Won't charge with non samsung charger after NK1 Update topic

I have several S4's here. One recently flashed with NK1 (still on NC5 bootloader, but NK1 based rom and kernel).

This phone will only charge when connected to the original samsung 2A charger that came with the phone. Phone refuses to charge off of any other charger.

I have another S4 that's mdk based running GPE (4.4.4) that will charge off of any charger.

Is this something new in NK1??? I don't recall having any such issues when on NC5.

Thoughts/comments?
