There are actually 2 generations of devices, the 1st one has a fixed length USB-A cable whereas the 2nd generation has a USB-C input and you can use your own USB-A to USB-C cable (a short one is included ). I find the gen2 devices more practical, smaller and estetically more polished
you refer to the Carlink-Adapter, don’t you?
i received the CPlay2Air adapter last week with a fixed cable.
