Some are gonna use LukiLink with Android phones, and some are using iPhones, we don't provide cables, since you can use the cable that already comes with your phone (charging cable). The same goes for the HDMI cable. Different cameras come with different versions of HDMI. So there is no "one size fits all" solution. So it's not only easier for the user, to buy a cable that perfectly fits his camera, it also prevents the unnecessary use of adapters.
