I vaguely remember that someone discovered a hidden menu or steps not in the user manual for this (about 3 years ago? On this forum)
I think Blink actually remotely reduced the Max when there was a concern that some of the early L2 handles may not have been properly manufactured to handle the newest EVs that had greater than 3.3 kW chargers. Concern there might be over heating of the handle.
You might be able to search the forum. I may have printed the steps out but would have to "search my files" to see if I could find it.
