The PicoBoo AC (previously named PicoBoo 105) comes with an AC power cable, not a power supply.

Each outlet on the PicoBoo AC can handle 10amps of load.  For reference, a standard 100watt light bulb draws about 1amp.  A solenoid about .07 of an amp.

The audio amplifier inside of the PicoBoo AC is rated at 30watts.  However, it realistically can output around 15watts of power to car speakers, horn speakers, and such.
