I had a device for my PowerBook that plugged into the car's accessory
outlet. The MacBook Pro has a different connector. Is there a car
power device for it?

apple, for some stupid reason, refuses to license the magsafe connector
so the only option is either apple's airline adapter (which they say
won't work in a car) or an ac inverter.
the airline adapter does include a cigarette lighter plug for airlines
that use that type of receptacle, but the voltage on the plane is
higher and i don't know if it really won't work in a car or if apple is
just saying don't do that. and another stupid thing about the airline
adapter is that it will only run the computer; it will *not* recharge
the battery.
your best bet is to get an ac inverter and use the normal ac adapter.
the small ones are very inexpensive ($20ish) and they should be capable
of providing 85 watts for the adapter without a problem. |

I looked at an AC inverter a while ago, and the accompanying literature
advised against running a computer on it because it does not generate a
real sine wave, but rather a stepped wave, and that could cause damage
to the computer. I don't know if this is really a concern, but it is
something to be aware of.

Considering that literally every car manufactured in the last 30 years has a
12 volt electrical system it only strikes me as incredible bozo (and
unbelievably inconsiderate) on the part of the airlines to select a different
voltage, especially given that the plug-in connector is the same as the car's
lighter socket. There are times one can only wonder!

actually, the most common plug type on airplanes is the empower
connector and not the cigarette lighter plug. however, some airlines,
such as american airlines, use the cigarette plug adapter, so apple
provides both plug types. also, a few airlines are now offering 110vac
so ordinary ac power adapters can be used.
i don't know why the airlines chose 15v instead of 12v, but i'm sure it
had more to do with being most economical voltage to supply given the
electrical requirements of the rest of the aircraft.
what's actually 'incredible bozo and unbelievably inconsiderate' is for
apple to make an airline adapter that won't work in a car in addition
to not charging the battery. >> Stay informed about: Car power for a MacBook Pro? |

Maybe it's because aircraft electrical systems over the past 80 years
have used other voltages than auto systems. Ones that I've worked with
have sometimes used several different voltages, both AC and DC, for
different systems. (Granted that one in particular was French, but
still..)
Using the same connector as that used in automobiles, on the other hand,
wasn't exactly a great idea. >> Stay informed about: Car power for a MacBook Pro? |

Many thanks for the clarifications. My recollection is that Amtrak trains, at
least on their newer equipment, tend to be equipped with standard "household"
AC plugs, so that one can connect their computer with a "regular" power
brick.

Actually, in my experience, the most common plugs in today's airlines
are either the car-type cigarette outlet or a standard AC outlet. United
and (I believe) Delta are about the only ones I've found who use
Empower. The European airlines I've flown tend to have US-style AC
outlets (which also take European 2-prong plugs).
The only real workable solution I'd found was from guys like iGo, which
create virtually an any-to-any plug environment. I got notified by them
last week that they've finally got an adapter for the MBP, but Apple
isn't working with them on a license so they can sell it. Real bummer.
I'm now trying to find out how to contact someone useful at Apple to
encourage them to license the technology.

Acela has standard 120 AC outlets at every seat. Acela equipment was
built that way. Most of the coaches used on other Amtrak equipment used
in the northeast has been retrofitted with standard outlets at every
seat. (I would say about 90 per cent of them). I don't know about the
rest of the US since I have not been on those trains. If you happen to
be in a coach without outlets in the northeast US just move to another
coach you will probably find outlets.

Some years back, when I was still living in southern New Jersey and often
taking Amtrak from Wilmington to New York City, I needed to have some power
for my Mac Laptop, and in those days such was available only at the tables in
the club car. There were probably about a dozen persons with laptops, about
two-thirds using PCs and the remainder using Macs. It was then that I noted
that the Mac users were all busy at work on spreadsheets and such and the PC
users were, perhaps all of them as I didn't notice otherwise, playing
solitaire!

i hope they can manage to license it. the lack of third party
alternatives for the magsafe is a very serious drawback, and i really
don't understand why apple is so protective over it. >> Stay informed about: Car power for a MacBook Pro? |

I take the train often on the NEC and I have noticed a substantial
increase of MacBook Pro's and MacBooks users. They seem to be
everywhere.

Hopefully you and other concerned individuals/organizations are sending
notes and letters to sjobs.RemoveThis@apple.com and/or stevejobs.RemoveThis@apple.com
asking/encouraging them to license the technology.
I've sent my notes asking them to either license MagSafe or outright
re-brand the iGo or similar product.
Apple really needs to hear from us on this. Right now it's looking like
I'll be keeping my PB G4 as my "road warrior" machine, and my nice new
MBP will be used only when I know I can be near a standard U.S. wall
outlet. This is not the solution I want, but it sure beats carrying
extra bricks.

The Coast Starlight I rode on had a single 120VAC three wire outlet in
our sleeper. I had brought along a three way adapter to power both the
laptop and my scanner. I would recommend a short AC extension cord (1
ft) or a real compact power strip. The way the outlet is set into the
wall the three way adapter with power adapters in it tended to fall out
of the outlet (it couldn't quite plug in fully).
