Add some extra boom to your audio project with these USB powered loudspeakers. We sampled half a ton of different models to find ones with a good frequency response, so you'll get quality audio output for music playback! There's even a volume control wheel on it so you can set it up just right.
Simply connect the standard 3.5mm stereo plug into your Raspberry Pi, Wave shield, etc. For power, plug the USB connector into anything that can provide USB power - This can be the Raspberry Pi at low volumes, but you're better off using a high output USB port from a USB hub or similar device. If you keep the volume about half-way (which is still really loud), the current draw is 200-400mA. At max volume, you can end up with up to 1 A peak draw. If a computer is not available, one of our 5V 1.5A wall adapters will work well and if you want to power from a battery pack, you can use a USB A to 2.1mm adapter if you don't want to cut the cord.
