USB interfaces - charging current
Sorry if this has been brought up before. Traveling during the holidays, and the search function in the mobile app and me are not compatible...
Anybody measured the charging current of Apple devices when connected to the USB interface in the center console?

The 2.4A USB adaptors are great suggestion!
Here's another example: I use these in my car - one in front and one for the backseats - these are flush fit so looks a bit more 'integrated' https://www.amazon.com/AUKEY-Charger...sb+car+charger |

I don't expect more than 500mA. But was hoping someone actually measured. I've got some old cig lighter plugs with enough juice, but are considering the ones linked to Amazon here. Thanks!

If you want fast charging for Apple devices, you get a better USB adapter. I'm using the same one that MechX3M40i is using, and it's pretty good. I only now need to find the equivalent for USB C. |

But yes I've heard contradictions here, and just wanted to measure.. Since iOS 11.2 it actually supports faster wireless charging, but yes the BMW pad does not support more than 5W in good conditions... https://www.tomsguide.com/us/iphone-...view-5042.html

Crappy BMW adapter (5W/1A only): Good Aukey adapter (both ports support 12W/2.4A): BMW car USB port (5W/1A only, not surprising since the port also does data transfer): |

One thing I can add here is that wired charging speed is also greatly influenced by the quality of the cable. I always buy generic replacement cables from Amazon for the cheap prices. Most of them were/are good enough, but occasionally received some that were less than desirable (even within a batch of good cables). For those whom have critical need for 'speed' (pun intended) than you might want to consider Apple brand.
