A:AnswerIT adjusts per your device as per USB Power Delivery specifications. Believe it or not, there's a microcontroller in the power supply that communicates with your device to determine what it can take.
The supported volts/amps combinations are:
5V at up to 3A (15 Watts)
9V at up to 3A (27 W)
12V at up to 3A (36 W)
15V at up to 3 A (45 W)
20V at up to 3.25 A (65 W)
So, if your device can take 20V and at least 3.25A, it'll charge at 65W. Most phones can't take that much - check your phone manual. Most likely this charger will charge your phone at the max rate it can, and other devices (laptops) at 65W. Don't worry about the charger damaging your device - the USB standards organization created a standard in 2007 that requires any devices certified as USB to only charge at the rate both devices can handle without damage. Don't try to use this adapter on a very old (pre-2007) device using an adapter though!
