In previous question i meant do charter buses have...?

Question

cigarette lighter adapters!!! for like cell phone chargers.

Answer 1

Most charter buses have a 12v adapter in the driver cab area. In terms of public use, that is entirely up to the company and driver.

The company I drive for has not only 12v but also a 110 station in the rear of the coach for passenger use, as well as a CD burner for digital pictures.
