Hey, sorry, I know, we should let old thread die, but I thought my piece of information might be useful to somebody else.
I had a MagSafe 2 85W with a bad cable. I was in need of a MagSafe 85W to test a computer. I had a MagSafe cable (working) lying around.
I tried soldering it to the MagSafe 2 brick.
It doesn’t work.
It’s not the cable, the cable works. I put it on another MagSafe brick, it’s fine.
I put a MagSafe 2 cable on the MagSafe 2 brick, it works.
The MagSafe 2 85W brick will not accept a MagSafe 1 cable.
Or at least that’s my experience with it.
I also tested it with the older version of the MagSafe 1 cable, the T-shaped one (yes, the one before the L shaped MagSafe 1), same thing, doesn’t work.
that said, might be a limitation specific to the 85W power bricks.
But unfortunately that’s the one I needed and the 60W and 45W MagSafe 2 I have lying around are already repaired and I don’t really want to desolder everything just for the test.
but yeah, as someone was asking about that, I thought I might provide my answer based on my recent experience about it.
too bad about the absence of MagSafe 2 to MagSafe 1 converter. I’ll be selling my last MagSafe 2 device soon and I’ll have no way to test my chargers once I’ve repaired them. That sucks.
somebody in France tried grinding a MagSafe 1 to MagSafe 2 converter to revert it and pretends it works. I’m sure it does but I’m doubtful about it working on the 85W power supply. I might try it.
