M6 Pro MR6550 Faulty Power Adapter

I purchased a used M6 Pro that did not come with the power adapter.  I saw the same error when I tried to run with the battery removed.  I tried several different power adapters and still received the same warning message.  In another forum someone said they solved it by using a Quick Charge 2.0 power supply.  I tried a Quick Charge 3.0 power adapter and the problem went away.

I am speculating that Netgear may be monitoring the Quick Charge hand shaking protocol and if it is not detected  (the adapters I tried were not labeled Quick Charge compliant), it gives the warning message.  I have now tried two different QC 3.0 power adapters that work fine.

I got a M6 Pro Unlocked MR6550 for a US colleague, and when using the original power brick and cable, the nighthawk doesn’t boot and says “use the supplied power adapter when operating without battery”. Which is funny because it is the original power adapter and cable.

I’m getting a new power adapter from Netgear, but I’m curious:

Could someone do me a slot and send a pic of their M6 Pro US power adapter. Specifically the text part that has the input output info.

Has anyone experienced this?

Sent PM to you. Please check. I would like to get your set of USB cable and PA back to check.

Thanks
