Why does everyone think the voltage is 110/220??

If that actually was the voltage you had in your house you'd be very
unhappy. The nominal voltage is 118/236 with a +/- 5% range so you can
see that 110/220 is actually outside the acceptable range.

actually in my travels, ive seen 90-140 volts nominal for the
"standard" 110V outlet. so it is a bit more than 5% tolerance
