I got one a few months ago (backed it early on) and it's great, highly recommended. I love the convenience of just hopping in the car and having Android Auto start without any wires. Plus I can charge my phone with a better charger (my car USB is only 1.0 amp).
Edit: Not sure the adaptor OP is using but I would be afraid of accidentally breaking it off. (AAWireless comes with a 1 foot USB cable)
Edit 2: Found a similar adaptor: https://www.amazon.com/Wpeng-Adapter-2-Pack-Type-C-Extension/dp/B072M9LXVM
AA Wireless is on indiegogo.
This is the adapter - https://smile.amazon.com/dp/B072M9LXVM/ref=cm_sw_r_cp_apa_glt_fabc_AJV14AV91SKPP4SMXNZ7?_encoding=UTF8&psc=1
