Got my D4 from Aliexpress from a seller who stated that it’s “100% original”, with more than 1000 orders and very good marks for that product, I thought it actually is authentic.
Turns out you can fool the vast majority of buyers, because now looking at the negative feedback , only 3 buyers complained it was a fake.
It is a good overall fake, even the cable is branded Nitecore as are the capacitors.
Scratching the verification code only to find out it was used before (and now i see the exact same number was used for another post on this thread) googling the number also leads to other buyers with the same number.
Here are some photos of my unit:

I would rather have a coke in the evening…

Nowhere on the PCB does it say Nitecore or Sysmax

Nitecore printed on all electrolytic capacitors

Crooked soldering on the push button

The AC socket looks like the authentic one

And the verification
