Can I use this mag safe converter with a thunderbolt 27 inch display and my new mac air?
I have a 27 inch thunderbolt monitor and the power cable doesn't fit into my new mac air. I saw this mag safe converter and was wondering if I can use it to connect my mac air directly to my monitor.

Yes, you just attach the converter to the power cable from your Thunderbolt monitor. Then you will be able to connect your MacBook Air to your monitor.

Is this incompatible with MagSafe Airline Adapter?
The compatibility list does not list MagSafe Airline Adapter. Is it obsolete now?

The Airline Adapter will NOT (I repeat, NOT) work with the 15-inch Retina MacBook Pro. This may be why Apple discontinued the adapter, but Apple has not given a reason for discontinuing it.
To get technical, the Airline adapter transmitted an output of 16V. The 15-inch Retina MacBook Pro wants a 20V input.
You may ask why older MacBook AC adapters work, and why Apple offered a MagSafe to MagSafe 2 adapter. The reason is that the MagSafe AC adapters can modulate from 16V to 18.5V output. When a 15-inch Retina MacBook Pro is connected, the older AC adapters crank up to the max at 18.5V, which is close enough that in most cases... sufficient power is supplied.
I have not tested with the 13-inch Retina or the MacBook Air, but those appear to run at lower voltages (14.5V on the MacBook Air, for example). The Airline Adapter may work on those systems.

Will this allow me to use my old MagSafe model A1222 Adapter with the new Retina Mb Pro? Thanks!
Just want to be sure it's not too old to power the new model.

Yes it will, the A1222 is the 85W model which is the power needed to charge the 15" model MacBook Pro (Retina and Non-Retina). With this you'll be all set!

Is it better to get the adapter or just buy a new Magsafe 2 power supply?
I've got a brand new 2012 Macbook Air. Given my travels, I definitely need an extra power supply. I have some extra original Magsafe supplies (85W). I'm trying to decide if it will be better to get the adapter or get a new power supply.

My advice would be to buy one of these due to the extreme difference in cost. Use one of your old chargers plugged in to your desk at home (or wherever you normally charge at home) with this adapter.
Save your new adapter for "mobile" use... take it with you when you travel.
I have my old, original magsafe adapter that came with my Jan 2006 macbook pro plugged in at my desk at home. It's lasted so long simply because it stays in that one location and never moves. So leave your old charger at home with the magsafe adapter since the old one is more likely to fail if you continue to use/abuse it (simply because it's older).

No answers yet
Although I don't own one (yet) from looking in to this the answer seems to be:
- Yes, this will work if you have an old MagSafe power adapter for a MBP and want to use it to charge a computer using the newer MagSafe 2 port
- Using a higher rated power adapter is NOT a problem - will only supply the power that the computer connected needs, so no damage, no faster charging than normal
- Using a lower rated power adapter IS a problem as it will not supply enough power

You'll need a Lightning to 30-pin Adapter, Apple product number MD823ZM/A. It converts from the old 30-pin connector used by older iPhones/iPads/iPods and their accessories to the smaller Lightning connector used today.
Unfortunately, Apple's comment system won't let me post a link to their own online store. Check under Store/Shop iPhone/iPhone Accessories.

Which end is which?
There is a standard for describing electrical connections that is not used here. For 115 V AC, on the end of a cable one plugs into an outlet is a MALE connector. The outlet is a FEMALE connector. Is this gizmo a MALE MagSafe2 and FEMALE MagSafe1, or is it a MALE MagSafe1 and FEMALE MagSafe2. I think it is the former, but it's hard to be sure from the description.
MALE MagSafe2 and FEMALE MagSafe1 would allow charging of a newer computer with an older power adapter.
MALE MagSafe1 and FEMALE MagSafe2 would allow charging of an older computer with a newer power adaptor.
Each task is going to be desired by some users. Why is there only one kind of adapter?

This is a female MagSafe and male MagSafe 2 converter, allowing you to use an old MagSafe charger with a new MacBook.
I suppose the reasoning is that lots of people have older chargers, and they're buying new computers, so it makes sense to have an adapter like this one, but few people are going to be buying new chargers for old computers, since Apple still sells the old chargers. It's possible there are some people desiring an adapter that goes the other way, but it's likely a very small number of users.
