When pulling it back off I saw what appeared to be slight black marks on the 2 and 4 pins inside the magsafe jack (on computer). Also noticed black marks on same pins on the aftermarket charger. Was concerned this was a sign of frying logic board or dc input jack. MagSafe is a proprietary magnetically-attached wireless power transfer and accessory-attachment standard used originally on the Mac series of notebooks. The new version was introduced by Apple Inc. On 13 October 2020, in conjunction with the iPhone 12 and 12 Pro series.

Since you can easily destroy hardware using this adapter, we really recommend it only for experts and people who fully understand what they’re getting into by pushing arbitrary voltages into their fancy computers! Use a multimeter to probe the magjack pins to verify you’ve got the right voltages before plugging in into your computer.
