Only USB powered or external power ? If Usb powered, uses double connector or single for power?

It's USb only. It says to use double connectors, but I use it with only a single connector with my iMac; and it works fine. Using the double connector might make it a little faster, but this is fine for me.

I use a powered usb hub. So I can plug many things into the hub and it has it's own power pack. Then I don't overload the onboard power from the pc.

good question. mine cuts out with one usb drive but works fine with another. My toy won't work at all unless it is plugged in to power which defeats the portability aspect. :(

It uses two USB ports to power micro USB devices like portable external hard disks or external DVD burners, so you have separate USB for data and power

Both. You can use USB only, but if you need more power, you can use an ancillary A/C power cable. I have not needed to use the A/C cable with mine, but perhaps I have not stressed it as much as other people have.

Mine came with a power brick, for what it's worth. I believe that this hub corrupted my external usb 3.0 hdd, and pretty much killed it. Don't know this for a fact but I don't use it anymore.

No, you don't need power for this great enclosure. This enclosure is very good can take my thick HDD too while many others cannot.I just connected only 1 USB 2.0 to my laptop without external power. I have to use 2 USB on my other enclosures. But if your computer cannot give enough power you can use 2 USB cable or connect external power.

the drive requires the usb cable only! power is provided by your computer through that cable.

Only to power other USB devices. I regularly use it without power for hard network connection and USB drive.

Single USB connection. It does not draw power from the computer. It has a plug for external power. I don't like the external drives that draw their power from the computer.

One more thing, if I unplug the USB from the plug to use stand alone without extra power, but to use the device's charged power, it works fine also.

This unit is powered by the USB connector on your computer. No external power supply.

I have powered a small usb drive. I think the key is that you might have to use a drive that is only usb powered, but I don't know entirely for sure. You could always get the cable and try it.

The USB connector is only for controlling a PC via USB, not for powering. It's not very power-intensive and putting in a fresh set of batteries is easy.

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

There are one cable USB to an -Mini USB ( http://en.wikipedia.org/wiki/USB#MINI ) in the packet. Its Powered by the USB, no need for extra power.

Yes, one is for data and the other is for power. Sometimes a USB port won't supply enough power through one port. I have used an adapter that just had one USB. This one does require the use of both.
