Laptop on a Long-haul Flight...
Hi,
New to the laptop world of gadets, tips and tricks. I am bringing a laptop on my upcoming long-haul flight and wish to watch a few 2 hour typical Hollywood movies on it. My laptop battery only allows for 2-3 hours max. However --- I hear that there are chargers that allow you to charge your laptop on the aircraft seat socket? Is this true and any recommendations on the best of the best out there? I will be flying a combination of Continental/Swiss/AA airlines if that helps. Thanks. p.s. I'd rather not have to buy a 12-cell battery, since that would kill this rather light and mobile laptop! But if that's the only choice...... |

I will be flying a combination of Continental/Swiss/AA airlines if that helps. Here is a site that shows which aircraft have power ports, and what type they are. http://seatguru.com/ You will need to look at the current schedules, and determine what type of aircraft you will likely be flying in, then look at that particular model on the above site. In short, Swiss only has power ports in business and first. None in economy. American and Continental have them on their long-haul aircraft, at all seats in the premium classes, but only at some seats in economy. Look also in the "Travel Resources" menu on the left of the page for a discussion of the various types of connections. You might need to obtain a special charger to use the power ports. |

I will be flying a combination of Continental/Swiss/AA airlines if that helps. As others have said, check "setguru.com" for specifics on your airline. Some seats differ in the type of power provided. Some have "AC" power, some have something called "EmPower" (CO has this). Make sure you have an adaptor that can handle the type of power your seat provides. Also, make sure you fly an aircraft where the laptop port power is offered (CO generally offers it on it's 777's and 767's for all BF seats but only a limited # of coach seats). Another important factor is how much power your laptop draws. These seats (under Empower especially) usually only put out 70watts. Be sure your laptop doesn't draw any more than that or it may not work. Sadly, my laptop draws 160 watts @ 19.5 volts DC (it's a huge 17" Vaio) and so for most Empower adaptors like the "Juice-70," it fails - it won't even power up. I'm actually thinking of having to get a smaller one just for air travel. I can't seem to find an adaptor that will convert properly. Finally, understand that using a laptop in flight can be seen by some FA's as a safety risk (not necessarily from a "terrorist" angle, but more "turbulence" angle). On my most recent long haul flight, I seemed to have drawn "Atilla the FA" who constantly reminded me that at the slightest hint of turbulence (ie. when "fasten seat belt sign is turned on), I would have to pack up the laptop and put it away. Each and every time!!! Not very conducive to watching a 2 hour movie.... sigh ____________________________________________ Regards, Arnold |

You can buy an adaptor that will fit in the airlines sockets, providing the aircraft *has* the sockets available. You'll probibly have to check with the airline, although someone else in the group may have more knowledge on the subject. Some airlines have standard 110v outlets that take a standard power cord. Others require the use of an "Empower" cord which comes in 3 or 4 versions, some of which look like a miniature cigarette lighter plug. One thing you should keep in mind is that most seat systems do not provide enough current to operate the computer with the battery installed. The charging circuit will overload the outlet and trip the breaker. |

The charging circuit counts for a large part of the current the laptop draws. On a recent Lufthansa flight, I had a bunch of people asking me how I was able to operate my laptop for the better part of the flight when theirs kept dying. |

I have seen adaptors though that put out 140 watts with an Empower source, and maybe removing the battery with one of those might just work. Worth a try anyway. ____________________________________________ Regards, Arnold |

I'm actually thinking of having to get a smaller one just for air travel. I can't seem to find an adaptor that will convert properly. I saw this "laptop to laptop" varition occur personally last month: the guy sitting in the row with me had been on a series of flights and was running out of juice, so he bought the Empower adaptor off of the "In flight Duty Free" cart. He proceeded to plug it in, get a green status light, etc, but the thing would trip as soon as he plugged in his Dell. In trying to troubleshoot the device (to see if he had gotten a defective adaptor), we plugged in my IBM laptop and the system worked fine. The tyrrany is that we checked through all of the specifications and his Dell *should* have worked (being 70W), but still did not. Perhaps the battery charging was the underlying issue, but we didn't know that trick at the time. Overall, I see the Empower jacks as a good idea, but one that was poorly implimented, since it does seem that too many people have problems. And considering that products such as the "iGO" are relatively heavy copper/iron transformer bricks, in some circumstances, you're probably better off buying/carrying a second battery pack. -hh |

True, but consider what they were up against: A retrofit solution for a fleet of older aircraft that have a limited amount of current to share with 150 or more seats. Ideally it would have been good if they could have provided a 2000w 110v jack at each seat, but that leads to people trying to run equipment that isn't allowed ("What's wrong with this space heater, I'm cold!) Although some airlines have current limited 110v jacks, by going with Empower, they at least control the users to those who might have some understanding of the limitations. I suspect newer "all electric" aircraft like the 787 will have much more capability in this area. And considering that products such as the "iGO" are relatively heavy copper/iron transformer bricks, in some circumstances, you're probably better off buying/carrying a second battery pack. Very true. |

this rather light and mobile laptop! But if that's the only choice...... If you do have to go this route, keep in mind you'll get much better battery life if you 'rip' the movies to your hard drive and watch them from it, as opposed to just putting a DVD in your drive - The DVD will spin continuously for 2 hours and eat up battery life like nobody's business. Also, if it's a PC-laptop you can go into the bios and adjust the backlight settings, which will extend your battery life. The other thing to keep in mind is if you're in economy you may not have seat pitch space to watch a movie anyway. If you're in economy and the person in front of you reclines you'll barely be able to open a paperback book, much less a laptop. At least that's been my experience with my laptop. Finally, you may want to shop for some good headphones, or get a "Boostaroo" ( http://www.boostaroo.com/ ) - A number of the laptops I've had over the years (Toshiba & Dell to name two) simply didn't output a 'loud' enough signal out of the headphone jack for me to hear a movie clearly - It needed to be further amplified. A good test would be to put the headphones on and watch a movie on a city bus at rush hour. If you can hear it you should be fine. Cheers, Geoff Glave Vancouver, Canada |
