Jane is nowhere near as powerful as Alec. I'm always surprised when people say they're equal. One on One vs. any vampire but Bella, Jane & Alec are pretty much equal. Jane may have a slight advantage in this situation, since her power comes on instantly, but if Jane fights 2 vampires, she dies. Whether Alec fights 2, or 5 - as long as one of them isn't Bella, they all die.
