Slow charge rate at a Tesla Supercharger station

[F150Driver]

I tested my A2Z adapter at a Tesla Supercharger station, and even though the app lists the charge rate as 250 kW, my car only reached a maximum of 92 kW.
The battery was warm after driving, and the charging started at around 70% and ended at around 80%.
I expected speeds much closer to 250 kW, but the charge rate remained low. Any idea why this might be happening?

I think Elon didn't want you to have high speed charging.
Joking, haha!
Lighting rarely goes up to 180 kW. Don't expect more than that.

The temperature of the battery, its level of charge, or the adapter's compatibility with your vehicle could have all had an impact on the charging pace. The app displays 250 kW, however actual conditions may cause charging speeds to be lower.
