Ask Elizabeth: Converting to USB to save on outlets & Bluetooth on a plane

by Elizabeth Blair York | July 13th, 2007

Q. One of my big problems with all these cords? There aren’t enough outlets to plug in everything when I’m on the road. How do you handle this?

A. Well, I have to start by saying that the MoGo mouse does, of course, charge in the PC card slot.

Have you thought of converting to using a powered USB hub instead of power cords? Obviously, you always have to carry the adapter along with your laptop. But if you buy a portable USB hub, you can use it to recharge your cell phone, your PDA, your iPod, external hard drive or storage… frankly, most every business gadget I can think of.

It’s a little slower than plugging directly into a power outlet, but the cables are much more manageable.

And converting to using USB can be a lifesaver if you are traveling by car a lot and for on-sites where outlets are at a premium.

Just remember that the USB hub you buy should be the kind that needs an outlet. (Yes, a cord.) The non-powered ones aren’t usually strong enough to charge things. And you will want to test it before your next trip.

Good luck.

Q. I want to use my Bluetooth headset on a plane to listen to movies on my laptop. One airline says I can’t, a flight attendant on another said it was fine once in flight. Is it?

A. That’s a great question. The answer is not clearcut. In fact, what devices are legal on commercial flights has been topic of heated debate for years. (Phones, PDA’s, iPod’s, etc.)

My simple response has always been - do what the Flight Attendants tell you.

But if you’re truly curious about the law, then here’s the more complicated response.

The use of electronic devices on planes is actually governed by several organizations, chief among them the FAA (Federal Avaiation Administraion) and the FCC (Federal Communications Commission).

The FAA says, basically, “no portable electronic devices during take-off and landing and at the pilot’s discretion otherwise.”

The FCC restricts what bands can be used (such as those used by Bluetooth ). Unless the FCC has applied restrictions to the band, the decision is back in the hands of the pilot and flight crew.

Bluetooth’s official website doesn’t speak to the issue.

Most people, like the fictional Toby on the West Wing pilot episode, can get pretty frustrated by the seeming inconsistency of the rules and application. “We’re flying in a Lockheed eagle series L-1011. It came off the line 20 months ago and carries a Sim-5 Transponder tracking system. Are you telling me I can still flummox this thing with something I bought at Radio Shack?!”

If you feel that way, too, may I recommend a little light reading? Or: FAA rules regarding electronic devices
