I have Spigen case for 15 Pro as below. I also bought that Anker MagSafe nano power bank. I have to say, the magnets they put in this tiny thing are one of the strongest I deal with in MagSafe accessory. If I want to remove the power bank from the phone, it is easier to do it by sliding it to the side than by pulling it towards myself. But it won't go away easily, that's for sure.The review says that the magnets in MagGo Nano Power Bank are strong. But does anyone know if they are strong enough to hold the powerbank to the phone with a case (TPU, thickness 1 - 1.5 mm)?
