I had the same unit with my Mobius, and it worked perfectly for a couple years, then one side of the adapter began to work erratically so I stopped using it. I can't recall if my Mobius just shut off or went into standby but it did stop recording. I had another cam plugged into the second port and swapped them around getting the same results from the bad side.
I don't think the IQ-charging plays a part with this, but it can be an issue in powerbanks that have IQ which sometimes turn themselves off. Maybe Anker has changed the circuitry? I don't know. I was disappointed with Anker and still am, but I'd be willing to give their other products a chance given their good reputation.
