New MagSafe Airline Power Adapter a boon for MacBook, MacBook pro travelers

In our MacBook Pro special report, we noted that the MacBook Pro does not work with power sources offered on some airplanes and in automobiles. The issue is excessive power draw, as units can be charged from the inverters while powered off, but exhibit issues when turned on (while charging). The MacBook Pro draws 85W of power, while most airline power inverters supply 75W or less.

Apple has now largely obviated this problem with the introduction of the MagSafe Airline Power Adapter, which works with in-seat DC power ports available on many commercial airliners ? both EmPower ports and 20mm ports.

Unfortunately, while the MagSafe Airline Power Adapter provides power the computer, it does not charge the battery. Also, the MagSafe Airline Power Adapter is not compatible with automobile power ports.
