What is an Electron Volt? - LD Industries Physics 30

What is this weird eV symbol next to this number? Is it voltage? Charge? Energy?
In this video, LD shows you not only what an electron volt is, but gives an example of how to use it in a physics problem.

O are they acting like a quantum battery. No one answers these questions. Does it loose its electron votage when it reaches the other side?
