What adaptor would you recommend, that could be bought on BG/GB/FT?

A compatible PD2.0 (Power Delivery) or QC3.0 (Qualcomm’s Quick Charge 3.0) adapter.
QC3.0 is quite common and you find it without difficulty.

That’s correct, but still a small warning about car chargers.

The max input of the charger is 3A @15v.

This charger is QC3/QC4 but only outputs 2A @12v. (24 watt)

So:
XTAR can handle 45 watt
Car charger maxes out at 24 watt

2 cells charging at 4.1 amps (possibly) require 34 Watt.

So… while QC3 this charger isn’t powerful enough for the XTAR.
I have charger of this brand to charge my OnePlus with Dash charge in my car. It works great until outdoor temps reach the upper 80’s then it suddenly charges much slower. Overheating I guess.
So while roma58 is 100% right QC3 chargers are easily to be found, it’s not so that all allow you to reach the full potential with the XTAR.
Just my two cents.

Just sharing…
