This is the Bose S1 Pro (older model) portable PA system. There is a dent on the speaker grill, but it does not affect the sound performance. It is a battery-powered model, but there is an issue with the original battery pack, and it cannot communicate information with the main unit. It seems to function as a battery, but since the charge level is unknown, I have recently been using it with the battery removed and connected to the power cable. The last day of use was October 19, 2025. Although not pictured, a power cable is included. Please download the manual online if needed.
