Last night I went out to take a picture of the full moon with my telescope and brought the az gti mount, but when I plugged in my mount to a power bank ( i checked th output it was 120v) using a 12v 1A chord, it started malfunctioning and when I opened the synscan app and tried to connect it, it wouldn't move at all and the screen that showed how much angular distance was remaining went extremely fast even though it wasn't moving. after that happened I tried just unplugging it and using the batteries but the same thing happened. I hope all that happened was I blue a fuse and no internal circuitry got damaged.
