Iphone 14 Pro max won't charge via magsafe unless I unplug the charger and plug it back in.

Hey, all. I have received the iPhone 14 Pro Max for Christmas, as well as a magsafe charger and an a/c to USB c adapter brick.

Essentially, the phone won't charge via the magsafe charger unless I unplug the charger and plug it back in. Other than that, it charges fine and it charges to full every time. It only happens if I take the phone off for more than a minute. If I take it off and put it right back on, it continues to work fine.

I'm on iOS 16.2 if that helps. I've seen on the internet a suggestion to restart the phone a d hard reset, and neither of those worked for me.

I am unsure of the brand of the A/C to USB C adapter, because it wasn't on the box. Could the adapter be the problem?

Should I try purchasing the apple adapter? Or is that not the problem? The magsafe charger is from Apple. I have two of whatever brand the adapter is.
