I am surprised there’s not more demand for regular 110V or USB-based charging stations on everyday municipal trains and buses. Sure, average transit times are about 30 minutes so the need for charging isn’t that great. Maybe, everyone who commutes is really smart and makes sure to charge their phones before jumping on the bus. But non-commuters and visitors would appreciate having one to two outlets per 25 seats.
Nearly all, if not all, of the major intercity bus operators in the states claim on their websites to have electrical outlets on buses in their fleet. Time for local public transit agencies to think bigger when ordering new buses and trains.
