The Fusion Core is an item in Fallout 4.
Fusion Cores are used as a source of energy for Power Armor.
You can increase the duration of the Fusion Cores by 10% by collecting the Repair Bobblehead at the Corvega Assembly Plant.
The Nuclear Physicist Perk (Intelligence 9 on the Perk Chart) also extends the duration of Fusion Cores.
