Not just another spare cable with adapters for different phone jacks, we can easily use our car's only Android Auto port. The magnetic connection is strong, the adapters hold securely in the phone and ensure a solid connection with the magnetic cable (tested on Micro and C, no Apple devices here). The cords have a little blue light when they're plugged in (and the outlet is on), which is especially handy when we retrieve it from the center console storage area. Any. The write speed of my hard drive was the main limiting factor.
