This genuine Dell 24 Watt USB AC adapter ships with a Micro USB cable and the needed 3 prong power cord. Although this adapter originally shipped with the Venue Tablets, it is a great all around high powered USB power supply that will charge most tablets and phones.
Bought this for my old tablet (still working with no problems!) to have an adapter at work and one at home, to not have to pack one back and forth. Works as advertised. And it is the OEM for the tablet. Can't go wrong.
Charges my Dell Venue 11 Tablet and Keyboard.
