Me neither, don't know what all circuits power on, I unplugged it, till I get my cord and blocking diode strait.

With booster powering the 12v outlet, the radio worked, windows worked, I have my passenger airbag off, when ignition off the airbag light went off, buzzer was off, blower was off.

If there is anything you want me to check if powers on or off through 12v outlet without the key let me know.
