If this is a simple bedroom system with headphones or cheap computer speakers, you may opt to use the motherboard's stock headphone plug or the laptop's built-in speakers.

This would be enough to power an electronic speaker or small LED (light-emitting diode) lights, but not enough to operate a laptop, which requires an estimated 30 to 50 watts.

There’s also an auxiliary jack that lets you use the iMainGo X as an external stereo speaker system for any device with a 3.5 mm connection -- laptop, cell phone, electric guitar, you name it.
