  • Both power armor and gatling lasers benefit from this perk, as both use fusion cores.
    • This perk also affects the drain rate the jet pack modification has on fusion cores.
  • This perk is less useful for those who have a lot of fusion cores in their inventory, and taking the perk can be skipped by either simply farming fusion cores from a power plant or from crafting with flux.

Behind the scenes

There are two cut ranks of this perk in the game's data. The fourth rank made fusion cores last 80% longer, while the fifth rank made fusion cores last twice as long, which effectively became the current third rank.
