Newer made M18 Dual Bay Superchargers charge at 19 Amps total?

I recently purchased two M18 dual bay Superchargers at my local Home Depot. One of the two was made in March 2024 (according to the serial number) and the other was made late November 2024. Upon looking at the Owner's manual on both, the newer unit states that it charges one battery at 12A and the second at 7A (instead of the expected 6A) for a total of 19A. The label on the back of the unit also confirms 19A total output on the newer unit and 18A total on the older.

So newer made Superchargers are even faster than the older units? Can you guys check your Superchargers?
