This cool little amplifier was designed specifically with smart phones in mind! Built into a beautiful all-wood Arturo Fuente 858 cigar box, this amp runs on a 9-volt battery and accepts input via a stanard 3.5mm stereo jack (standard headphone size jack) which almost all modern smart phones have. These little amps put out a surprisingly loud sound considering they run off a single 9-volt, and we include an adjustable Tone/Gain control to help you fine-tune the sound. These are designed and built in the USA from parts sourced from around the world.
Here are the specifications:
Box Dimensions: 6 3/4" wide x 4 1/4" high x 4 1/8" deep; Box Style: Arturo Fuente Flor Fina 858 all-wood cigar box; Amp circuit wattage: 2.5 watts; Output speaker wattage: 0.8 watts; Volume On/Off Control and separate Tone/Gain control; 3.5mm stereo input jack; Power Source: 9-volt battery.
Things to know about this smart phone amplifier before buying:
This is a real wood cigar box which once held cigars, and there may be slight variations from box to box. All of the original art remains on the box, including an illustration of a bare-breasted female on the inside lid (this is part of the Fuente Company's company seal). The smart phones and cables shown in the listing photos are NOT INCLUDED with this amp, or is the 9-volt battery. The audio connection cable that you'll need can be found anywhere phone accessories are sold, from bix box stores to Radio Shack to many sources online... many smart phone owners already have these cables, which are just basic audio cables with 3.5mm male stereo plugs on each end. Straight cables in various lengths, or a retractable type, should work fine.
This amp performs best if you turn your smart phone's output volume down to about 1/2 to 3/4 of full power, turn the amp volume all the way up, and then fine-tune the sound using the tone/gain control.
Average battery life at full volume is around 5 hours, depending on the strength of battery used.
