Hello,
I've bought Cigarette lighter charger to dual USB port. It works fine when I charge phone but my goal was to use USB port to connect another USB device ... in my case it was wireless adapter for CarPlay. It didn't work. I had to connect this wireless adapter direct to car USB port. Today I tried USB thumb drive with some audio files and again ... it worked from car port but didn't work from cigarette lighter converter.
Hence my question: should I find another car cigarette lighter charger/USB converter which will not only charge but also allow to use another USB devices?
Maybe it's not possible for any cigarette lighter to USB.
E.g. someone said that is one should work. What do you think ?
Thanks

 

I contacted manufacturer and they said me that Car chargers are designed to only charge other devices but not use as usb entry point for other functions
