Doesn't even come close to the stated output

I tested this unit with an input voltage between 9V and 14.5V. The output voltage was unacceptably low for any USB powered device, except maybe a very slow. load. With a power consumption of 4.5 watts, the voltage drop for my USB device was enough to issue low-voltage warnings, regardless of the input voltage. It just can't deliver the advertised performance. I would look elsewhere. As for the pros, it looks well built, fully loaded and the wires are well connected.

Pros

Impressive

Cons

No automatic control
