plug in. I get a very secure hold with the Apple Silicone MagSafe case and faster charge at the same time.
A:AnswerI tried this today with my Moms phone and yes it holds well. I currently have the clear case but it is slippery and I do drop my phone easily. So I tried hers which has the Red silicone case and it works the same as the clear on the MagSafe car clip by Belkin.
