Using it with the Apple Leather case on a 12 Pro Max, I noticed that this didn’t align reliably and would be crooked. Also noticed that as it attaches you can hear a spring type of vibration. So disappointed as this was a nice backup battery to leave in my backpack.

While Apple products are highly advertised as “thee best”, I must disagree on this particular product. For the record, I have ALL Apple products: iPhone 12pro, 3 iPads, laptops, iMac, etc. 1. I should’ve waited until the next generation of this battery pack because it doesn’t charge my phone as much as it should for $99! They have not gotten all the “kinks” out. I have other “off brand” battery magnetic packs that charge far better and longer. If you’re paying $100 for a battery pack, shouldn’t it actually CHARGE your device fully (and not 50-60% as other reviewers have also noted)? Apple missed the mark on this and I will be returning it. 2. There is no light indicator to show if it’s charged or dead. So it’s a huge gamble as to whether or not your devices will be charged. 3. Don’t buy this 1st generation @$99. Wait until they improve it.

It does what it supposed to do but I would rank this product in the same category as the apple mouse. Neither are great products but they do what the designers intended. The battery slides around, doesn't really provide any feedback on the charge status (unless connected to the phone) and isn't sufficiently powerful enough to run the phone without draining the phone battery.
