Is this Apple charger cable genuine?
I'm going to go out on a limb here and say that imho, anything claiming to be designed in "Califomia" is not a genuine Apple product :3

Apple's official article -- Identify counterfeit or uncertified Lightning connector accessories -- may help you confirm my suspicions.

For those not liking hidden links the full address of the Apple article above is https://support.apple.com/ht204566
