For the price of about 20, the instrument actually provides about 2x 18 Watt RMS - Power (technical specification, according to performance data sheet of the manufacturer, belongs itself and tested), which is fully sufficient to provide with good speakers an acceptable sound in small spaces. For Discotheque sound systems I recommend to connect additional Aktivwoofer and other amplifiers)
The stereo Chincheingang is use the supplied adapter to 3.5 jack stereo port than for any standard MP3-enabled mobile device (whether the iPhone includes the like, I can not say for sure, because not tested personally swear on Android systems that are compatible and usually cheaper)
An additionally required or necessary, included with your 12V, 1A DC power supply provides the power base, even without much effort can a car 12V adapter are connected, the cables required inputs are included.
Three front side, on a chromated (plastic) base plate mounted side by side, also chromated knob (vrgl. Images) allow easy control of bass, treble and volume output level, at the back mounted through stereo cable clamps, is output.
On / off switch as forward embarked on the control panel. Nice contrast to the metallic-red aluminum enclosure, and all in mini format, kittschig and functional at the same time.
So imagine the terminal in dry rooms, cabins, tents, rooms or palaces and halls, in the automotive, motorcycle, caravan, sailors, ship, boat, anywhere just where a 12V power source with 1A DC is present, power or battery , and you want to listen to MP3 audio sources.
As said at the beginning, at the price in my opinion totally ok!
PS The as corona behind the center-mounted volume control recessed, tri-color (green-red-blue) flashing LED acts in the dark at first glance like a mini party light and who considered the play of colors in slightly intoxicated state of consciousness, will be satisfied and the music listen;)
