This is the Providence Battery Emulator 9.6, a standard AC adapter. It maintains a voltage around 9.6V, allowing it to reproduce the same sound quality as battery operation. Please check the photos for the crack on the corner. For deliveries to Hokkaido, Okinawa, and remote islands, air transport may not be possible, and delivery may be by land. *We have confirmed that it powers on before listing, but we cannot provide support for defects after arrival. Thank you for your understanding.
