Watts and Amps amounts needed for the Square Stand

[MrsBsHoney]

I'm preparing to do an indoor show and the electricity requirements to plug in my square stand (without printer) are needed for the form.  I have three choices, 5 amps/500 watts, 10 amps/1000 watts, or 20 amps/2000 watts.  Each one has a different cost.  which one is correct for my square stand?

First or second would work I think.  Never seen an expo list electrical requirements that way.  I would just call them and say you need a standard outlet.
