Mine is 118.5V.  GE is as good as anyone at working around grid issues, 
and I 
think most grids fall in the 110 to 125V range.  I assume they expected 
some 
people to use 50' extension cords of 16 ga (I wouldn't...) so the charger 
probably 
can work from 105 to 125 V range.  I think you will just charge a bit 
faster than 
the rest of us.

Larry, any suggestions for an ET charger when the grid voltage is typically
in the 122-125Vac range?  Or should I just complain to the utility?
