Planes have a 12-15 volt DC power outlet that takes an 'emppower' jack
and can power laptops etc. I have seen postings saying that Radio Shack
sells an adaptor for plugging into this empower socket, but cannot find
in the RS website, can someone tell me the item number or link to the
RS site for this, it is supposed to sell for around $8. I visited RS
store but the salesman wasn't familiar with such a thing.

Xantrex XPower® Pocket Inverter 100

$49.99 Brand: Xantrex
Catalog #: 22-159 Model: 813-0080


On the U.S. Radio Shack site.

In Canada, Radio Shack seems to have been bought up by Circuit City and
renamed 'The Source'

He's not looking for a complete inverter, only a plug adapter. And
Radio Shack does sell one of those, for about $8.

From his post, he didn't actually say he had power inverter, so I
assumed he thought that he could buy this $8 device. and connect a
standard laptop power supply to it.

The laptop runs on 12volts DC so I want just the $8 device, but I
cannot find such a device on the Radio Shack site, if anyone know the
link or part number please post it. I did a keyword search for
'airline'.

WRONG!!

Even if the laptop runs on 12 volts, you cannot just connect it to the
"12 volt bus" of a car, boat or airplane.

First, the "12 volt bus" is usually 13.5 to 15 volts.

Second, it's "dirty" and will damage the laptop.

There are two acceptable ways to run a laptop from the "12 volt"
electrical bus of a vehicle. The first is to use a suitable auto-air
inverter. Even though it may "nominally" have 12 volts in and 12 volts
out, it's still filtering and regulating the power, and in all
likelihood is a full-blown DC-to-DC converter. The second is to use a
DC to AC (110 volt) inverter and then plug in the laptops standard AC
wall power pack.

See my previous post, but I don't think that the device is offered in
the online catalog, but such a device does -- or perhaps did -- exist, I
have one. However I do not know the part number, and it may have been
discontinued.
