That was my assumption also, based on the output of mains electricity chargers stated to be 2 amp; but when charging at the mains the screen is not usually displaying data.
It's the screen leds that draw a lot of power.

They get by with a cig lighter charger. The vibration on the bike added to poor connections available from cig lighter sockets is almost surely the difference for bike riders having charging problems that uber drivers dont seem to have - and is solved by hard wiring.

Below is a quote from an online review for a 3 amp hard wired charger:-
"Just remember that if you want it to charge smartphones or tablets, you have to short the data pins on the USB socket so the device thinks it is connected to a mains charger"
They may be on to something; certainly I didn't do this in my experimentation.
This would be very relevant if the vehicle in question is of the modern variety; the connected device could interpret the signals to mean that it is connected to a computer - in this case, the ECU of the motorbike/car/truck.
