Yes, classic trade off, low cost but slow direct from China, or many more
$$$ but fast from a local supplier :-( .

Not limited to tablets that use USB-C. The 7" 2018 Amazon Fire tablet that
I successfully got running has USB Micro-B (ie: I use a power supply that I
used to power a Raspberry Pi 3) to recharge that tablet. You will need to
get (at least with the device I got) a cable to go from USB Micro-B to
USB-C (I had two USB cables I could/did connect together to achieve this
and earlier today I bought a dollar store USB Micro-B to USB-C cable (the
later not yet tested)).   Only semi-odd bit was one needs to jump through a
few hoops to get Google Play Store installed. Once Google Play Store is
installed, installing "USB Camera Standard" is very straight forward.

All the best.
