iPhone 12 won't charge on MagSafe chargers

I can't get the MagSafe chargers to work with my iPhone 12 Pro. It charges fine with Qi wireless and standard chargers. I've reset the phone countless times and I've tried charging on two different MagSafe chargers - Both with the same result. Every once in awhile the MagSafe will charge the phone but most of the time it just slowly drains. My iOS software is up to date... Any ideas??
