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.
too short and thin wires soldered, high ripple output voltage, I replaced the 100mF capacitor for 220mF.
I use it to drive 16 14000mcd White 5mm LEDs SKU 1106 in parallel, real output current is about 330mA.
Good product for this money, I ordered 3 pc's and will by more for my diy projects.
