I need one now, or else my lights will get turned off. I just need it to scrape by until my paycheck in 2 weeks. What is the safest, best one? That gives the money quickly?

Even if there was one, you are only making your problems worse by using them. You'd actually be better off to let them turn the lights out. That would teach you to manage your money better so this wouldn't happen again.

I have to believe a walk in store could be faster and a little bit less risky, though they are charge obscene interest rates.

There are none. Try getting some leniency from the power company. If you had a credit card ...

or emergency savings ... or family nearby ...

None. Sell your damn phone which you can't afford and close your account.
