Is it possible to detect two inputs at the same time?

I'm making a charging system that includes being able to sense things. I have a key combination and whenever I hold the two keys required it works fine, but when the player lets go of the keys the animation for charging is bugged and although I let go of both keys (at the same time) it still charges.

My question is if it's possible to detect two inputs at the same time? Especially for InputEnded.
