It might be defective. Many air poppers have dual elements and I've heard stories of poppers with one element failing or being stillborn; perhaps that's what is ailing yours.
A voltage difference would affect the maximum temperature but it would have to be quite large to have the effect you're observing. Unless your other roaster uses something other than a purely resistive loaded heating element it's performance would also be suffering.
They could have lowered the temperature deliberately but I'd think at that point it would also make a poor popcorn-popper. You might want to try running some corn through it and see if it can even pop it, or if it takes unusually long to do so.
