The Fuel Cell is an item in Risk of Rain 2.

The item grants an 1 (+1 per stack) additional equipment charge per stack, and reduces equipment cooldown by 15% (+15% per stack).

This item stacks linearly with additional equipment charges, and exponentially with equipment cooldown.

Notes

  • The maximum amount of possible equipment charges is 255, with 254 Fuel Cells.
  • If extra equipment charges are ready and then the player loses Fuel Cells (e.g. by using a Scrapper), the extra charges will remain until used up. However, those extra charges will not recharge once used, unless the player collects more Fuel Cells again.

Math

The equipment cooldown is determined by the formula cooldown * (1 - 0.15) ^ amount

    Dramatically reduce Equipment cooldown... BUT it automatically activates.

    Reduce Equipment cooldown by 50% (+15% per stack). Forces your Equipment to activate whenever it is off cooldown.
    , refer to the math on that page for the cooldown formula and values, by adding the amount of Fuel Cells & Gestures, as additional Gestures share the same reduction as Fuel Cells.
