How safe is it to replace the magsafe 2 connector with another one by simply connecting the wires?
This is the low voltage side of the transformer, so the risk is far less than working on the AC side. I haven’t heard of anything worse than scorch marks and safely melted plastic on the low voltage side when people shut these cables in a door or roll chairs over them, so I’d say you’re pretty safe if you make sure it works and doesn’t heat up and protect it electrically. The low voltage side has enough power and current to start a fire, that is certain so I’d say you are risking safety if you don’t do it well or there is hidden damage you don’t catch and fix.


Why doesn&#39;t a stripped/cracked MagSafe power cable shock?
Will the &quot;cracked&quot; wire of a MacBook charger eletrocute me
Out of warranty MBP ,Burned Magsafe port and frayed charger cable - repair option and cost?


So, if you know this and try a repair, worst case is you pay for new part or someone skilled at electrical work to do a repair if you’re not comfortable with your safety and whatever house you leave this plugged into going forward once you have learned if you can do the repair. The chances of breaking your Mac is low with this since it’s designed to not charge from damaged cords anyhow.

Since you probably should try this for science:


Are the silver wires inside the MagSafe cable necessary?
What are specs of this MagSafe wire, and what is its purpose?
What voltage readings should i get from my 60 watt magsafe
