Well, evaporation is simply a conclusion from hawking radiation. The black hole losses energy over this radiation, energy it produces from it's own mass. Since hawking radiation output increases relative to the size of the black hole as it gets smaller, eventually you end up with an explosion. I do believe that Kurzgesagt made a video that details what would happen with a blackhole with the mass of a coin in your pocket (short version: you die)
