Charging Joysticks With Wall Adapters - Question About Power

Quick Question . . . I would like to use a wall USB adapter to charge my joysticks. Some of these adapters offer 1.0 and others 2.3. What would be the correct power levels to do this. (I tend to do my charging overnight).

Also, can anyone suggest a decent unit that could handle about 6 joysticks each?


The VEX IQ Controllers only need a standard USB port capable of 500 mAh (0.5 Amp) to charge their battery, so both 1.0 Amp and 2.3 Amp USB adapters will work. There is no difference in charge time for using USB wall adapters that provide greater than 500 mAh.
