Using 400Hz power is risky, because the current in the RFI bypass
capacitors will much higher than normal. The leakage current through the
capacitors to the output and other accessible parts will be high,
possibly high enough to be a shock hazard. Running a 50-60Hz product
from 400Hz power may also cause early failure of those capacitors.

Follow the charger's marked input frequency rating, which almost always
will be 50-60Hz. A small variation for the tolerance of a
motor-generator is acceptable, but 667% of the maximum rated frequency
is no small variation!
