This unit is perfect for automotive application if you can tweak a little bit. It has rectifier which makes the unit usable for AC. And in addition it also makes it non-polarized for input. That is... you don't have to find out which is positive and which is negative for the input. (you still need to consider that for output, though). The problem is that it generates huge amount of radio interferrence, so that the FM radio is no longer audible. What you have to do is to remove the diode bridge rectifier and connect + to + and - to -. In my unit the rectifier had "MBS6" label on top and + and - indicator. I simply cut the legs and soldered small piece of metal legs from spare resistors. Then the radio interference disappeared completely. You now have to make sure the polarity of input, though. It is running perfectly and driving two red CREE LED in serial without any problem.
None unless you mind soldering.
Great price and great product.
