What powers these speakers?

The speakers come with a 110V adapter that plugs into the wall. Any and all wireless or bluetooth speakers require a power source. There are some on the market that use batteries which would be great for the boat, camping etc. You can space the speakers about 4-5 feet apart and hide the sub-woofer within reach of the outlet. Additionally, unlike some sets, this entire system is wireless, not just the sub-woofer.

The sub plugs in directly. I assume there's a AC-DC transformer inside, but haven't opened it up yet.

Scott, you will need access to a wall outlet for these speakers. There is no way to power them without the wall plug.

No, these are not self-powered speakers. They need some sort of amplification.

These speakers are not powered and therefore will work anywhere. You must have a receiver or power amp in order to drive them...

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.

the speakers are powered and can take a powered line in. most dj's will have a powered mixer board for output. We have tied these speakers into a Peavey 1200 watt amp

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.

They are passive speakers, which means that they are unpowered and you need an external AMP/AV receiver to power them.

This is a set of UNPOWERED speakers. You will need an amplifier to power them and the amplifier you choose and what adapters you have will determine what kind of audio source you can hook up to.

There non powered regular speakers that need to be powered by a receiver. I have them and they sound great!

110v a/c - and they make a really great sound for such inexpensive small speakers. I was happily surprised.

Simply put, they are speakers that have built-in amplifiers. All you need is an ac outlet and a music source to get amplified music

I checked my speakers and there is no information relative to wattage. All it has on it is that they were made in China (Surprised?) They are very low wattage I am sure.

Great question! The speakers get their electrical power via your device's USB port! No wall socket adapter needed.

I have no idea since they have been plugged in since purchase. One has failed but the second one still works, after almost 3 years. I mainly listen to lectures and I do wonder if other speakers might be better for music?

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