AC power adapter for MacBook, MacBook Pro, and MacBook Air. Uses a self-aligning magnetic connector that disconnects safely when tugged. First-generation (2006-2012) MagSafe chargers have a slightly thicker, L-shaped connector. Available in 45 W, 60 W, and 85 W versions.

85 W adapter only registers as 60 W adapter, help?

I did this cable repair recently on an apple 85W adapter (not counterfeit, the one that came with the laptop purchased directly from apple) and the system now reports that the connected charger is 60W instead of 85W. Any idea why this would happen?

Is this a good question?

Download and run Coconut Battery and see what it tells you about the Mag-Safe.

You should buy a 85W cable, it will work.

It looks like the 60W cable but different component inside the plug.
There is three types of cables: 45W, 60W and 85W.
A 45W cable soldered to a 85W charger will charge with only 45W.
