Woops you're right, the reviewer has used an USB cable to put his digital camera on the device. That can only work if one of the two devices supports USB host mode.

The reviewer never replied though, and doesn't state the exact model. In the link provided in the article you get to see the specifications and it doesn't mention USB host mode or USB OTG or copying directly from digital camera to device via USB! The item is also out of stock but several alternatives from same brand exist see http://www.usbgeek.com and search for DigiMate

I found this review too on DealExtreme its of an older version but it also clearly states this device supports USB 2 host mode / OTG:

Host Mode: Back up/copy files from many different kinds of USB devices (such as digital camera, card reader, mp3 player, flash disk etc.) to the HDD by one touch WITHOUT a PC or laptop/notebook.
Device Mode (MSD Mode): It is a reliable USB 2.0 2.5" HDD enclosure
No external power required when used as a HDD case only (Device Mode)

So in host mode it would need external power, as expected.

Also, there is the issue of data integrety. Although that is inherent to USB. The reviewer said this:

There is only one thing making me a bit nervous. Even so that so far everything worked well, files were properly stored on Digi-Mate and available for download to PC – one can never be 100% sure and/or verify that the files were transferred OK. So you are not completely at ease when you erase your memory card to make room for more videos. It would be nice having an LCD on this gizmo and being able to verify the files and their size. As for the data transfer speed, about 25 to 28 MB/s when connected to a PC and about 4.5 MB/s when downloading from camera (same as downloading to PC).
Oh, and the thing uses FAT32.
