Filling your tank with fossil fuel is 5 minutes wall clock but also 5 minutes where you can't do anything else. If you need to pee or eat that's a few more minutes. Filling your battery might be longer 10-15 minutes, but (at least for Tesla superchargers) about 20 seconds of your time, for the remaining 10-15 minutes you're free to do whatever you want.
