You could go with an electrolyte blend, but there are also a few staple products out there that cover electrolytes as well as other daily staples like creatine and betaine. A product like Powermax XT would be a great option IMO. It contains sodium phosphate, potassium phosphate, and glycerol which can deliver a nice pump. Powermax XT also contains creatine and betaine for strength and recovery, as well as COP and Amentoflavone which can both help with strength and performance.
