Continental AC power outlets in coach.
I was impressed to find AC outlets under my seat in coach on Continental
(737) yesterday (HOU-SFO). No funky EmPower or 12V cigarette lighter jacks as on some carriers. It appears as if they have inverters on every row, as the aisle seat now has some sort of box under it which severely restricts foot room and storage room (you can't even slide a small day pack under the aisle seat any more). I suspect that that box contains a 24VDC to 110VAC inverter (airplane low voltage DC wiring is 24V). There are two outlets in each row, on either side of the center seat so everyone can reach them. I guess it'd be a good idea to bring a triple tap just in case all three passengers wanted an outlet. No audio or video system at all on these 737s which appeared to be pretty new. Maybe next flight I'll bring a Zelco Brisk Brew coffee maker and brew my own coffee on board. "http://tinyurl.com/zelcobriskbrew". |

... I was impressed to find AC outlets under my seat in coach on Continental (737) yesterday (HOU-SFO). No funky EmPower or 12V cigarette lighter jacks as on some carriers. That's something I haven't seen yet. I usually find the "cigarette lighter" type. It appears as if they have inverters on every row, as the aisle seat now has some sort of box under it which severely restricts foot room and storage room (you can't even slide a small day pack under the aisle seat any more). I suspect that that box contains a 24VDC to 110VAC inverter (airplane low voltage DC wiring is 24V). Most of those "boxes" under the seats contain life jackets for water landings. There are two outlets in each row, on either side of the center seat so everyone can reach them. I guess it'd be a good idea to bring a triple tap just in case all three passengers wanted an outlet. Most aircraft outlets are for low power draw. Ganging up on these outlets may overload them & blow a circuit breaker. No audio or video system at all on these 737s which appeared to be pretty new. Maybe next flight I'll bring a Zelco Brisk Brew coffee maker and brew my own coffee on board. "http://tinyurl.com/zelcobriskbrew". Yeah chuckle bring a Hibachi too, and grill up a couple of steaks. |

It was a sealed aluminum box about 6" wide, and the full height of the under seat food space, extending the full length of the seat. Rather annoying to lose that foot space. Most aircraft outlets are for low power draw. Ganging up on these outlets may overload them & blow a circuit breaker. I think it's at least 350W per each pair of AC outlets because some of the notebook power supplies now are drawing 150 watts, and they need some margin, but most of the laptop supplies draw only 65W-90W so three of them could be used without overloading the inverter.

However, in my situation, I don't see this too much. Although I'm Platinum with CO, most of my flights are on RJ's. It's the bare minimum. I would love to see them install USB outlets. All my entertainment toys can run off the USB ports, and charge at the same time. Maybe next flight I'll bring a Zelco Brisk Brew coffee maker and brew my own coffee on board.

Not necessarily -- as I understand it, the limit is often closer to 75-100 watts per outlet, and some people have found that they can't charge and use their laptop at the same (it cuts off the AC power), and have to remove the battery (so it won't charge) to use the laptop. bare minimum. I would love to see them install USB outlets. All my entertainment toys can run off the USB ports, and charge at the same time. Delta has USB ports on the 777s at least (and I believe they have them at all rows, while the AC power in Coach is only in the first ~10 rows). Josh |

CO will be configuring them with LiveTV (DirecTV) |

The 110v systems I've used on aircraft are severely current limited - to the point where on one flight I had to remove the battery from my laptop to get it to work as the charging circuit bumped up the drain enough that the breaker would trip. |

" That's barely enough to power one laptop without a battery, much less three. |
