I’d message Apple about it. Might have gotten fried during a power surge. I had an issue with a 20v charger that stopped working all of a sudden. Messaged Apple and they sent me a new one and I sent the old one back.

In short, not exactly worth the extra money to invest in a 20W brick + a MagSafe *if* you’re looking for speed or already have your older wireless charging setup. It’s barely faster than charging through a 5w.

If you already have a 7.5w wireless charging setup, and do not wish to invest much more on accessories, don’t bother with the 20w brick + MagSafe, it’s not really gonna be faster (only barely). Unless, of course, you really want the benefit of the magnetic circular alignment.

The non-Max models barely reaches half the 15w speed as apple promises. And right now there isn’t a max model to be openly tested yet so we don’t know if it’s the same case. On the currently available models it more consistently pulls around just 6w instead—way under the promised 15w (yes the promised 15w is the peak, and the 7.5w Qi charging doesn’t stay at 7.5w either, but the reality is obvious, the supposedly 15w setup isn’t really faster than your older 7.5w ones. So do not upgrade to this setup *if your only reason is for faster charging than your current ones*, cuz it won’t)

Also, anker’s 20w somehow yields noticeably greater speeds than apple’s 20w (charged via lightning connector)
