Review: Good - Good Review: Value for money DC Power Adapter - I purchased this DC power adapter for making an audio system. I made an audio system with a Pioneer Car stereo (Old one with CD and USB) and Sony 2 channel Subwoofer amplifier. Both are designed for car and required to be powered by 12 volt DC power source. I purchased this DC adapter and it is powering both the car stereo and the amplifier. No problem till now. I have tried the same with 4 other similar projects. It is wonderful. No hissing noise or disturbances. Even with full amplifier gain it works remarkably. ## Features - 12V DC , 400W, 33A OUTPUT - INPUT VARIES 187 V TO 262 V AC, 50HZ - "N" & "L" line on the sketch map means the neutral line and the live line. - " E" is for Earth line, "+" is outgoing positive pole, "-" is outgoing negative pole. - The place on the wire connecting is the air outlet of the cooling fan.
