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.
