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