I put some resistors across it and it seems to be putting out the 5amps. I can't seem to adjust it much lower and the over current light is on. I don't have a watt meter, I could break the line and measure the current. Nothing is getting warm, I thought if I left it on something would, but nothing does. Yes, the voltage will adjust.
I will try a light bulb, I didn't trust it to try and power anything else.
