Red Bull is probably the most famous, but is actually less caffeine than coffee. (30mg.100g, vs coffee Americano with 40mg/100g)
There's an energy drink called Ammo with 570mg/100g, the equivalent of 14 cups of coffee.
There's also new chewable caffeine produces like Foosh Energy Mints, with an insane 5,555mg/100g (=139 cups of coffee). Presumably they figured people would just pop one mint and not sleep for three days before popping another, as opposed to tossing them back like popcorn.
