Rather interestingly, I have an Anker power bank here with a USB A output and 
the specification of its output is:

5V⎓3A, 9V⎓2A, 12V⎓1.5A (PowerIQ 2.0)

So we see it will output 9 Volts at 2 Amps which gives us 18 Watts.  Now my USB 
power bank also outputs 9 Volts at 2 Amps again 18 Watts.

Here’s the interesting part.  The USB C charger will charge my iPhone from flat 
to 50% in half an hour.  The USB A power pack charges to around 32% in the same 
time.

So although both power packs claim 18 Watts output using a USB A to lightning 
cable the iPhone does not accept 18 Watts of charge but with a USB C to 
lightning cable it does.
