Pretty powerful for USB

Bought something to keep my internet router cool; wanted it to be able to be powered off of the actual USB port on the router itself. This thing did the trick; the 1.0A that the USB port provides was enough to power this little baby at the max setting. Speaking about settings; this thing puts out some good air. I'm really impressed! The top setting is substantially better than most AC-outlet fans and i'm not exaggerating about that. The one con I found was that it's starting to rattle a bit after only a week of use. Granted, I have it running constantly. And it's not very loud rattles, just abnormal and slightly noticeable. This won't be a problem though as long as it doesn't get any louder.
