Splice Magsafe 2 cable + Magsafe powerbrick?

[ndlundberg]

Hey Guys!
I've got one 60w magsafe power supply on which the cable has broken on the computer end and a magsafe 2 45w power supply on which the cable has broken closer to the brick end.

I'm wondering if it would be safe to cut away the broken part of my magsafe brick and splice it with my fully functional magsafe 2 cable?

i wouldn't. Of course i'm not an electrician, but i'm assuming you aren't either which is why you are asking here

if it were me i would just buy a new one. i have done some basic electric work (running romex, installing fixtures etc) and whatever hack-job i would do repairing a computer adapter would make me too nervous to plug it into my $1000+ machine, you know?

Have to agree here. Would not want to take a chance, especially if I was not qualified to do it. Would hate to damage my laptop because I did something wrong putting the wires together. Would be an expensive lesson to learn.

Well, I suppose you guys are right – it would be stupid to plug it in fingers crossed. And no, I'm by no means an electrician.

I can't imagine how it could go wrong tho. But wouldn't try it unless someone confirms it.

What you are suggesting is that Apple's Magsafe to Magsafe 2 adapter is a fire hazard. You guys need to think this through. There is absolutely zero reason this won't work except for the fact that the guy asking doesn't know enough to do it without asking.

No, what I am suggesting is that the joke (not subtle at all) was missed.

Did the smilies not give just a tiny hint?

OP. Go for it...no harm in it. Just make sure you match up wire colors. Task is simple. On a more difficult side, the wire may be solder resistant-ish....meaning you may need a hot iron to complete the task.

I've done this lots of times. Like the post above says, triple check the colors so you don't reverse positive and negative.

That said, I always double check with a voltmeter after soldering.

I fall solidly on the side of the previous posters - if you have to ask, don't do it. Likelihood of a problem if you are careful? Low. Damage if you do have a problem? High...

I've got some electrical training and have done this sort of thing before on all sorts of chargers.

My opinion? It's a stop-gap until you wait for the replacement to arrive. It's a pain in the ass, it breaks, it shorts out, and there are all sorts of problems. Just spend the money and buy a new brick, avoid all the hassle.
