Why Does It Feel Like a 'Not Sure 20,000mAh'?
Understanding Capacity Loss
All the power banks could only supply 60%-70% battery to other devices, since around 30-40% of the capacity is lost in circuit heat and voltage conversions.(Actual Capacity ≈ 12000-14000mAh)
(PowerBank Rated Capacity × 0.6) ÷ Device Battery Capacity ≈ Number of Charges
eg. (20000mAh Powerbank × 0.6) ÷ 3279mAh iPhone14 battery ≈ 3.6 charges
Full Recharge Time
It depends on the power of the wall charger used: 18W fast charger - 6hrs; 5V/2A charger - 10 hrs; 5V/1A charger - 20 hrs

What is the output capacity?
20000mAh is a value what shows a battery capacity. It is not 100% correct but to simplify it I would say it is an equivalent of an amount of energy a battery can hold. It does not matter what current you use - 1A or 2A as long as it is within of battery operational range. In both cases it is the same amount of energy what can be provided by battery. You just will consume it faster or slower, but energy amount still the same in both cases.
It is important to understand that energy saved in a battery is used not only to charge something. There is a chip/convertor inside, what will take some amount of energy needed to produce a desired output current/voltage, so some energy will be used to warm up an air outside of that chip :) If that conversion is not efficient, it will waste a lot of energy and overall efficiency rate will be low. So if is capable to charge iPhone 11 Pro only 4 times before full discharge, then it means 3050*4=12200mAh of energy used to charge iPhone, while 20000-12200=7800mAh will be wasted just to warm up the air around. It explains why it shows 20000mAh (battery capacity) in a description, but only 12200mAh used to charge your device. Also, in common case the more the current is, the less efficiency rate will be. It means with 1A current you may charge iPhone 4 times, however, if you take 2A, it probably will be enough only for 3 charges. (all numbers are approx, just to demonstrate an idea).
So, if your power bank is warm\hot during charging a phone, it means it uses low quality\low efficient convertor, what is wasting a lot of energy saved in a battery.
Is the usb c port for input only or can it be used to charge a phone with rapid charging with a usb c to usb c cord?
Agreed with getkyle. The seller's response is incorrect. It can charge up to three devices at once. It can charge from both the two standard usb-a ports as well as charge at PD and QC standard through usb-c. You can also charge the battery bank through the usb-c port so it acts both as in/out and it is labeled as so on the device
Does this power bank support fast charging?
Yes, it can support fast charging for your phones. It can fuel your iPhone 14 up to 61% in 30 minutes. You may have more time to enjoy yourself!
