I use the charger with my Model 3 on a red socket and charge at 11 kW. The device works absolutely reliably and flawlessly. I also use it on the road, as Tesla only includes an emergency charger (2.2 kWh).

The battery charger works very well I have a hyundai ionq 5 never had any problems mine completes all the charging and even within the time I expected 20%-80% in about 3h and 40 min.
The only defect is that it doesn't have a switch so every time I have to unplug it or the display stays on.

I’ve been using this charger with a Tesla Model Y for 8 months and it has worked every time.
