There's two major types. The piezo ones where the button makes a loud "clack" and it produces a spark without a battery. There's also electronic ones that run off a battery and produce repetitive sparks when the button is pressed.
Either will work, it's up to you which you prefer to use, though the latter type could take the place of the 110V one more easily and you don't have to hit the button multiple times if it doesn't light on the first try.
