I don't have a MagSafe charger, but Apple made the MagSafe and Qi wireless charging a PITA if you use a thick, protective case on you iPhone 13 Pro Max. I always use an Otterbox Defender case on my phones, and after paying $1200 + tax for my iPhone 13 Pro Max I definitely want to protect. Unfortunately, Apple designed the newer phones where they cannot reliably be charged via MagSafe or Qi. I just use a wired 20W charger plugged into the pathetically outdated, proprietary lightning port. I tried a few different Qi chargers, but none were reliable. I never had a problem with my iPhone XR in an Otterbox Defender case though. Darn form over function Apple design philosophy sucks.
