Dimension: 77 x 55 x 22 mm Package list: Note: Please confirm your model before payment. With AUX package included: -1 x Digital to Analog Audio Converter with AUX 3.5mm Jack; -1 x USB power cable; -1 x User Manual; -1 x Optical cable (Toslink cable); Note: -Do not use other plugs, it can only use voltage: 5V, current: >=1A plug -Remember to set the audio output to PCM or LPCM as it is not compatible with 5.1 channel signal -This item does NOT convert Dolby. -The reason to cancel the external power adapter and use USB power. Many devices (e.g. Computer TV DVD) USB ports output stable voltage and current, and filters some bad waves. So the DAC (Digital to Analog Audio converter) will work better, and the decoding will be more stable. -Besides, use USB power that is more environmentally friendly, and reduce costs, and compatible with all countries
