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.

The keyboard on the unit I examined today was connected to and directly powered by the tablet through contacts on the keyboard folio behind where the tablet snaps in. It was not a bluetooth keyboard.

No. The keyboard does not have a battery. It uses the power from the tablet. You can plug a charger into it so the tablet charges.

Mine uses the same charger for the keyboard and the tablet. When the tablet and keyboard are plugged together, they will both be charged at the same time.

There is a mini usb port on the keyboard, but it is only used for charging the battery of the bluetooth keyboard.You can't, for example, plug a USB mouse into the keyboard and have it function.

There is a USB cable accompanying the case. Provide an initial charge to the keyboard by plugging into the keyboard and the USB into any Powered USB port. The packaging for the charging cable is provided with the item.

It does not work because the mini usb port on your tablet is slave port and does not supply power need for keyboard. You will need a bluetooth keyboard if you want to use a keyboard with that tablet.

You can charge the keyboard by plugging it to a USB port of your PC or to a transformer (charger) that takes USB. I used the charger that came with my ASUS tablet. The keyboard has a micro USB port similar to the ASUS tablet and comes with a USB to micro USB cable. It does not include a transformer.

The device has its own power cord. I do not think it is designed to draw power from USB but only to power the USBs in the device itself. Thus the power cord.

It includes a keyboard, with a usb plug. You will need an adapter to use this with a tablet.

It doesn't need a charging cable. The keyboard draws its power from the tablet.

I can't really answer that because I use Android. I haven't checked the battery from my tablet. I only check from my PC, and it seems good. I use Linux Mint, which required no drivers or downloading to have everything just work, after I manually linked the keyboard the first time. That part took a little command-line tweaking. Not so for my Android tablet (Nexus 7, so native Google latest version).

The box say to use the cable that comes with it. Also, I tried using that cable to charge my phone, and my phone wouldn't charge, probably because the cable that comes with it gives you less power output. Trying to charge the keyboard with your tablet cable (having more power output) may decrease the battery life on the keyboard. So the answer is no.

Both Mouse and keyboard get power from batteries. The USB dongle connects both keyboard and mouse to computer but does not provide power.

If your computer is equipped with Bluetooth then you don't need a USB port to use the keyboard as it is a wireless Bluetooth device. However to charge the keyboard you do need a powered USB port. Perhaps overnight you could use your available USB to charge the keyboard when needed.
