1500x charging on and off

I just had a 12v plug installed in the bed of my truck. Just went to charge my 1500x with it and it take a charge for a few seconds then turns off, this continues to happen. Watts in jumps up then goes to zero and jumps right back up and back to zero

I plugged into the factory 12v lighter in the truck and it charges just fine. Wondering if I made a mistake having the 12v installed in the bed. Anyone have an idea as to what’s going on here?

Thanks in advance for any advise.
