SHARP AC adapter EA-57A, 9.8V DC output, 1.2A, capable of supplying 23W of power. - Brand: SHARP - Model: EA-57A - Input Voltage: 120V AC - Output Voltage: 9.8V DC - Output Current: 1.2A - Power Consumption: 23W - Country of Manufacture: Japan This is an AC adapter for a device I used when I lived in the US. I'm sorry, but the output terminal is broken as shown in the photo. It's quite large, measuring approximately 10cm (height) x 7cm (width) x 6cm (depth). When used with 100V in Japan, the output voltage will be approximately 8.1V.
