So does this need to be plugged in to get the power? Or is it like a power "bank? Can you carry it around with you while powering something?

Your car needs to be running, this needs to be plugged into the car, and whatever you need to be powered must be plugged into this.

Yes, it needs to be plugged in to your car's battery directly, or your car's cigarette lighter, while the car is running. It comes with cables for both. it does not store power, as it does not have its own battery.

It is powered through the USB port. Just plug into the USB port and it is ready to work.

I am not sure how it works? It looks like to me it has to be hooked into a power source somehow. I could use some help here as well.How do you hook it up?

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.

This unit comes with a micro USB cable. You have to plug it in to a USB power source. If the portable power supply has a USB connection, then you are good to go.

It needs to be plugged in. The cord is about a foot long so really not portable.

You plug it in. I works pretty well. It has better power than the battery operated kind.

yes, it does need to be plugged in. and there is an off and on switch too on the device to save on the electric bill

Portable does not mean battery-powered. It means it is light and small enough for you to bring it in and plug it anywhere.

I think they say not to use it plugged in, but the charging time is a short four hours and the charge lasts for many hours, so the power it uses without being plugged in is more than sufficient to tackle the job.

Mine also came with a power adapter. The adapter is pretty small in a small box so be careful not to lose it.

It needs to be plugged in to a usb socket to be powered. No on/off switch thus nothing is charged.

Steven it is USB powered but comes with a second USB cable to provide extra power if required. In my experience it seems to be needed. Regards John Docherty.

No. Just you plug it in till it charges. Then carry it like any other power bank. This thing is fantastic. I got one a couple months ago. Qi works great as do the two usb ports. You can't go wrong getting this.

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

It will not power up unless it's plugged in. After it's on you can unplug and use it fine, as it has enough charge for hours but don't let fall asleep:). It works fine except you can't turn it on unless it's plugged in.
