HOBOKEN — A dead cell phone is similar to being marooned —surrounded by a sea of functioning bright screens, but severed from the handheld outside world.

At a bar, a phone without power can complicate meeting up with friends or taking down  the phone number of a prospective date. Some bars in Hoboken have introduced a solution: mobile phone charging stations.

Scotland Yard on Hudson Street has a CNG Systems kiosk, which can charge up to six different phone models. Sasha Dash, co-founder of CNG Systems, said that the units help keep patrons at the bar, since it’s increasingly difficult for people to go phone-less for an extended period of time.

If a patron’s phone dies, they won’t necessarily feel compelled to go home if they don’t have a charger on hand.

“We all feel naked when we don’t have our phone on us,” he said. “The benefit really is having that access to your life.”

A one-hour charging session costs $2. Since the phone isn’t locked into the unit, it shouldn’t be left unattended, Dash said.

Dash said that CNG is also launching a mobile charging unit, the “pocket rocket.” The lipstick-size battery pack will be sold at convenience stores, fully charged and ready to power-up a cell phone. He said CNG also hopes to introduce its charging units at other bars in Hoboken.

Whether or not the pay-to-charge stations catch on at other bars in the city, there seems to be something to providing access to power.  Leslie Migliaccio, a bartender at the Shannon on First Street, said that iPhone 4 and 5 chargers are kept behind the bar. The bar also has a ChargeAll charging station, but only one of the  wires connected to it functions, Migliaccio said.

Having cell phone chargers on hand becomes particularly useful on Sundays, Migliaccio said, since several patrons will spend all day at the bar watching football games.

“It’s good for us too,” she said. “It makes them feel like we’re concerned about their needs.”
