  • Great for anything USB powered

    Involvement:Expert (understands the inner workings) - Ownership:1 day to 1 week

    Pros:

    Compact and simple.
    Draws practically no current by itself (when not under load).
    3A output?!
    Pretty good price.
    Virtually no heat dissipation, so no heat sink needed.

    Cons:

    This module was obviously designed as an SMD (Surface Mounted Device) to be soldered directly to a PCB (Printed Circuit Board), so it does not have any pins or connectors. Soldering wires directly to it is somewhat tricky, but not impossible. I stuck the whole thing with the wires soldered to it into a heat shrink tube to protect it.

    OtherThoughts:

    It should be internally overload, short circuit and overheat protected, but I can't confirm that.
    I got one to rig up a 4 port USB power supply for my car in place of a bulky POS that I currently have. Another one will be used for a powered USB hub, yet another for my motorcycle GPS/cell phone power supply.

    Bottomline:

    With so many devices that use 5V DC (practically anything that powers through USB ports, plus a lot more) this thing has many uses!
