An electronvolt is just the energy acquired when an electron falls through a potential of 1 volt, which means
1eV=e×1V=1.6×10−19J
1eV=e×1V=1.6×10−19J
When you lift your 2.5kg2.5kg laptop (a 15-inch Apple MacBook Pro, for example) by a foot, you do work of approximately 2.5kg×10ms−2×0.3m=7.5J2.5kg×10ms−2×0.3m=7.5J which is about 4.7×1019eV4.7×1019eV. So an eVeV is a really low energy scale by everyday standards.
One TeVTeV (a teraelectronvolt) is about the energy of motion of a flying mosquito.
