Hello, I have this power supply for breadboards. http://wiki.sunfounder.cc/index.php?title=How_to_use_YwRobot_Power_Supply_Properly More: https://protosupplies.com/product/ywrobot-breadboard-power-supply/
I plugged in a 12v wall adapter as instructed. I plugged in a battery charger into the USB port (no battery connected thank god) and probed the output of the charger, which fluctuated oddly between 3.7v and 5v. Then I noticed the adapters light flickered, went out, and the adapter started smoking and the plastic started melting. I immediatly turned the psu off and unplugged it.
The battery charger is toast. The power supply seems unharmed.
I probed the output of the USB port. It was over 15V! The input voltage to this power supply is only 12v.
I probed the output set to 5v. It was at 15v. I set the output to 3.3v, and it went to 3.3v. I turned the output off, and it went to 0v.
Am I using this wrong?
