Does it have to be plugged in or is it rechargable? My office requires IT approve computer USB devices and facilities approve AC powered stuff.

its a usb but if you have a phone charger that you plug in that will work to

Your IT dept. likely requires you to check with them for anything accessing data via USB, not something like this which only uses the USB as a power source. If the IT dept. has to have you check for something like this, then you need someone new in the IT dept. that better understands what IT is supposed to be doing.

It comes with a USB cable. You can run it via computer or with an adapter via outlet.Amazing device btw. I own seeveral.

It is powered by the USB connection and doesn't require an additional power supply. It is not wireless and must be connected with the USB cable.

It has an internal battery and you recharge via USB either plugged into computer or a wall plug. You can also use it while plugged in.

It needs to be charged. I bought a car charger for it and keep it plugged in all the time!

That other answer is not entirely correct. A powered hub can operate on USB power only. It does not NEED to be plugged into AC. It will work the same as an un-powered hub, which will limit you to a total of 500mA of current draw from all ports combined. However, if you use the AC adapter then you will have up to 500mA per-port (2A total).So if you are only going to connect low powered devices, or self powered devices, then the AC adapter can be considered optional. If you need to connect devices that draw more power (portable hard drives, USB powered scanners, burners, etc.) then you would need to use the AC adapter to supply the additional power.

It is rechargeable. It comes with a USB cable to connect to your computer for updates; it also recharges while connected.

The adapter I have is AC powered and not battery operated. I don't understand the question: "without AC adapter..." and "rather than battery operated." If it is not powered by AC or a battery, how is it supposed to be powered. This unit plugs into an earphone receptacle on the computer. These ports don't supply power like a USB port does. I don't think my answer helps much.

It is powered off the USB bus. I use an adapter plugged into 110 volts to insure constant adequate power (because some USBs have more power than others).

Plugs into any 110/120 v outlet. Needs to be charged up at least once a month. Can be left plugged in all the time without overcharging.

Mine actually has an AC adapter so we plug it in to use it. I heard the rechargeable ones didn't work too well.

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

By default it needs to be plugged in. I think there are wireless dongles for it also.

it's recharged via usb port on a regular computer. it then has a mini-usb port to connect one half of the speaker to the other half. the little magnets that hold the two halves together are good, too, they're strong enough to hold the speaker together despite being dropped off the night table onto carpeting!(and the thing i said about it stopping working? forget it. after i talked bad about it, the darn thing decided to work again!)

It is designed to be plugged in. It has a cord not visible in the picture. (It is a great little personal lamp.)

There's an AC adapter to charge it....I haven't tried keeping it plugged and using it - but once charged it will keep for quite a long time I've noticed!
