Worked fine in our production of baby.

These work great on my galaxy 20 phone and earphones. Positioning of the phone using the cd-slot mag mount for the phone puts it in front of the head unit for easy control. I use it to plug in and charge my ipad pro via a iphone / headphone charger.

The plug fits my samsaug but doesn't fit any of my usb plug. The drive specs according to samsung are 500mb per sec. Fast charging is a joke, i'm lucky if i can get them to charge at all without disconnecting.

Only way i take down this review is if i get a refund. Horrible product. Do not recommend.
