Narrative:

Upon entering the cleared safety zone into gate in ZZZ; I inadvertently shut down #1 engine when I shut down #2. We verified brake pressure and brakes and rolled to a stop by the marshaller's guidance. I used 2 fingers on the start lever when I usually use one. I intend to be more vigilant in the future and only use 1 finger on the start lever and make sure both aren't coming down when I'm selecting one. We then completed the parking checklist to end an otherwise normal flight. Supplemental information from acn 827144: both engines shut down as we joined the j-line and we lost electrical power to the airplane. After we came to a stop; the ground crew had the ground power plugged in within a matter of seconds so we returned power to the airplane with ground power before the APU was done spooling up.
