In-game pickup line
“Quicker charge”
Mechanics
What 9 Volt does
- Active items effectively need one fewer charge to become usable.
- Picking up 9 Volt immediately charges Isaac's current active item.
In a run
Practical note
Its value grows when the active item is something you want to use repeatedly.
