Fusion Core Locations | Fallout 4

Fusion Cores are fuel cells for Power Armor in Fallout 4. They are required for running the armor – if you’re out of juice, it will just stop working.
This guide will show you where to find fusion cores in Fallout 4.



Fusion cores can be replaced without leaving the suit – you’ll just hear a sound and the core will replace itself with a spare. A full core will last for about an hour and a half, if all you do is run and walk.

Fallout 4 Fusion Core locations

Almost every Power Armor will come with a somewhat charged fusion core, so you usually don’t have to worry about starting it. There’s a gauge in the lower right corner of the Power Armor HUD, showing how much fuel you have left, and how many spare cores. They’re not rechargeable, so you’d best carry a few of them with you at all times.

Traders that sell Power Armor parts usually have some fusion cores in stock as well – the Brotherhood of Steel and Atomic Cats shopkeepers are among them. We still don’t know if you’ll have to be on good terms with them to use these shops, or will they sell to you regardless of status.

Always thoroughly search around Power Armor stations, and in camps where you fight enemies using these suits. They need the juice, so there’s a good chance some of it is just waiting to be found.

Check out Power Armors Locations that we have found so far.


  • If you break into the merchants’ houses in Diamond City, you’ll get plenty, like 5-9 in a few houses I looted (thanks a)
  • If you sell Fusion Cores before they run out, you will get enough money to buy a new one.
  • There is a glitch where you can steal unlimited power cores from an NPC. When you steal the first one, NPC will try to get out of the armor. In that moment just quicksave and reload. NPC will appear again with a new set of armor and a new power core. You will have to wait a few seconds to be able to pickpocket him again. (thanks ThePsuedoMonkey)
  • Crashed Vertibird (Covenant Lake) – In the lake under the water, near the Vertibird wreckage, look for T-51 Power Armor.
  • Graygarden – From the Graygarden head east. Location of this armor is on a highway bridge, next to an airplane wing. Before you can reach it, you have to find an elevator, that will take you to the top. Location of the elevator is marked on the screenshot.
  • Sanctuary Hills – Behind the Red Rocket gas station south-east of SH, in a Mole Rat den.
  • Robotics Disposal Ground – In a military chest next to a broken robot in RDG, north-east of Sanctuary Hills.
  • Concord – In the hole from which the Deathclaw emerges during When Freedom Calls.
  • Fort Hagen – One of the generators in Fort Hagen has a core you can steal.
  • Wreck of The FMS Northern Star – On the ground next to the ship. It’s guarded by relatively strong Mirelurk Razorclaws.
  • Mass Pike Interchange – The armor is near construction on the bridge.
  • Military Armor Transport (North Wilderness)
  • Military Armor Transport (Lexington)
  • Military APCs (near Poseidon Energy Turbine #18-F)
  • Military Checkpoint (Cambridge Outskirts)
  • Inside Fiddler’s Green Trailer Estates
  • Military Convoy (Training Yard) check the armor inside the wagon, near Finch farm.
  • National Guard Training Yard
Work in progress.

      There are a total of three at the robotic disposal yard. Turn on the sentry bot and kill it for the last two.

        you can tell him to self distruct with the terminal in the office

          O
          Oliver

          Yeah, go to the terminal and choose the play tape option to activate the sentrybot, then once it’s up and running go back into the play tape option and choose self destruct. After self destruct the sentrybot wreckage will have 2 fusion cores that can be looted along with some other useful stuff like a military-grade circuit board.

    There is also one in the area of the first quest you do with the brotherhood.The one against the Synch you and the Paladin.But you cant take it because you cant end the quest if you remove it, so you have to return there later and take it.

      Beau

      you actually can, i’ve done that quest and i was able to take the fusion core.

      The one down in the bottom of Arcjet systems? I just took it and ended the quest fine. Maybe your game glitched. You have to exit the building via the elevator to end this quest and the game often glitches when using elevators. Just ensure to save the game before leaving the building and then reload and try again if it goes wrong.

    Can you craft fushion cores

    D
    Dentka

    For me, the big robot at Robotics Disposal Ground is glitched, so if you go inside the shed and activate him through the terminal you can just attack him until he dies, he doesn’t fight back unless he wedges free (I think this happens when you melee him a lot or use a lot of explosives) he dropped 2 fusion cores for me

      J
      joe

      or u can just go back to the console and set the self destruct 🙂

    There’s also one at Greenetech Genetics, as soon as you take the elevator to the top floor, head for the staircase. Don’t take the stairs, there is a door to the left that you can lockpick to open and get a fusion core from that room.

    The Mayoral Bunker has two. One in a crate on the first of second floor, then one in the generator room next to the gym. There’s a mini nuke there as well. And a heartbreaking halo tape. Just be prepared for an onslaught of Synth’s after you grab the mini nuke and core.

    Join the brotherhood of steal early in the game and you can still go back to the institute later but the brotherhood gives you a set of t-60 power armour and do a couple brotherhood quest and you will get access to the giant blimp and explore the giant blimp the whole thing and there are fusion cores laying around everywhere up there for free to I have close to 10 fusion cores just from exploring the blimp and doing brotherhood quest. GOOD LUCK ! Take this advice !
