Product review (5 stars): It's a 50Amp power cable
It's sturdy/high quality, there isn't much else to say about it.  It does what you would expect from your typical appliance cord, it's pretty hefty and has a pretty solid outer jacket (a pain to trim back, if you need to).  I installed this in my new EV Car "Charger" (EVSE-- I assembled it myself, the JuiceBox Premium) so I had to modify the outer jacket some to be able to get the leads to reach where I needed them.
