looking for battery for my HD

[cordvision]

I'm looking for a battery pack that I can attach over usb to my mobile harddrive to use it with my hvx to offload p2 cards. Do you think this would work? any suggestions on what to buy?
I found this one --->

Your link doesn't work, it is tied to a specific website visite / session.

If your drive is a USB OTG (On The Go) hard drive, it should have its own power source. If it is a Firewire drive, you have to find a different way of powering the drive, you can't use both the Firewire and USB interfaces at the same time, even if the USB interface is only used to supply power.
