It wasn’t even heating anything.

Hooked it up to an automobile battery charger to be sure it had all the power it wanted and boy does it heat up metal. I need to heat small pieces of metal to make it easier to hammer and bend and this does the trick.

2 things you need to know to get this working:The voltage needs to be instant. I connected to this to my variable power supply but it wouldn’t go above 3v. I thought it was broken. I’m playing with it at one point just disconnected and reconnected the lead to my power supply without turning it off and it worked. Using my power supply’s on/off switch was preventing it from working. The led did not help debug this as it’s on regardless of it working.Another thing to note is that I could not get the screw terminals to work. I soldered directly to the board and that worked. But I don’t know for sure if that’s the case or it was just the voltage.So with that badly needed information that nobody provided is out of the way, let me tell you about this thing.It gets metal hot. But not crazy hot. I’m heating hall bearings. They’ve never gotten visibly hit, much less red hot. And getting hot-hot takes like 30 seconds. I guess that’s to be expected considering the size.

This is a good value module, worked out of the box for me. Immediately heats up any ferrous metal inserted into the coil. I am powering with 12V DC.
