The cord does what it's supposed to do, charge your tablet, but makes it very hard to use your tablet while charging. The card is too short to be plugged into the wall, and use the tablet while sitting in a chair right next to the outlet. The cord is only about 3 feet long, so you'll need to buy a dedicated extension cord to go with this charger, because wherever the charger goes, so should your extension cord. The usb end of the cord will not work with a car charger with a usb port, a computer, or most in the wall chargers with a usb port. Just plan on always charging your tablet with the oem plug it came with, and when your not using your tablet.
