There is no USB power input on this unit. Power is supplied and the internal battery charged by the supplies power supply/plug. If your USB Battery had the appropriate plug adapter, I could see that working though. Hope this helps.

It is powered by AC only (no battery to charge via USB). It does allow the ability to plug in a USB thumb drive and share that on the network though

No it is plugged into USB port but for me it does give any sound though I raised the volume of the speakers

It is not USB powered, it comes with an AC adapter... however, a word of caution; when I purchased this it came with a "travel" AC adapter meant for outlets in Europe and will not work with US outlets. I had to research to find the correct AC adapter to get it to work and they ended up giving me a refund. It does work though, if you find to correct AC adapter which might be too much trouble for most people looking for a simple solution.

No. I'm pretty sure it says somewhere in the product description that the device can't be powered by a USB port.

Powered by USB, whether off laptop, desktop, or direct plug with a USB port. I love it!

Just USB powered but I haven't had any issues with it. Albeit, I only use it on rare occasions for work

Yes, the USB plugs in, then attaches to the power adapter that goes into your wall. If that's what your question means.

I am.not sure. We use it as an interface for wireless headphones. The power is supplied by the USB port.

No. Powered off USB plug. Great scanner, If doing hi-res work make sure to run the calibration procedure before you start- worth the extra minute!

No. This device does not need external power. Direct plug and play ( like a thumb drive)

USB output? Doubt it! It doesn't even have an electrical cord ...battery operated

No it is powered through the TRS cable. You can order a different length cable online - just make sure it is a TRS male to TRS male cable.

Yes it is USB powered. It charges up pretty fast and the charge lasts several days with a lot of use. I have yet to have a keyboard need charging. I just recharge mine when I recharge my iPad. It comes with the USB charger.

No, only a USB cable and a USB to DC adapter (in case you want to give it extra power directly from the laptop).
