  Power Cord Note: Little Dot amplifiers ships with a standard Type-B power cord (American 3-pin or U-ground) suitable for use in areas such as North America, Japan, Taiwan, etc. If your country's outlets use other power cord types (ex. Schuko) you will need to provide you own power cord. You likely have several spares around your home, as any standard power cord (like your computer's power cord) will work perfectly fine. We do apologize for any inconvenience!
