I always wondered why there weren't more plugs and outlets by airport terminals? I guess it was to leave room for sponsors to pick that up. Yesterday, I was at Newark, terminal C112, and I saw one of these Samsung Charing Stations:

Charging Station

It seems to have been installed at Newark in late August:

Samsung Telecommunications America (Samsung Mobile) today announced the installation of 50 charging stations at Newark Liberty International Airport (EWR). The charging stations have been installed throughout Terminals A, B and C.

I think it is a great branding move. You see banner ads all over airports, but for people with dead cell phones, this is a memorable piece, at least for now.

These charging stations are at other airports also including 54 stations at John F. Kennedy International Airport (JFK), 51 stations at Los Angeles International Airport (LAX), 12 stations at LaGuardia Airport (LGA), 18 stations at Orlando International Airport (MCO) and 22 stations at Minneapolis-St. Paul International Airport (MSP), along with eight Samsung Mobile Travel Centers at Dallas/Fort Worth International Airport (DFW) and others.
