Catalysis of the transfer of potassium ions (K+) from one side of a membrane to the other. Catalysis of the transfer of a solute or solutes from one side of a membrane to the other according to the reaction: K+(out) + H+(out) = K+(in) + H+(in). Catalysis of the transfer of metal ions from one side of a membrane to the other. Catalysis of the transfer of a inorganic cations with a valency of one from one side of a membrane to the other. Inorganic cations are atoms or small molecules with a positive charge that do not contain carbon in covalent linkage. Catalysis of the transfer of a solute or solutes from one side of a membrane to the other according to the reaction: K+(out) + Na+(out) = K+(in) + Na+(in). Catalysis of the transfer of a solute from one side of a membrane to the other, up its concentration gradient. The transporter binds the solute and undergoes a series of conformational changes. Transport works equally well in either direction and is driven by a chemiosmotic source of energy. Chemiosmotic sources of energy include uniport, symport or antiport. Enables the active transport of a solute across a membrane by a mechanism whereby two or more species are transported together in the same direction in a tightly coupled process not directly linked to a form of energy other than chemiosmotic energy. Catalysis of the active transport of a potassium ion across a membrane by a mechanism whereby two or more species are transported together in the same direction in a tightly coupled process not directly linked to a form of energy other than chemiosmotic energy.
