The description of this product should be updated to specify that the tip is center positive. Getting the polarity wrong can cause lots of problems.
EDIT: False alarm, the voltage output is solid, and my multimeter was deceiving me.
Not gonna mention the extra USB charging port?
(It's always 5V, I hope?)
Ok, I just tested with a mutimeter. I adjusted the voltage as well to 12V on the cable just as a quick test and the USB port is about 5V as expected. My co-worker just updated the product description and features tab. =)
Nice catch. I haven't tested this power supply yet but the sticker indicates that the extra USB port outputs 5V/2.4A.
