Summary: It worked wonderfully the first few weeks I had it until one day it decided to sound comparable to a jet. ( I could hear it across the house) I had to unplug and replug it every time it decided to act up, And that was every time it got bumped in the slightest.
Pros: worked well for a while , unobtrusive , cord storage
Cons: worked terribly the rest of the time , my 17.5 inch laptop likes to slide off , when i bumb the cord i get a "new device found"
Must use external power supply to get max from pad
23 January 2012
Summary: You must use external power supply to get the maximum chilling and USB capabilities from chill pad. The power supply is listed under: Shop; Accessories: Optional Accessories; AC Wall Adapter, on their web site but they do not sell item.
Summary: I have always stayed away from Targus products but finally succumbed to this cooling hub. It is impossible to purchase an AC Adapter for it because Targus doesn't make an effort to provide one themselves or from any other manufacturer. No indication for correct voltage anywhere.
Summary: Okay, I had purchased my original Chill Mat at one of those big bargain stores, didn't realize what I had until I'd used it a couple of years and into the ground. Threw the first one away knowing it had a port for a wall unit to run the auxiliary USB hubs.
Pros: dual fans , 4 usb ports , potential for wall power adapter
Cons: requires some thought to set up. , usb port drivers need to be installed , need to purchase the power adapter & guess volts
