This has it's own power supply. It's a very nice drive and has not given me one ounce of trouble...

Yes, it has a power supply. It actually is powered by 12v but has the typical power converter built into the wall plug assembly.

I have the fantom 4GB and it came with a power plug that is attached to the back, I would think the 2gb would also come with one.

No, to power it, it came with a USB cord that can connect into a USB port on a computer or USB wall adapter.

It is plug and play. You don't need a power supply. Plug it in. And it should set up.

No, it does not come with a power supply. You will need to buy memory, a hard drive or SDD for storage, a computer case, and a power supply.

It does not come with a power supply. You have to buy that separate for another $20.

Yes, it includes the power supply, but it is not necessary. I have it plugged in to my desktop computer with just the USB connection and it powers it just fine. I cannot speak to the performance of the product on laptops or other portable devices.(edited for a typo)

No external power supply is needed. It is "plug & play". It gets power from the computer's ExpressCard/34 slot.

It is not USB powered, you plug it into a regular power outlet. It does come with a carrying case for easy transport, though. It's larger and heavier than most "portable" drives. Good drive.
