Do the speakers work without a power source? Are they portable?

They need to have an AC plug in to work, but that is your only limitation. Very portable as long has you have an outlet

They require 120VAC power, i.e., need to be plugged in. They are portable, but need a power source.

No... Speakers must have a powersource. They are portable, if you have an AC power source. Great pair of speakers

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.

Yes they need a lot of power to work .. I run the pair off a 100 watt receiver and they sound ok .. You get what you pay for

They are wireless - you do not need a cable to connect them to a computer or your music-playing devices. However, they need a power cord and there is also a cable connecting the two speakers.

These speakers are not self powered. You will need an amp of some kind to power them. They are good speakers for the price. I like mine.

The speakers are 110V and need to be plugged into an outlet. The speakers are also connected to each other by a 6' cable which is included.

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. :-)

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

yes, the speakers are powered by a separate cord from the amplifier box to the power source. They are used by my wife in her sewig room and she likes them very much.

No separate power cord necessary for these speakers. They are powered through the audio cables I have two and use them with a sound board. I have run my laptop through that board for music as well as doing outdoor movie night. They sound great.

Hello,I see you had a question, to answer your concern: these speakers donot require batteries, nor do you have to plug into a electrical outlet. A USB plugin and sound input is all that's required.

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 use mine connected to a desktop computer sound card. These are powered speakers any they will work on anything that has a line output If I remember correctly the speakers were about 20 watts which may cover a small back yard.
