Why is it that my charger that has a rating of 100-240 volts and 1.3 amps can handle/input more watts at a higher voltage when doing the formula watts=volts x amps?
In addition, why can't it, at a lower voltage, handle the same amount of watts that it can at a higher voltage?

Simply put, it does not.
It will deliver its rated output while being able to use a supply within the range specified.
If the voltage is at the high end (230V) then the required input current will be lower, if the input voltage is at the low end then the current goes up.
