It consists of a weighted dock and a cable with mini and "A" USB ends. Then there's an AC plug with a female USB port.
The manual printed on toilet paper is several languages has a diagram of the dock connecting to an AC outlet and the dock itself. Next to that is a picture of a laptop computer with the legend "after you connect to a computer", below that are 3 inset drawings I can't make sense of.
So I plugged the USB into the dock and A/C power and everything works except the temp readout.
Still confused about if and when I'm supposed to plug into my computer.
