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.


  • With no perks or Bobbleheads pertaining to the cores, Fusion Cores last  20 minutes real time and 10 hours game time. Energy consumption depends on your actions and if you do things like sprinting it will 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.

      I feel like some idiots are updating this thinking that Fusion Cells are Fusion Cores... They are NOT the same thing. Also I've heard from several sources on the internet that there are at least some Fusion Cores in Weston Water Treatment... Yet I've been through it several times and not found anything. Anyone else found them and know where they are? Any help would be appreciated.

        There's a fusion core under mystic pines NE of Lexington. Unlock the advanced lock and go down the stairs.

          You can recharge cores in the generators that you find them in sometimes. The generator in the museum of freedom where you find your first ever core and power armor works for this. Just put a drained core in the front and press the button on the side to charge it.
