Not trying to worry you but I thought I’d start MagSafe charging with my new 14ProMax. I brought an ESR brand 10000mAh powerbank/pass through one with a kickstand. My battery health dropped in 1 month. I also had “charging paused due to heat” messages sometimes. It could be coincidence but I stopped using it and went back to 20W Apple charging via lightning cable and my battery health stopped dropping and has remained the same. I do have a separate MagSafe mounted to the air vent in the car though and I do use that still. Make of all that what you will🤷‍♂️
