Have you used it yet on a camping trip?
I've read mention of usage and it was a bit annoying as the engine would kick in.
If we can't manage at what percentage the engine should kick in it could be a nuisance.
Curious because that's exactly how I was planning to use mine.
My brother in law crashed his Hyundai IONIQ after being one of the early adopters. it took 9 months before he got the car fixed due to lack of spare parts etc.
It is not uncommon for repair components and sometimes expertise to take a while to get 'out there'.
