What does the specification chargers usually mean like Output: 5V=2A or 5V=6A MAX ?

Question

I was looking at my One Plus Warp charger and I saw that the output says 2A or 6A at 5V. What does this exactly mean?

Edit: I wanted to add some more info. When I charge my brother’s mi phone(screen displays fast charging when I use mi charger at 5V and 3A) from my charger it doesn’t show fast charging. So does the warp charger operate at 3A when it is charging the mi phone or at 2A?

Very simple it means that the power supply is putting out a 5 volt supply and it can provide either 2 amps or 6 amps output at 5 volts.

I’m guessing that the adapter either has a switch to swap between the 2 ampages, or the higher ampage is only available to items that have the circuitry to enable the higher current draw
