Is this a battery operated (true wireless) projector or does it have to be plugged in?

There is no battery in this device. It operates only when it is plugged in.

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.

It has a mini VGA port on the unit itself. The projector comes with the required cord to connect it to your computer.

I believe so. I was hoping it would be powered by the projector so we wouldn't need to plug it in separately. As that is the case, we haven't set it up yet and are using the wired connections already available to us. Eventually we want to go wireless so that folks with i-phone/pad/pod/etc can project to our screen.

The speakers can be run on batteries or plugged in, the transmitter must be plugged in to outlet

It's wireless. You can put it anywhere in the room that has a power outlet. Mine sits right next to the entertainment center on the floor.

no it is not. The device is horrible to set up even with office. I regretted buy it, should have bought a wireless projector in the first place. I suggest you do the same if finances permit.

Yes, it has to be plugged in. It does not come with a battery adapter. I had an outlet on my porch within reach, but most people probably need to use an extension cord.

Yes, it is not battery powered. It must be plugged into a wall outlet in order to work.

It is battery operated. My 5 year old enjoys it very much. I catch her in her room playing when I least expect it.

Almost nothing. This isn't an active device. It just a reflective screen meant to be projected onto by an actual projector. The only power used is for the little motor that raise or lowers the screen.

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

You can run the projector straight from wall power.The battery will charge when the projector is plugged into the wall and turned off. If the projector is turned on, the charging process is stopped and the projector runs entirely from the external power source. If the AC Adapter is then unplugged, the projector will switch to battery power.Optoma has sent me a replacement battery, and the life is now much closer to the advertised value(3 television episodes).

This model uses no batteries, its hardwired and gets its power through the main panel. Its not a wireless that is powered by batteries

The camera itself needs to be plugged in. But the monitor can run on battery power, mine has lasted around 10 hours before we needed to plug it in.

Hi. Wireless does not mean it is battery powered. Wireless refers to wifi video signal it transmits to a router. All wifi cameras needs to be plugged in for power.
