I’m surprised so many have the same issue as me with this product, I got this in April 2023 for my partner and the central piece (phone) stopped working overnight - I tried with different power bricks, cables, even phones to no avail.
Apple sent me to mophie/Zagg for support, I filled a replacement claim only to have it rejected - with the sole explanation the product is no longer available.
Went back to Apple for a refund as I cannot get a replacement, got tossed to 6 or 7 agents, only to be told they won’t do anything.
A $200 charger that lasts a bit over 3 months that gets no support whatsoever is the textbook definition of a scam.
Lesson learned, I just never expected this sort of crap from Apple (they don’t make the charger but they sell it).
