Many devices (e.g., computer-TV DVD) USB ports output stable voltage and current, and filter some bad waves. So the DAC (Digital to Analog Audio Converter) will work better and the decoding will be more stable. In addition, using USB power is more environmentally friendly, reduces costs, and is beneficial for the entire country. This item does NOT convert Dolby. Due to the difference between different monitors, the picture may not reflect the actual color of the item. Please understand, thank you.
