I'm trying to find out the current needed to power a Godox MS300 photography flash (Official specs at the end of the page). I'm using the 220V version, and it says that at max power, the output is 300Ws, for which it takes 1.3 seconds to charge. I'm wondering if it's as straight forward as:

\$\frac{300Ws}{1.3s} = 231W\$

And then

\$\frac{231W}{220V} = 1.05A\$

If I'm getting it wrong, is there a way to calculate the current needed with the data given by the manufacturer? Even an aproximate would work.

*1: The modeling lamp has a 150W consumption, but that is a different light than the flash itself.
