They require DC voltage. They are rated for 12V. They come pre-wired for connection to an AC/DC converter. I wired them to a 9V battery and they work fine.

Hello John. The speakers have a standard, stereo, micro-plug. Yes they need to be plugged into household current and are equipped with the necessary power converter.

Yes, they need power to work, but they are dc voltage so you could rig up a power supply on the board

Require power source of 12v DC. Could run on a 12v rechargeable battery pack not sure how long depends on battery pack.

They don't require a battery in general. Just insure that the Head unit you are using to push them puts out a suitable amount of power. 50 watt RMS would be perfect for these.

Unfortunately they DO need to be plugged in all the time in order to be used. For outdoor use you will need a portable power source. I recommend Paul C Buff's Vagabond Mini Lithium portable power. It's light weight, easy to carry and it costs less than $250.

No power supply. They can be powered by POE or you can buy a power supply on Amazon.

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

Yes, the cameras need power. The battery connection is merely for testing purposes and will only provide power up to 15 minutes.

These lights do not use batteries. They require either a wall outlet or a DC power source.

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