    Regarding the 75W/seat limitation, on a 757 the seating configuration is ABC DEF, with two Powerports (on American Airlines) shared by three seats. Perhaps there's an adapter that would bridge two Powerports...

    There you go. Now your thinking

    You probably know that, if you fly AA like I do often, power ports are only in the first 10 rows + emergency exit rows, aside from 1st/Biz Class seats. Sounds silly to have wires tangling up passengers trying get out in an emergency but these coach seats are mostly occupied by frequent flyers with the seat preferential service.

    The power allocation is for the whole aircraft so it depends on just how many ports they think it will be used at any given time. You can imagine on 747-400, 1/3 of the aircraft is dedicted to premium class seating (closer to 45% if you fly BA or Singapore), but it also has 4 engines i/o 2...of couse with much less passenger density.

    Where is the crafty electrician who can splice a mag-safe plug onto an IGO? CON-vert instead of IN-vert.

    I was thinking the same thing - I have done this before when I had odd connectors that I could not buy.

    1) Buy second Apple power adapter
    2) Cut off the magSafe connector
    3) Buy an airplane adapter that can output the same voltage as the Apple adapter - it's written on the Apple MBP adapter
    4) Cut off the airplane adapter's plug and splice the MagSafe cable to it.
    5) Done.

    I read in the repair manuals that the MagSafe connector has 5 pins - a connector pin, 2 positive and 2 return pins. So the cable should just have 2 wires. The main problem seems to be finding an airplane adapter that doesn't have some sort of "smart" voltage adapter system.

    Or you wait two months until some company - perhaps Apple - offers a commercial solution

    I have to agree with you. I travel on planes at least 2x week, and the only reason I have yet to 'upgrade' my AL PB is that there isn't a good solution for the air travel.

    I have used, successfully, the older madisononline air adapter eventhough it is rated as underpowered, because of it's size. When traveling as much as I do, every ounce starts to add up. The thought of carrying multiple batteries isn't even an option.

    I'm a photographer and work internationally. I depend on my Apple laptop for getting work done. Three batteries keep me going for most domestic flights and east coast to Europe. Traveling to/from the Pacific region from east coast US and I'm up a creek for getting work done with the MacBook Pro.

    According to Lind Electronics (lindelectronics.com), they do not have an airliner power cord for the MacBook Pro. They DO make excellent airliner seat power cords for Mac PowerBooks, however, tell me Apple will not license the MagSafe technology to third parties.

    I'm a patient sort and didn't complain much waiting for availability of spare batteries, but I see no sign of Apple or anyone working on a solution to this.

    Will someone from Apple spreak to this?

    Don't forget, you can install the CHUD processor tools (look for it on versiontracker.com) and turn off one of the cores in your dual core macbook pro. that should drop processor use substanstantially, and still give you a single 2 ghz or so core to do work precessing or dvd playback.

    Easy! You can swap batteries while the computer is asleep (try it!).

    I wanted to make a comment regarding the Mag-safe connector. Someone critized it as
    "apple-cute."

    I call it a GREAT Apple improvement!

    Especially, since my previous 2 Powerbooks had to be sent in to Applecare for repair due to the previous power connections breaking, either in the Power Brick or the Power Board in the PowerBook!

    I have the same problem as I also do a lot of traveling and have some international trips coming up this month.

    Has there been any update to this issue?

    Larry,

    I know you fly a lot on United (saw you in First on UA 870 from Sydney to SFO on March 5 for example). As you know, United uses the Empower solution for power, and prior to the MBP, you could RUN (but not charge) your PowerBook with a simple cable from several suppliers including Madsonline.com. No adapter required, just the right plug at each end. Madson tells me that Apple has not (yet) released the specs for the Magsafe connector so no third party can make adapters or cables yet. Hopefully they will soon, or perhaps Apple will make their own EmPower cable. The MPB should run fine with such a solution. The discussion about wattage largerly refers to CHARGING the battery, not running the machine.

    Ole

    I am a frequent traveller as well. I usually jump between the airline lounge and the airplane and vice versa. All the while plugging in when I can. Usually I find that I keep at least 60% of my battery power.

    I only just got my MBP and have not been on an airplane with it so this thread is great.

    My temporary solution, if I was not fully charged when plugged into the airplane power, would be to put the computer on sleep or shut down and let the battery charge up. Once it is fully charged - hopefully in less than 30 minutes, I can get working again.

    PS.. On a recent flight from London to Singapore on Singapore Airlines (before MBP), I was plugged in and fully charged the whole time. And I was online wirelessly-G for 7 of those hours with ConnexionByBoeing. I am hooked. I am optimistic that the hardware and airlines will eventually get it together.

    so what about cars? I virtually use my powerbook 17" 90% of the time in our van as we're travelling the country. Would a 150w inverter work fine in a car to use & charge? Or are we talking the same limits?
