Most of these were designed for the 5 volt Amp/Bluetooth units that I build except for the Whammer-Jammer with all of the LiPo's and the Lepai. It operates at 12 volts and the Bluetooth unit operates from a separate 5 volt bank battery. All totally portable and will operate for many hours on battery. Connect via Bluetooth and yer jammin'..
Took the Whammer-Jammer to the drive-in. Everyone around me turned their junk off.. LOL..
Here's some pics on ImageShack. Note that I moved the same Amp/Battery/Bluetooth around to most of the other speakers..
