Review on C2G Hospital Grade Power Cord: Perfect for Medical Carts and Mobile Devices - 16 AWG, Black, 2 Feet (0.60 Meters) by Bob Boan

This is a super heavy cable that appears to be very well made EXCEPT you can't connect a regular 3 prong power cable to it. I have to send it back. See photo, on the female end all 3 holes are the same size. This extension cord cannot be connected to a modern electrical device with a plus and minus pole. This is a major design flaw, especially for such a heavy cable.
