How are speakers powered? Only by USB cord connected to computer, or is that simply to charge up battery for use on the go with a phone?

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.

Powered only by the USB from speakers to computer. Which means you do not need AC power to use. I love mne.

The speaker comes with a charging cable (not a charging device). The cable is USB at one end and a 'pin' type connector at the other (speaker) end. The cable is NOT USB to micro USB. Lose the cable and you are screwed...

These are battery-powered speakers charged by a 5-V power supply. They will not blast you out of the park, but are great on the patio for background music connected to my phone via Bluetooth. If there is a wattage, it would be low, since they will work for about 8 hours on a charge.

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.

The speakers are powered up thru the USB connection to the PC. The plugs that go in back of each speaker have piece of molded plastic that acts like stand to support the speaker.

The cord is an usb cable. You can plug into any desktop computer or notebook with usb connection and the speaker will be charged.

Speakers must be plugged in to a normal household outlet (110v), or there is a compartment for 8 c-type batteries in each speaker. There is no provision for recharging. I have never used the battery feature, therefore I have no knowledge of performance or battery life.

No. The speaker gets its power from the USB port on your computer or player. (It also gets the sound from that port.)

the speakers charge through USB so you don't remove the batteries to charge the device. Hope this helps! =D

It includes a cable (regular USB cable to mini USB). One side goes to a computer and the other one goes to the speaker. If you have a standard wall USB regular charger, you may be able to charge it from the wall.

Any cell phone charger or USB port from a computer or charger works perfectly. The speaker takes a mini-usb plug.

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 speaker charges via a micro-USB port. You can plug it into a laptop or standard phone charger.

They have a power adapter. Unlike some bluetooth speakers, they do not have the option of using battery power.

it's recharged via usb port on a regular computer. it then has a mini-usb port to connect one half of the speaker to the other half. the little magnets that hold the two halves together are good, too, they're strong enough to hold the speaker together despite being dropped off the night table onto carpeting!(and the thing i said about it stopping working? forget it. after i talked bad about it, the darn thing decided to work again!)

Hey Ralph, Sarah's answer is close - it has a cord and is meant to be used plugged in but does not have an internal rechargable battery. So it's strictly a speaker for use in the house - a bit on the big side, too. If you want one that's portable you might look at the Philips Fidelio DS7700 which is smaller and has an internal chargeable battery and can be taken anywhere. Sound in both is really good (this one's a little better) if you're an ordinary listener like me (and not obsessed with the absolute perfect listening "experience"). Plus it charges your iPhone.

Yes, it's rechargeable, but it also has an DC 5v adapter that you can plug into a USB port. You can run off the DC power if you connect the speaker to your device with the auxiliary cord (plugs into the headphone jack of your device).
