MagSafe2 to MagSafe adapter (the other way around)

No, they do not make such an adapter.

 

Nope (not yet anyway...)

 

Apple will probably never make one either. Kickstarter in 3...2...

 

Since Apple will not license the MagSafe connector how do you figure that it will be a Kickstarter project?

 

Magsafe2 runs at a higher voltage than Magsafe, so I don't think Apple will make one.

 

It does? Interesting... What voltage does each run at?

 

They'll continue to sell chargers for older models for quite some time, if something ever happens to yours.

And if they change the Thunderbolt Monitor to Magsafe 2 in the next refresh, they'd probably create an adaptor so it could be used with older Macs.

 

Magsafe 2 runs at 20v; magsafe runs at 16.5v (and the macbook air magsafe actually ran at 14.5v).

 

Very interesting. I wonder why they did that? Maybe to lower the current (amps) under full load because the smaller connector pins can't carry as much current? Probably also means that the older 85 watt adapter with "MagSafe to MagSafe 2 converter" won't supply all 85 watts and will take longer to charge.

Thaks for the info!

 

That bites. My old cable is shot to pieces and i was hoping to buy a second MagSafe 2 adapter to use with both systems. If there is any news on this please update. Am I right in saying that an adapter converting down to the MageSafe 1 is not possible in terms of voltage?

 

Right. Well, the system may be able to handle 20v without failing, but Apple won't make an adapter (and will cite the voltage difference as the reason if pressed on the issue).

Why not get an 85w MagSafe 1 and an adaptor and use that with both systems?

 

This is what I do, especially since I prefer the L shape.

 

Yes, or you can buy an extra Magsafe 1 and an extra adapter and sell your new one.

 

I already purchased an extra Magsafe 2

 

I have a 65w A1435 Magsafe 2: 16,5v and 3,65A

Same voltage

 

I made that post before the 65w existed. The 85w is 20v @ 4.25A

 

The did t hat so that they can screw you out of another $100 for a different adapter. There is no reason to do this other than to drive sales.

 

Would it kill the macbook if one simply filed down the edges on the MagSafe 2?
