How do the speakers get electric power?

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

Plugs into USB on my laptop and mic connection; power comes from the laptop.

This speaker(s) come with two plugs. One is 3.5mm stereo plug for sound and the other is a USB plug for power. Plug USB plug into your computer's any available USB port. This is used for power only.

The speakers get POWER from USB port, get SOUND from headphone jack separately. Ad misrepresented it, saying BOTH sound and power came from USB

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.

The 1C speakers are passive so they need power to operate. Customer needs to purchase an amplifier.Behringer NU1000DSP iNuke Power Amplifier

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

Ye you need an amp, they are not powered speakers. They are passive speakers as indicated by the "P" in "B2030P" which means you need an amp to power them.

They will power on as soon as the ports get power. I have them plugged into an active port, so the speakers are on all the time.

1) The rear speakers need to be wired. They are not wireless.2). The main power input to the system is 115V / 60 Hz (standard North American power). The power to the rear speakers is 115 Watts. They do a very good job in a large living room.

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.

The speakers need electric power, but use 2.4GHz (same as bluetooth or WiFi) to communicate with the sending unit. The power cords are a standard 3 ft. These work fine if you are not relying on something like an iPhone that is reading off the WiFi or another bluetooth device, as it interferes with other devices on that frequency.

None of the speakers are battery powered. There is a receiver box for the rear speakers which is wall powered.

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

I just ran the power wire to the power on the switch then to the battery. It's easy. The system sounds great to. The speakers are really big. They were bigger than I expected when they showed up but they sounded great.

they come with power adapters for both the transmitter and the speakers. so you can run any of the items off of batteries or plugged in. if by "regular speakers" you mean plugged into your receiver with speaker wires, than no, you can't do that.

They are powered by the subwoofer, the big wooden cube you have to plug into a wall outlet. Have some space available for the subwoofer, the control wire and speaker cables from the satellite speakers are long so they can reach pretty far.

They are electric, so you need an outlet, or an external power source such as a generator.
