I assume you mean the power to attract things. It is for the same reason that our Sun or a galaxy (for example) is powerful; and the reason is the amount of mass. The more mass an object has, the greater its gravitational attraction. Known black holes have masses between a few times the mass of our Sun, and - in the case of some supermassive black holes - about 20 billion times the mass of our Sun, so their gravitational attraction is correspondingly strong.
Assuming you mean "power" as the word is used in physics (energy per time unit):* An extremely small amount of power would be emitted, due to Hawking radiation. The larger the black hole, the smaller the power of this radiation.* On the other hand, if matter falls into the black hole, such matter can temporarily emit a lot of power; in fact, quasars (which contain a black hole) are the brightest objects in the Universe. * Finally, if two black holes merge, for a few seconds or so, they emit more power, in gravitational waves, than the power output (in light and other electromagnetic radiation) of all the stars in the entire observable Universe.
A lot would depend on the mass of the black hole. A black hole the mass of an asteroid (should any of that size exist) would probably enter the Solar System and get back out again, just like any comet. We might not even notice it. A black hole the mass of a star would probably cause a lot of disruption in the orbits of the planets.A lot would depend on the mass of the black hole.

No, it is not currently possible to control or manipulate the power of a black hole. Black holes are extremely massive objects with such strong gravitational forces that even light cannot escape from them, making them one of the most powerful forces in the universe.
a black hole cannot be ovserved, so it could not be discovered. a black hole is created when an extremely old star implodes on itself causing a distortion in space, making a hole with suction power so strong it can even trap light.
That depends a lot on the mass of the black hole. The smaller black holes will evaporate more quickly. A stellar black hole (a few times the mass of the Sun) is expected to live approximately 1066 years, while a supermassive black hole might survive something like 10100 years before evaporating completely.
If you mean its force of attraction, that's related to its mass.
When an atom is smashed in a black hole, its particles are torn apart due to the extreme gravitational forces. The subatomic particles are then absorbed into the black hole, adding to its mass and energy. The energy released during this process can contribute to the black hole's growth and power its intense gravitational pull.
A Schwarzschild black hole is a non-rotating black hole. The Kerr black hole is a rotating black hole. Since the latter is more complicated to describe, it was developed much later.A Schwarzschild black hole is a non-rotating black hole. The Kerr black hole is a rotating black hole.

Running into a black hole is practically impossible because the nearest black hole or soon-to-be-black hole is about like millions of light years away and black holes can only attract things from a few billion km away. You may think that's a lot but believe me, a million light years is way more than a billion km.
The ending first: We don't know. Please re-read that. OK, what are the conjectures? A Black hole leads to another, somewhat parallel universe. A Black Hole leads "nowhere". A Black Hole leads to a different type of singularity. A Black Hole leads eventually to another "Big Bang" in another dimension. A black hole leads to a parking lot in Gelsinkirchen, Germany. There are many more. Please re-read the first sentence.
The power source of a quasar is a supermassive black hole at the center of a galaxy. As material falls into the black hole, it forms an accretion disk that releases immense amounts of energy, generating the intense radiation emitted by quasars.
A black hole originated as a star, that is, the star converted to a black hole.
