Passengers on Contiki tour buses can now relax and enjoy their travels without stressing about their mobile phones, digital cameras, iPods or other portable electronic devices running out of juice. Australian-based Contiki has introduced Charging on the Go as a free service to customers. Starting this summer, the company is outfitting all of its European coaches with electronic charging units, so customers can plug in while en route to their destination and not have to worry about their batteries going flat. This is a smart move considering how much people increasingly rely on digital devices, especially while travelling. It adds an extra layer of convenience for customers—and should be particularly appealing to the Gen X and Gen Y crowd that Contiki primarily caters to. Every business serving consumers in transit can win their approval by helping them stay wired, connected and powered. Related: Charge lockers.
