If the power supply always delivers 3.0 amps, no matter what you connect to it, then it would work. However, there are some micro USB power supplies that try to be 'smart' and will only deliver higher amps if they are connected to a phone that they recognize. If they connect to an unknown device, they might throttle the power down to 0.5 amps (500mA).
The other issue is whether the power supply is designed to deliver 3 amps all of the time without overheating, or it is meant to deliver 3 amps as a peak amount. It really depends on how well it is made.
