Phone Charging at Airports, Train Stations and Transit Hubs: The Wait-Time Math

Yes, a transit hub is one of the best places to put a phone charging amenity, but the pitch is not the one a bar or a shopping mall makes. In retail, longer dwell time is something a venue chases because the customer chose to be there and can leave whenever they want. In a terminal or a station, dwell time isn't chosen. A passenger cannot decide to come back tomorrow once a gate is delayed. Almost everyone waiting is carrying the exact device that wait depends on: 83% of air travelers carry a phone, 60% a laptop, and 44% already travel with their own power bank, per IATA's own passenger survey. That leaves a majority who don't, and that gap is the real opening.

A forced wait is a different pitch than a discretionary one

Brick's own research into bars and shopping malls found that dwell time and spend move together, but that logic assumes the customer chose to be there and could walk out at any point. A transit passenger can't. Once someone clears security, they are committed to that terminal until boarding, whatever happens to the flight. Harvard's Graduate School of Design has tracked where a passenger's terminal time actually goes: roughly 4% is spent actively working through steps like check-in and security, and another 25% or so is spent standing in the queues to get to those steps. That's close to a third of total terminal time that isn't free in any real sense, it's required. What's left, researchers call the "golden hour," the roughly 60 minutes after security when stress drops off and passengers are most likely to shop, eat or otherwise spend. A charging amenity belongs in that window too, not as a nice extra, but as one more thing standing between a stressed passenger and a calmer one.

The wait-time math: what the data says

A 2024 study of dwell time at 89 U.S. airports, published in the Journal of Air Transport Management, found that a 10% increase in dwell time produced a 5% increase in non-aeronautical revenue overall, split unevenly: 8% more in food and beverage, 6% more in retail (Wu, Morlotti and Mantin, 2024). Airports already treat that golden hour as revenue they've paid for in terminal space and retail leases. A dead phone during it doesn't just annoy a passenger, it takes a browsing, spending passenger and turns them into someone standing at a wall socket instead, which is time the airport built the terminal to sell and didn't get.

Why a dead phone hits harder in a terminal than a bar

LG's "Low Battery Anxiety" survey found that nearly 9 in 10 people panic once their battery drops to 20% or lower, and that panic doesn't fade in an airport, it sharpens. A phone at a bar is how someone texts a friend. A phone at a gate is the boarding pass, the gate-change alert, the translation app at passport control, and the rideshare booking the moment the wheels touch down at the other end. The same improvising Brick has already documented at bars, where guests order a drink just to reach an outlet, shows up in terminals as passengers camped cross-legged by a wall socket or fighting over the two working plugs in a bank of forty gate seats. It's the same demand, just with higher stakes attached to losing.

What a self-service station changes at a gate or platform

A fixed outlet rewards whoever got there first and can sit still the longest. A powerbank sharing station doesn't work that way. A passenger uses tap-to-rent at the station's card reader, pulls a charged powerbank from a slot, and keeps moving, boarding or working the terminal while it charges, instead of standing sentry over one wall socket. That matters more here than almost anywhere else a venue might install one: a delayed departure or a last-minute gate change doesn't strand a charging phone at the wrong end of a terminal, because the powerbank travels with the passenger instead of being tied to one plug. A single cable taped to a pillar can't do that. Handing a phone to a gate agent to charge somewhere in the back can't either, and it introduces exactly the custody problem no traveler wants when boarding is called with five minutes' notice.

Where this earns its space in a terminal

The natural spots follow the forced-wait logic rather than copying a mall floor plan: just past the security golden-hour zone, at gate seating banks on long-haul or delay-prone routes, in arrivals and baggage claim where travelers are reconnecting to a new network and calling a ride, and just as directly on train platforms and station concourses, where infrequent or delayed services can turn a ten-minute wait into an hour with no warning. None of this describes an existing Brick deployment inside a terminal today; this is the case for treating transit hubs as their own vertical rather than a smaller version of the mall pitch, the same way Brick has made the case for tourism-heavy venues without claiming a specific station that doesn't exist.

FAQ

Is airport phone charging really a different case than a bar or mall?
Yes. Dwell time in a terminal isn't optional the way it is at a bar: a delay, a queue or a gate change keeps a passenger there regardless of what they'd prefer. The revenue relationship between dwell time and spend still holds, but the reason to install charging shifts from "keep them here longer" to "make an unavoidable wait less miserable."

How many air travelers already carry a backup battery?
44%, according to IATA's own passenger survey, alongside 83% who carry a phone and 60% a laptop. More than half of travelers are relying on whatever charge they left home with.

What does the data actually say about charging and airport spending?
A 2024 study of 89 U.S. airports found a 10% increase in dwell time produced a 5% increase in non-aeronautical revenue, with food and beverage and retail both rising. A dead phone converts spending time into socket-hunting time instead.

Does a flight delay make the case for charging stronger or weaker?
Stronger. A delay is exactly when a phone charged for a 90-minute layover runs flat, and passengers who planned for a short wait start actively hunting for outlets instead of browsing, eating or resting.

Where should a transit hub actually place a charging station?
Past security in the low-stress "golden hour" zone, at gate seating banks on delay-prone routes, in arrivals and baggage claim, and on train platforms or concourses serving infrequent or delay-prone services.

For an operator already weighing whether a station network makes sense for a transit site, brick.tech walks through how the tap-to-rent, return-anywhere model works day to day, worth a look before assuming a terminal needs the same setup as a food court.

A missed connection isn't evidence a charging station failed. It's the exact scenario the whole pitch is built for, because on that day, nobody waiting has the option to just come back tomorrow.
