Public place with an outlet for a craigslist meetup?

Im selling an electronic that requires an outlet to test. I am a female and do not feel comfortable with a stranger coming into my house to test the item.

Is there a public place you recommend we can meet at for the person to test the item?

As an anecdote, there is no way for me to take a video of the item working, i do not have cables and the person is going to bring the appropriate cables to test the item in real time.
