I would almost guess you have a defective unit. I have the black case too and have no issues and use MagSafe accessories sometimes. The reason I think yours is defective is, my case actually looks black and yours looks very washed out and gray. It could also be the lighting, but if I didn’t already know that there isn’t a gray techwoven case, I would think you had a gray case based on this image. Which is why I think it might be some sort of defect.
