When we first started this project, we did have the preliminary OK from them, but since then, Apple has changed the MFi standards for this type of product. We have since learned that they now require one of two things for MFi:
1) It is required to include a permanently connected cable.
2) A power bank built in.
1) Your iPhone runs out of power on the go right? So you have a power bank for that reason. We said no to more batteries and yes to simplicity.
2) It would be more than 2-3 times the size. “Is that a power bank in your pocket or are you just happy to see me?”.
3) Oh did we mention that it would cost twice as much to make? That means a lot more money for you in the end.
