Fusion Core locations in Fallout 4 can be found on this page. Fusion Cores energize Power Armor for a finite amount of time and may also be used as ammo for the Gatling Laser.

Fusion Core Information

  • When your Fusion Core powering your Power Armor is empty , you will be unable to use V.A.T.S. or Power Attacks and will move at a reduced rate. You will get a notification when you are running low.


  • Fusion Cores usually last around 30 minutes. Energy consumption depends on your actions and if you do things like sprinting it wil go down faster.
  • The Nuclear Physicist perk increases the duration by 25% (Rank 1), 50% (Rank 2), 100% (Rank 3)
  • The Repair Bobblehead permanently increases the duration of fusion cores by 10%.

Where to Find/Location

IMPORTANT NOTE: Any fusion cores found inside of containers like ammo boxes and steamer trunks are random spawns. For purposes of posterity they can be listed here, in the event that they may only randomly spawn in specific locations. If you are listing a location, please specify whether it is from a container or from a static location.
