do these speakers get their power from a USB cable plugged into the computer or an electric outlet?

Electrical outlet. There is a power cord attached to them and it plugs in to an outlet.

They are powered by an AC adapter via electric outlet. USB just doesn't have the power to push out good sound in most cases.

Speaker dimensions are 2-1/2 inches width, 2-3/4 inches depth, and 5-1/2 inches height. You don't have to plug them in to an electric outlet; they operate by just plugging the USB cord of the speakers into the USB port of you computer. Very simple and efficient. Hope this helps.

There is NO voltage going to these speakers. They are not powered and they need an amplifier to operate.

Hello John. The speakers have a standard, stereo, micro-plug. Yes they need to be plugged into household current and are equipped with the necessary power converter.

They are powered solely by the USB port, no battery. They are GREAT speakers. I use them in seminars and, unless I need to reach the back of a large hotel ballroom, they do the job for most groups of 50-100 people. And they fit right in a pocket of my laptop case.

The speakers are powered by 110v house current, or it also has provision for batteries (that I have never used). They work well on house current.

These speakers are passive, and not powered speakers. You need an amplifier as well as your computer to get sound out of the speakers. If you want to get a pair of powered speakers, then you can just have the computer send a signal to the speakers and they will work. But, you must be able to control the volume level from your computer. Hope this helps.

The speakers are powered. All you need is an audio source. Computer, TV, MP3 player, etc.

The speakers get power from the USB and the sound from the Jack input. Hope this helps.

No- to my knowledge it does not plug into the computer. My sandisk does plug into charge -but i dont think that is for power to the speakers. it has a place for a dc-6v - but you must buy the cord - there are no usb ports on the speaker system. We just do batteries and it works for portability.

No, these speakers get power from a USB port and source input from a hard wired auxiliary cable. There are no other inputs or outputs

Carrie, the speakers are powered from 110v house currant. There is an on/off switch and a tone control on the right channel speaker. You have to turn them on and off seperate from your computer unless you have a power outlet for 110v on your computer.

Standard usb power. (Any generic wall outlet block will do or powered usb port on computer/electronic device) The speaker charges via mini usb.

There is no direct AC wattage draw. The speakers draw power through a usb cable from your computer. i would imagine the power used is quite low.

The plug is not USB. It is 'single pin' to the headphone/speaker port on your computer. Do note, that the speakers do require to be plugged into a wall outlet for power.

No. these don't. They work only with the USB of your computer. They are just not loud enough. The others which are also Logitech, do need to be plugged in but they give a good sound output. I hope this helped.
