Now since this does have Quick Charge 3.0, it's compatible with a few devices that have that technology. However, it is also backwards compatible with Quick Charge 2.0, Quick Charge 1.0, Adaptive Fast Charging and also conventional charging. So no matter what smartphone you have, you'll be okay to charge it with this wall charger, definitely a good thing.
