While Fallout 4 has definitely achieved critical acclaim and tons of love from the gaming community as an open-world action RPG, many Vault Dwellers are roaming the Boston Commonwealth and still in need of supplies, especially when it comes to Fusion Cores for the T-60 power armor. Since developers didn't give fans the option to recharge the batteries for the power armor, characters' suits constantly run the risk of losing juice right in the middle of crucial moments in the game.

Fallout 4: All Main Story and Faction Quests
There's a ridiculous amount of content for Fallout 4 players to sink their teeth into, with over 50 main story missions and plenty of side quests.

Of course, players can spend bottle caps for Fusion Cores at vendors all across the Wasteland, like Arturo in the Diamond City Market, but the map is simply too vast for fans to expect their T-60 gear to hold a charge getting to each in-game retailer. The following list of locations in Fallout 4 shows some of the best spots to scavenge for Fusion Cores.

Updated April 16, 2024, by Tom Bowen: Power Armor can be incredibly useful when it comes to surviving the harsh and hostile setting of Fallout 4. As those new to the wasteland will soon learn though, using Power Armor requires Fusion Cores: a rare and valuable resource that can be somewhat difficult to come by. There are certain locations where Fusion Cores are guaranteed to spawn, but some of these are guarded by powerful enemies or require players to solve a puzzle or two in order to get their hands on the prize. To help Sole Survivors on their journey, this guide will highlight some of the best places to find Fusion Cores in Fallout 4 and its DLC expansions.

Fallout 4 Fusion Core Locations (Multiple Cores)

Dogmeat and the Sole Survivor in Fallout 4

The Commonwealth is the regular, main area in Fallout 4 that players can access without having any DLCs downloaded. This area is extremely big, and given its size, there are multiple Fallout 4 locations where players can go looking for fusion cores. As such, only areas with more than one fusion core have been included in the table below. Beneath the table, a shorter list with easy Fusion Core locations where a single core can be found has been added for players in dire need.

For players who have fully explored the map, or do not want to go too far out of their way, certain groups and characters have fusion cores that the Sole Survivor can take.

  • Vendors who sell ammunition, such as Alexis Combes in Vault 81 and KL-E-0 in Goodneighbor, can sell around 5 fully charged fusion cores.
  • Robert MacCready can give the Sole Survivor fusion cores upon starting conversations with him as a companion.
  • Erin Combes in Vault 81 will reward one upon completing Here Kitty, Kitty.
  • Sentry Bots have one or two in their inventories upon being defeated. An already defeated one can be found in Hester's Consumer Robotics.
  • Can be pickpocketed from Brotherhood of Steel members.
  • Can be pickpocketed from Atom Cats.

Far Harbor Fusion Core Locations

Nuka-World Fusion Core Locations

Fallout 4 Nuka World

Nuka-World is the final big DLC that Fallout 4 received, and it's fantastic for farming a bunch of fusion cores for players favoring a power armor. The Nuka-World junkyard in particular is a great spot to head out to, as it has the most fusion cores in the entire game. Since there are fewer sub-locations in Nuka-World, all locations with even one fusion core have been featured in the table below.
