Its not battery operated if that's what you are asking. You have to plug it in to use it.

It has to be plugged in for power source. I've tried using the on board memory and powerpoint player, but it is very slow and not worth it, so I utilize wireless or wired video connection from my computer playing through Powerpoint. This is very fast on and off and much lighter than the wireless LG projector(500lumen) that I purchased and returned because it wasn't nearly as functionally bright in a 40 person conference room, and travels like a brick. The ML 750 has a nice small and compact travel kit for everything.

Although the user manual does not say that it needs a power source, it came with a USB cable. I was not sure why, later I noticed that the device has a mini USB port on the side. I had it connect to my Cable box that has a USB port. The device did not work properly (it kept flickering) without using USB cable. It works perfectly now.

No, it is wired in directly, so a source of power must be present but a cord with plug could be added.

Its self powered. So just plug into it and youre good. It works solo or you can daisy link them together.

It does not provide power to any device. It is powered but does not provide power (other than through the USB ports)

This is powered by external electricity and needs to be plugged in. It includes a 110v adapter power supply cord.

You need to plug the phone into a wall phone jack - it is not wireless. However, it does not need power and does not have a power plug, only a phone input jack.

Every time you setup it needs to be powered. But once you have signal you can disconnect power to it

There is a DC IN port that will allow the user to charge the battery while actively powering and using the device just like cell phones. In fact I'm doing it right now before taking my speaker to work.

no, it is not powered. I used it in my home, which has aluminum siding on it, which affects cell phone, TV, radio.I put it in my dining room window and am able to at least sit in dining room and use my cell phone. Before I got theantenna, my phone was useless in the house, and the battery would be dead by end of day. Not it stays charged for2 - days depending how much I use it

Wired what? No, it does not connect via wire to you device or any for that matter. It comes with a charging wire and that's it. And obviously the box.

Yes. It needs to be on in order to charge any device could be in sleep mode if you want.
