This is a high efficiency switching mode "step up" 12v regulator with high current output. The module has a heat sink mounted, so overheating is minimal. Output is regulated to DC12V with low noise. It is perfect fit for all class vehicles, boats, or bikes with 6V electric system, but needs 12V for modem electronics equipment. Of course it works great for the solar system by stabilizing its output. No pigtail required.
