Kinetic Capacitor is a unique augment belonging to Rush, which gives her +1 KO damage and +1 armor piercing to melee attacks while she is sprinting. The bonuses apply while Rush has the “sprint” ability enabled, including during the enemy turn if she makes an ambush after ending the player turn with “sprint” enabled.
The bonuses from Kinetic Capacitor do not apply to ranged weapons, and do not apply while Rush is not sprinting, even if she had previously sprinted in the same turn. Note that the in-game tooltip text for the Kinetic Capacitor augment is misleading, as it does not clarify that the bonuses only apply to melee attacks.
