Catalysis of the transmembrane transfer of a potassium ion by an outwardly-rectifying voltage-gated channel that produces a transient outward current upon a step change in membrane potential. Catalysis of the transmembrane transfer of a potassium ion by an outwardly-rectifying voltage-gated channel. An outwardly rectifying current-voltage relation is one where at any given driving force the outward flow of K+ ions exceeds the inward flow for the opposite driving force. Catalysis of the transmembrane transfer of a potassium ion by a voltage-gated channel. Catalysis of facilitated diffusion of a potassium ion (by an energy-independent process) involving passage through a transmembrane aqueous pore or channel without evidence for a carrier-mediated mechanism. Catalysis of the transmembrane transfer of a cation by a voltage-gated channel. A cation is a positively charged ion.
