USB connection to car cuts in and out continually when charging

I have a Iphone 7s which has been fine connecting to my cars with USB. Recently, changed cars to a BMW and when connecting to USB phone charge cuts in and out continually, yet works everywhere else. No problem with cable??

Audi is a better iPhone charger than a BMW? Both are still very expensive chargers, though. But seriously, if the iPhone works with other USB chargers, and if the cable works with other devices, borrow a meter and check the USB power provided from the BMW. Check for applicable BMW technical service bulletins, and BMW firmware updates, too. Might want to check BMW forums, too.
