Do I need to buy a external power supply? I am just transferring data via USB and plugging in mice and keyboards.Does it have a port for a powercable?

Nothing else I could add that Bonnie K stated. It does seem to go in and out. The beeps are what is annoying. I have several things plugged in, even an external hard drive. No external power required.

No power supply needed, just a USB port to plug into on your system. The only issue I have with this product, it keeps disconnecting, it doesn't lock in very tight, so I always loose connection on it, which can get annoying at times. There is no port for a power cable at all.

Yes rather well, but need to keep in mind high powered USB devices will need external power. Adapter is meant more for storage or external wired keyboard/mouse

It came with a power supply. I do not remember if it came with a usb cable, it uses a standard usb cable.

Hello - sorry I can't remember if it comes with a usb cable. I already had extras and they tend to get mixed up. It does obviously come with an external power supply.

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

Yes, it certainly does. Without a power supply it would be totally useless as a USB 3.0 port could never supply enough juice to run seven devices. It also has an eSata cable that allows for even faster transfers if your computer has and eSata port.

No, there is a mouse joy-stick in the middle of the keyboard, but no external mouse, case, etc. It does include an external power supply, of course.

If I understand you right, yes. The hub is powered and will provide power to any thing plugged into it (optical mouse, keyboard, Thumb drive). The 2 "high" power ports are for fast charging something but does not fast charge if the hub is connected to a PC. They supply the usual USB voltage.

It does not have a power cable. It connects directly to your laptop and you are able to put on up to 4 flash drives and transfer information easily between them.

It includes a micro-usb cord that powers the device from your computer and transmits data from the built in USB hub. You can buy the extra power adapter, but it is not necessary.

It uses an external power supply. It only used the USB and thunderbolt connections for data transfer.

I don't remember any power plug included, but my computer had an extra power cable & plug available.I guess you could use a "Y" from the power to another device if you had to?

A power adapter is included, but you'll need to purchase a USB A to B cable (male to male) if you plan to connect it to a computer.

No, there's one USB plug that works both the mouse and keyboard. It clips to the back of the mouse when you're not using it.
