No, using a higher amperage (e.g., 6A) does not increase emGuarde™™’s coverage range. The adapter specification of 5V with a current range between 2A and 6A simply ensures compatibility withemGuarde™’s power requirements. emGuarde™™ operates at a fixed power consumption of 0.5 watts, drawing only the current it needs to function effectively. The coverage range is determined by emGuarde™’s design and harmonic frequency settings, not by the amperage of the power supply.
