Seriously, this charger works very well and can deliver a full 65 watts. Power Brick, but it's a fraction of the size. I've attached an image showing the relative size difference. Another positive is that the adapter holds up very well after being plugged into a 12 volt outlet. I was kind of afraid that he would hang up and I would have to constantly correct him. Finally, the 12-volt power supply generates very little heat. I definitely recommend this charger.
