would putting a 4 -6 outlet plug be better or even needed? I’m not sure if the high end outlets typically go up to 4 or 6.
One standard receptacle has two outlets. If you need 4 or 6 outlets you’ll be using, respectively, 2 or 3 receptacles. You’re using the same receptacle "unit" regardless of how many outlets.
Multiple receptacles in one box should be bussed rather than daisy-chained. Receptacles should always be wired at their screw terminals, NEVER backstabbed (although for some unfathomable reason backstabbing is still Code-compliant in the US).
Enjoy!
