If you perform actions that drain your AP meter such as sprinting, holding your breath while aiming, or using the V.A.T.S system, then it loses charge even faster.įusion Cores can be found in a variety of different locations. A fully charged core can only function for twenty minutes before it completely depletes. They also have a relatively short lifespan.

They are found within the ‘Ammo’ tab of your inventory, so they do not have any weight. To start with, it should be mentioned that Fallout 4 technically classifies Fusion Cores as ammunition.
