I have a MacBook Pro M1 2020 and I wanted to charge my iPhone using it, wondering what the speeds are like if I was to do so, I can’t find out anywhere on the Internet, what the output power is for USB C ports. Finding out this would be really helpful because then I can know if I can fast charge my iPhone or not.

It appears that iPhone fast charging takes advantage of USB-C Power Delivery.

How much power a 13" M1 MacBook Pro would be willing to offer to peripherals, via its USB-C ports, would be up to the MBP. Just as chargers vary in how much they're willing to offer, so do host USB-C ports on computers.

Since you already have the M1 MacBook Pro, and the iPhone, perhaps you could do your own experiment. Let the iPhone's battery charge run nearly out. Charge the MacBook Pro to 100%. Then connect the two and periodically check the iPhone's charge level. That should give you some indication of how long things might take in practice – whether you ever get the answer to the technical question, or not.
Just done that have a iPhone 13 Pro, has roughly taken around 2 hours to full charge if someone can probably do the Maths on that to figure out the wats
