Need your batteries charged? Airports offer fliers more help

— -- Ken Tichacek has become expert at finding places to recharge his laptop and iPhone at airports.

He's commandeered a check-in counter at an empty gate. He's unplugged a water cooler and perched next to it. He's seized an electric outlet in the middle of a boarding lane for another flight.

"I held my ground as passengers stepped over me to board," says the Salisbury, Vt., Road Warrior and management consultant.

Such fervor is common among frequent business travelers, who twitch when they can't tap on their tablets or smartphones because batteries are drained. Walk through any terminal and you'll see people plugging electronic devices into any outlet they can find, even if it's behind a bar or in a bathroom.

Airports and some airlines understand the needs of today's digital travelers and increasingly are making electrical outlets more available.

"Airports recognize there is a demand for power … and have attempted to fill this need through innovative approaches, such as providing charging stations at old payphone banks," says Morgan Dye, senior manager of communications and marketing for Airports Council International-North America, which represents airports in the U.S. and Canada.

Responding to a growing need

In a survey in 2010, the council found that 56 of 89 airports reported having electric charging stations for passengers. And, the group says, the number is growing, with airports in San Francisco, Nashville, Oakland and other cities adding stations. Among them:

•Phoenix Sky Harbor International Airport recently added 240 electrical outlets and 204 USB ports throughout the airport. Those improvements include 36 new sets of padded chairs, each with a table in between with two outlets and one USB port.

•Seattle-Tacoma International Airport has added more than 114 plug-in charging units to seats over the last few months, each with two plug-ins. Another 300 will appear before the end of the year.

•Las Vegas-McCarran International Airport has promised that its new $2.4 billion Terminal 3 expansion, which will be ready by June 27, will have outlets scattered over the floor near seating areas. The airport plans to add more seating-area power sources at its busy C concourse, too.

Many airlines — such as US Airways, Delta and Virgin America— also are adding electrical outlets in some of their gate areas at some airports, although they say they're only tenants, and that providing charging stations is the responsibility of the airports.

Power struggles can get ugly

More electrical outlets can't come fast enough for many frequent business travelers, some of whom say they've seen arguments and even fights break out over access.

Avi Rosenthal says he saw two men come to blows because there was only one power outlet to recharge their dying iPhones at Los Angeles International Airport. It was late and the flight was delayed, enough to rile up the cranky crowd.

Rosenthal, a technologist in Harrisburg, Pa., has tried to avoid such extremes by carrying a fold-up six-outlet power strip in his carry-on. Not only does he get to recharge his devices, but he also helps his fellow travelers.

"I take it everywhere," he says. "I then get to play the hero."

Debra Martin, a safety consultant in Kent City, Mich., once got into an argument at an airport with another traveler who was using the only two outlets available in their gate area.
