By Friday at McCarran International Airport, a couple of thousand outlets and USB ports under seats and inside bars and restaurants will be available for those looking for a power charge in Terminal 1 before heading home after the gadget convention.
The airport had already installed free airport-wide Wi-Fi ahead of the electronics show 10 years ago at a time when travellers had either a laptop or personal digital assistant, if that, and were at most checking e-mail or finishing up a PowerPoint presentation.
Now, there are movies to stream, virtual meetings to conduct, Internet games to play and books to download. More than 160,000 people attended the 2014 show, which takes over the Las Vegas Convention Center, the Sands Expo and several nearby hotels with more than 2 million square feet (190,000 square meters) of exhibit space.
Hot trends this year include Internet connectivity in everyday products such as cars and appliances and the growth of online video as an alternative to traditional television channels. New TVs with sharper images and better colours are also expected. The four-day show begins Tuesday, though pre-show events take place Sunday and Monday.
Karen Chupka, senior vice president with CES and the Consumer Electronics Association, said her group is likely the biggest electricity and Internet user when it comes to town.
"We tend to push the limits of everything," she said adding that year after year, the city has beefed up its capabilities in response, such as relatively recent Internet upgrades to the convention centre that show organizers are particularly excited about. The airport's addition of a couple of thousand more outlets and USB ports is, "great, that's absolutely wonderful," she said.
Travellers with gadgets often face a dilemma to grab a bite to eat in a restaurant or bar lacking outlets or slump against a wall, plug into a wall outlet near a boarding gate and watch as the battery is recharged.
"You don't have to make that choice," said Samuel Ingalls, assistant director of aviation information services at the airport.
The 500 under-seat power supplies with two outlets and two USB ports each and more power outlet upgrades to come are expected to cost the airport $400,000 (roughly Rs. 2.5 crores).
The new Layover Bar in the airport's pre-security area, though, features outlets under the counter at each seat. Each table at the new neighbouring Wendy's has them, too.
Walls of unused payphones in a terminal that got its start in 1963 and was expanded in the 1980s were replaced years ago with counters, stools and outlets for recharging zones but it hasn't gotten a true outlet boost until now.
Terminal 3 debuted in 2012 with integrated under-seat outlets and charging ports in restaurants and bars.
More outlets for charging comes as airport officials have also boosted the bandwidth giving travelers - and there are more than 3 million arriving and departing passengers a month - twice the download speed.
