I tried looking for a compatible MagSafe charger for my iPhone at Officeworks, JB Hi-Fi, and Kmart, but I could hardly find any. Eventually, I bought one on AliExpress that claims to have MFi certification. It needs to be connected to a PD port, and it charges my iPhone 16 at a reasonable speed. However, the phone heats up quite a bit after about 30 minutes of charging.
By the way, when I connect it, the MagSafe charging animation appears briefly. From what I understand, a MagSafe charger is basically just a Qi2 charger with magnets. My question is: is it safe to use a non‑MFi charger like this?
no it's not. I saw a test Qi (7.5W max on iP) vs Qi2 (15W) vs magsafe (15W).
only apples own magsafe charging thing (round thing with the cable) can communicate with the iphone. it smartly adjusts charging speed constantly to manage temperature better. Qi and Qi2 both made the phone a decent amount hotter than magsafe charger, but magsafe charges the phone just as fast as Qi2.
and it didn't make sense to me but yes the test shows Qi (7.5W) was the slowest and also made the phone hotter than magsafe did.
also keep in mind apple released the new magsafe charger with up to 25W. I don't think anyone has tested against others with temperature and charge times yet.
my advice don't risk your $1k iP with a charger from Aliexpress. buy the apple one.
also the official animation is easy to hak. they did the same with knock off Airpods.
