Why is Powergirl only as strong as Supergirl?
Powergirl is age 27-28 and Supergirl is age 16-17. Powergirl has had her powers longer than Supergirl has and yet, they are only almost as strong as each others.

That's because she's from Earth 2. Kryptonians from Earth 2 are not as powerful as their Earth 1 counterparts, and are subject to basic necessities like needing sleep, food, and water to live; whereas Earth 1 Kryptonians get their energy entirely from the sun and so they don't need any sleep or nutrients.
On the plus side, Power Girl is immune to Kryptonite from Earth 1.
