Does it still work somehow when it is plugged only to the computer without being plugged to electricity?

I just tried mine without the power plugged in, and it worked OK with the track ball that is plugged into it. However, I suspect that any device that requires power from the USB bus (like an self-powered hard drive) would NOT work unless the hub itself is powered.

Not as far as I can tell... Now that you asked, I turned it off and the peripherals that where connected through it shirked and went blank. Ciao

Mine did not. I happened to have recently bought a power pack to charge my phone. I use it on the light so I don't have to use the computer as my energy source.

From what I can see, the answer is 'NO'. When wired, it gets charged, AND I just tested this by removing the receiver from my computer and it did not work. Then plugged the receiver in and it worked while being connected.

No plugged it in my pc. The whole reason I bought it, so I wouldn't have to use outlet. So I can't really answer that question with a yes....

yes, the battery is required when connected to the computer. Just tested it to make sure.

It has to be plugged in to a USB port. It works when the computer is in sleep mode but not when the system is off. Good product, no regrets.

As far as I know, it only works while plugged in. At least that's how mine works.

No. After use I unplug from electricity. I use this only once a moth to backup my computers.

No, you can't use the device while it is connected to your computer's USB. You can, however, use the device while it is plugged in to an AC or car power adapter. So just get an AC adapter to charge instead of using you machine and problem solved.

According to my wife the answer is no, it must be plugged in. She loves it though.

If you had it plugged into a computer it probably used the power from that. It didn't work for me without the adapter being plugged in. If you don't need it, just put it aside just in case you do at some point.

Yes, you use the USB cable for setup on your computer, after that it's just used for power

I have mine plugged into a PSU. This is likely the only way to receive power.

If the question is does the speaker still work while unplugged it does if it's charged. It is not an electric generator however.

No it's strictly plug in. If that's not a showstopper, then I would recommend it. I use it frequently!

The cords it came with are the only ones that will power it. I tried hooking mine to my computer and lap top and it didn't work.
