How are the speakers powered; usb or 120v ?

The AlienVibes are 120V - USB would not be powerful enough at just 5V. Note the transformer is inside the right speaker, so no power brick to plug in the AC outlet, just a regular plug.

No, the speakers are USB powered, so you just plug them into the USB port on your computer and you have power. They also plug into your headphone jack for the sound. So USB for power, headphone jack for sound. :-)

Just one USB connection. All USB-powered speakers I've seen work the same way: the two speakers are connected by one wire, and one speaker has a USB cable and a stereo miniplug cable to connect to a computer. Interestingly, the first time I used them, I didn't have to connect to any audio source. As soon as I plugged into power, I picked up a local radio station. No thanks. I'd rather spend twice the money for ten times the quality. Walk away from these. Any Logitech set will make you happier.

Input shown in the back of the subwoofer says 120 V ~ 60 Hz, not extended to 220 V. I have 220 V at home and will use a 110 V transformer allways for my speakers.

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

Hi CRSBRZ,No, the speakers work on a 110V. The shipping weight is about 39 pounds the box they are currently in measures 18x15x29.Thanks for your interest!

the speakers are powered by plugging the USB cable into your computer. I turn my computer off at night, so they turn off as well. If you leave your computer on 24/7, You would have to unplug them when not in use.

The speakers are powered via the USB connector, you don´t need an extra power source.

The speakers are powered via USB and the sound is transmitted from the headphone jack.

There is a converter power brick that converts 110V to 5.5V. The converter is connected to the amplifier via the USB cable. This is similar to how cell phones supply cables and converter.

There are two cables, USB for power and an audio (green) cable to plug into the speaker output. If you look closely at the picture you can see them.

They are passive speakers, so they are neither 120 or 220 compatible. You need a separate amp to run them.

USB ports are only 5 volts so if your speakers will not work at 5 volts then no. The speaker sounds like it only requires 3 watts to operate (Watts=voltage x current). I would suggest getting a 6 V. battery from Bixpower with the correct cable.

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.

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

There is an earphone jack, and usb for power. Though I didn't have a high-powered speaker system to plug it into, my computer speaker set sounded bad.

I have the same question and there isn't a clear answer with rationale. Can anyone chime in on this? My speakers are not USB powered. They have a dedicated power supply.
