Now... I got a question. What happens when you cut off the magsafe cable from a 45 W adapter. Lets call that cable A.
Now then cut off another magsafe cable from a 85 W adapter and call that cable B.
What happens when you now swap the two cables and have cable B soldered onto the 45 W adapater and cable A soldered onto the 85 W adapter.
Would it work like normal? Or would the ID confuse the Macbook into thinking that it's connected to a different watt-rated adapter and draw more power and cause problems?
PS: I have a Gogal Zero Sherpa 50 external batter and I am thinking of soldering a Magsafe connector to the 19V output port on the Sherpa. Anyonebody have information about this plesae please email me at markwienands(at) gmail (dot)com
