This is the most powerful Mighty Dwarf vibration speaker. There is no battery - the unit must be plugged in to operate. The external amplifier connects directly to the sound source through an earphone jack. There is no microSD card reader or Bluetooth interface with this speaker. This is an ideal speaker for a permanent, powered installation such as a home theater or work station sound system.
26 watts of power! This tiny speaker delivers a wallop of sound from a tiny 2 inch by 2 inch desk foot print. The wired connection to the power source provides the continuous electricity to deliver ongoing, momentous, sound. The unit comes with a universal, North American standard, two-blade wall adapter. This adapter can be plugged into a 110 - 220 volt AC to step the power down to the 18 volts needed for the amplifier. The external amplifier has an on/off switch as well as a volume up button and a volume down button. The sound controls on the sound source - iPod, laptop, PC - still operate and can control the sound volume as well. 20 Hz to 20 kHz Frequency Range
