I need to write section II. of a speech outline for my communications/ English class. The Main point I have already written- “The use of Cell phone charging stations in public places and venues is a trend that is swiftly catching on.” But I need to finish the rest of the outline before tomorrow morning. This section of the speech needs to be about how cell phone charging stations are increasing in popularity, and have gained popularity over the years, especially in places like airports and malls and at venues like fairs and concerts. The format is posted below. Thank You.

II. The use of Cell phone charging stations in public places and venues is a trend that is swiftly catching on.
