    great product

    posted by Tribukhouski on 09/21/2012 Certified Owner

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

    Pros:
    Small size, cheap price,accurate soldered, good known MC34063 chip, driver really can produce 3w output power, has ss14 diodes bridge - not sensitive to the polar-ity of the input DC voltage and can work on AC too.
    Cons:
    too short and thin wires soldered, high ripple output voltage, I replaced the 100mF capacitor for 220mF.
