Works perfectly with my Gateway C-140 series tablet PC using one of the included tips. Very light and compact! I also like that it has a USB power port and that it is Energy Star certified. My only complaint (and hence 4/5 instead of 5/5) is that the AC wall outlet cable is actually as short as shown in the product images! (I had erroneously assumed that the image did not represent the actual length and was only meant to show the ends of the cable.) It is only 6 inches long. Which means that when plugged directly into the wall outlet the adapter sort of hangs there without anywhere to properly rest. Not a problem if you (a) plug into a surge protector or the like, or (b) do like I did and just replace the cable with a longer one I had lying around (or can buy for ~$2 online). The cable on the other side of the adapter that connects to your computer is ~6 ft.
