Micro-controller and a 12v power supply

    Recently I was able to get my micro controller (an ESP32) to control a vape through a
    IRLB3034 mosfet. The system has a 12v 1A power supply and I was unable to get that to drive the coil. What I did was use a 3.7v battery and run that through the mosfet to the coil. Sure it works, but it was not ideal. Is it possible to drive a coil using current from the 12v 1A power supply?
