Checked my new car's build quality. It's generally okay. No obvious red flags. The roof glass may shifts slightly, leaving about 1mm uneven gap between left and right. But I had to see the alignment very carefully to note the difference. All functions that I tried works well. I found that it's easy to leave rear left door ajar if I do not close it with elevated force.
My Autsin build car only comes with rear trunk cover, J1772 adapter, and a license plate holder. No matrix light, no mud flaps. I turned on sentry mode and it drained 16 miles battery overnight. More than I expected.
I already have a J1772 charger at home. So I used the adapter to charge it. I found that I can only unplug the J1772 charger and the adapter still on the car's charging port. (the adapter was locked at the time when I try to unplug the whole assembly.) Then the charger door closed automatically, with the adapter blocks the full closure of the door. Then I had to force the door fully open again to remove the adapter and make the door close completely. This is annoying. Probalby I did not know how to do it correctly. Any suggestions?
