Includes speaker and power cable. For testing purposes, I powered on the speaker, connected it to Google home app, asked Google a question, played music, and reset it. Serial number will vary on each unit. Speakers are in good cosmetic condition similar to one shown. I have a few available if interested in multiple send me a message. If you don't need the power cord, I can refund/reduce $2 (message me before shipping). Items shipped next business day. Thanks for looking!
