A:
Generally phones have used chargers that output 1 amp, though due to the desire to charge phones faster, and having larger batteries, some newer phones are using 2.1 amp chargers. Tablets have generally always used 2.1 amp chargers due to the larger batteries, this is why this model is labeled the way it is. If your phone is capable of using a 2.1 amp charger then this model will work fine with your phone.
