3-foot black AC power cord comes out the lower back of the right side speaker and another thinner cord plugs into the headphone port on your computer,sending the sound and music from your computer through your new Logitech speakers.

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.

The power source comes from the computer once you conect the jacks from the hub. Once they are conected then you can plug your headphones and speakers into the hub. Your speakers will no doubt require a dedicated power source be it batterys, USB or other.

They are powered they plug into 110V. Awsom sound for the size. I like them better than my other tv's 5.1 speakers.

These are self powered speakers. The amp is built into the speaker and therefore must be plugged into an electrical outlet as well as to the computer. Had them a couple of months now and continue to be very pleased.

These speakers are not active and do not require electrical power. They have only one speaker wire input.

These speakers must be powered by the ac cord, they are not battery powered, so there is no charging involved.

no, these are not powered speakers and the volume would be controlled with a powered amp (stereo receiver). they have a very nice white grill. you can't see the speaker with the grill.

These are not powered speakers, they need to be connected to a receiver or amplifier. If you wanted to use these with a computer you would first need to connect the pc's audio output to an amplifier.

These are not powered speakers. You need an amplifier. So these are definitely not meant to be hooked up to a computer.

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.

These are not powered speakers. They are standard speakers with input for speaker wires coming from the stereo amp/ tuner/receiver at whatever voltage that runs on. I hope that helps.

that is correct - USB cable & AC power source (adapter is supplied) for the speakers as they have a pretty powerful amp in them!

These speakers are not powered speakers. They connect using speaker wire to a receiver or amplifier. I have a pair of these connected to an inexpensive tripath amp and the amp takes the aux connector from a laptop or smartphone.

The previous two answers are correct. These are not amplified or powered and require an amplifier. The volume is controlled on the amplified device.

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.

They are a passive speaker, not powered, They need a receiver or an amplifier to out put sound.. hope that helps.
