A few final thoughts on my counterfeit MagSafe charger situation:
I reached out to Woot, who were apologetic, but since I've had it >90 days, they could only offer me $10 off my next purchase. Not the best, but not the worst solution.
Literally the only visible difference between real/fake is the etching on the puck-end where the wire attaches. The fake doesn't have the symbols and "R-NZ" etching. Everything else including serial number on the cord, material quality and packaging is spot-on (well I no longer have the counterfeit packaging, but it would fool anyone without a genuine one side-by-side).
And finally, I bought a new one to replace my counterfeit. Plugging it into my MacBook Pro for about 2 minutes did force-update the new charger's firmware from 174 to 255.
Is your Apple MagSafe charger genuine? Check if you're using an original accessory, if iPhone 12 wireless charging doesn't work as it should!
