    Pros:
    It works great. It is one of the few that measures up to 10V (meaning that it works with Fast Charging currents - 9V). Using it, I have discovered that the Galaxy line does NOT fast charge while screen is on. Google it and you will find articles about this.
    Cons:
    Output 2 doesn't work with fast charging. 5V is top
