Polyfuse and power problems

[whenness]

Just recently I bought a pi, completely unbeknownst to the dangers of high voltage on a 5V board.
I wasn't really sure whether or not I needed a specific charger, so I used an android-esque charger that was originally purposed for
a high-end speaker. In retrospect, I realize that it drew an immense amount of power.

I only plugged it in a few times, and momentarily at that. Once I realized that I needed a purposed charger with 5V, I went out and bought one.
Now that I have the proper power source, when I plug it into the board there's a constant red light near the power label, and no light at the OK label.

I'm fairly sure it has nothing to do with the micro sd, as I have vetted it and it seems fine, it's in the correct format and contains the right files from NOOBS. I'm confident I've triggered the pi's polyfuse from the initial power mixup, what can I do to reset the fuse or somehow cut my losses and recover the pi?

I'm hoping I haven't bricked my pi or have to wait ages for its fuse to reset.

May I have some suggestions for recovering my pi?

If you have a RPi4 then it does not have a polyfuse.
If you see the red Power LED then the polyfuse is not blown.
Polyfuse should reset itself in a few minutes. Overnight should be plenty.
The android phone power supply likely would not damage the RPi. What are the voltage and power ratings?
Have you gone through the boot problems 'sticky'?

The "OK" label makes this sound like one of the first model Bs. All the newer Pis have "ACT" instead.

If it is the polyfuse, then just leaving the Pi powered off for 24 hours should fix it.

Any half-decent "charger" or Power Supply with a micro USB plug should be suitable for powering a Pi 1B.

If you are using a micro SD with that model, I am going to assume you are using an adaptor, as the early models used a full size SD card slot.
