I recently bought a Konnwei based on the recommendation of the LeafSpy app, and I'm trying to determine if it is defective. I don't see a resistor as indicated in the original image. Here is a picture of my adapter.
When I measure the resistance it appears to be 27kohm which seems like it would be more than 120ohm, but I'm not confident enough in my EE skills to be sure.
I'm I correct in thinking it is safe to use?
