Review: Great Replacement Power Supply - The power supply for our small greenhouse stopped working. I read the volts and amps off of the old power supply and searched desertcart for a power supply with the same volts and amps and I found this one. The tip fit in the greenhouse power port and has been working for a couple months now. I did not have a way to measure the output end of the plug. I just assumed that there was a standard size for 12 volts and 3 amps and my assumption appeared to be correct. Makes sense so we don't plug the wrong power into the wrong device.
Review: No Issues - Works great!!
