Just a little something I threw together using an OKRT\6-W12, LED Voltmeter and some pc board screw terminal blocks. Left side in 12VDC in and right side is variable voltage out to whatever I decide to use as the PV w/ a pushbutton (bottom fed is a must!). Figure its better this way so I can take it apart and use it in something else. Have it plugged in to big heavy duty 1amp 120v in LED driver, puts out 5amps @ 12 volts up to 60 watts. Adjustable from ~3.2-6.1 volts. 
Thinking of finding a small desktop enclosure for the board, move the pot to somewhere accessible, hide all the wires and an outlet and put a master vaping on/off switch. Have it sitting on my future work bench I'm working on. My situation now is a tid bit cluster-uffed!
