    Inflight power for laptops

    I just asked our IT experts if they have any of these new-fangled cables that allow you to connect to an airplanes' in-seat power supply (those airlines that offer this, that is). Apparently we don't have any and they have asked me if I have any info, particularly if you need a different cable for each airline, or if there is one standard out there.

    I've tried googling for this, and I've ended up with lots of different manufacturers, but haven't been able to discern if they all use the same technology, plug etc. etc.

    Anyone have any advice that I can pass along?

    Hi Bowlie,

    Sorry I can't help you with this but I think the best bet is to just call the particular Airline (s) you'll be using and see if they can shed some light on this. As you said, not all even offer the power outlet at all. I have never had the occasion to have to use them.

    Re: Inflight power for laptops

    Is it a PC laptop or a Mac laptop? (Does Apple do laptops?)

    John

    PS the provision of in-flight power sockets may depend not only on the airline, but on the Class in which you are travelling. Since you can afford an Apple Mac that must be First Class, or higher! Aren't you hiring your own private jet??!

    Re: Inflight power for laptops

    Hi Bob!
    <img src=/S/thankyou.gif border=0 alt=thankyou width=40 height=15> for the reply. My 3 year old Dell laptop gets maximum 2 hours on battery, and this is getting shorter and shorter all the time. I've been using the lowest power settings as well. Have asked for a new battery, but apparently they are in short supply or something. I seem to just get started on something and run out of juice.

    The airline contact people have "no clue" but I found this on British Airways web-site:
    <hr>The first is a DC based system. The system provides +15VDC and is capable of delivering 75 Watts of power via a hypertronics connector mounted at the seat. For information, our entire fleet of Boeing 747 aircraft (Jumbo Jets) have been installed, and over half of our Boeing 777 aircraft installed. (we expect to have 100pct of our 777 aircraft fitted by the end of summer 2004).

    To use the DC system, there are a number of adaptors available commercially that come supplied with the correct connector for the seat. The adaptor BA recommends, and one that has been tested for use on board aircraft, is the new DC to 110 VAC Inverter made by Teleadapt. British Airways sells this model on board. The Teleadapt adaptor delivers 110V AC via a standard 2 or 3 pin US or European socket making it universal. The Teleadapt unit allows the customer to plug in their standard lead.

    The second is an AC based system. We have fitted 10 of our new in-service A320 aircraft with this AC based Next Generation PC power system. This system features a US/Euro style 2/3 pin socket delivering 110V AC fitted to all Club Europe seats. This system allows the customer to plug straight in without the need for special adaptors.<hr>

    Seem silly that their seat delivers 15v DC for which I need an Inverter to convert it to 110V AC to plug in my powerbrick to convert it to 20v DC. The inverter also costs GBP90 (USD160 - CHF210). At that price I'm not going to buy one, but was hoping my organisation could provide one for me to use. But if every airline is different ...

    Their AC system is much better - but if they only have in on 10 of their short haul aircraft you would never know in advance if you could use it or not.

    Any other loungers (other than John Gray) have any personal experiences?

    Re: Inflight power for laptops

    Hi John,
    Have you been away? Haven't had any disparaging comments from you in a long time <img src=/S/exclamation.gif border=0 alt=exclamation width=15 height=15>. No my Mac is a desktop, and the airlines might consider it to be just a little too big to take on an aeroplane. My organisation is not Mac-friendly (probably the nicest comment I've heard for some time) and I have a Dell (somthingorother mark II).

    Would be nice to have one of the new iBooks - and $1099 isn't exensive for a laptop particularly one that gives you 6 hours (ok 'your experience may vary') of power. Probably costs more in the Excited Kingdom - VAT and all that you know, frightfully. Even the bigger ( <img src=/S/groovin.gif border=0 alt=groovin width=21 height=21>) powerbooks are competively priced. Lets face it Apple isn't the cheapest, but offers (one of) the best value for money.

    OK,
    Since you concede that Apples are better value than non-Apples, I apologise for your misunderstanding of what I was not trying to say.

    You're welcome. <img src=/S/evilgrin.gif border=0 alt=evilgrin width=15 height=15>

    Re: Inflight power for laptops

    Isn't this it? <img src=/S/aussie.gif border=0 alt=aussie width=21 height=22>

    (As in that old joke where an Londoner want's an operation to relieve his stress level etc. etc. and the doctor has a solution, have 1/4 of his brain removed and turn him into a Bristolian (or whatever). After the operation the Dr is there when he wakes up. "I'm so sorry" says the Doctor, "we made a terrible mistake. We've removed 1/2 of your Brain". "That'l be allright, mite" says the ex-Londerner; "Got a Fosters?")

    Re: Inflight power for laptops

    Going back to the original topic of the thread....................
    All of that confusion is the result of the LACK of standardization in not only the computer industry but in electronic devices in general. None of the major manufacturers wish to get together and agree on things like STANDARD power specs. Not even among international organizations like IEEE, is there any attempt to come out with ONE "do all" device. Why must there be multiple voltages, current and even types of power connectors and plugs? ( because if you buy a device from company "A". they don't want you to buy an accessory from company "B" )

    In the meantime, charge up your laptop to the max before your trip or plan your flights that are longer than 2 hours to have a stopover (s) every 1 3/4 hours?

    BTW, Seriously now, as with any older rechargeable battery, it is good practice to occasionally run the batteries all the way down to nothing, then do the recharge. These batteries develop what is known as "low voltage memory" if they are recharged numerous times without running them down to zero. Newer packs don't have that condition. The low voltage memory will result in a condition that will only charge a pack up to that lower voltage and you could charge it for days and not have it exceed the lower voltage point. ( shorter useable life that you describe )
