I thought I spotted the fake on the left because of the small, white, rectangular piece right below the red LED. On the left, the thing is looking much darker.

Because there aren't high res images, ironically, it's a bit hard to tell. But the best way to avoid a fake is to actually buy it from the official shops. That's not to say it too is 100% guaranteed as someone on the inside could have easily swapped the supply for a cheaper source, but it's still your best option.
