Can Quick Charge hurt my smartphone’s battery?

Quick Charge operates within the design parameters of batteries found in most smartphones. It is just charging the battery the way it is designed to be charged.

Device manufacturers build smartphones with a specific battery that can accept a specific level of charge. The battery size and maximum current of each battery are design decisions made by the manufacturer and can vary from smartphone to smartphone, tablet to tablet and so on.

However, traditional battery charging technology does not come close to the full power requirements of today’s large batteries. Quick Charge is designed to allow device manufacturers to achieve the full rated capability of the batteries they choose while still meeting the performance and safety standards set by the battery manufacturer.

What is the difference between Class A and Class B accessories?

The difference is the maximum voltage. Both Class A and Class B adapters are rated at 5, 9 and 12 volts. Class B adapters go one step further, up to 20 volts. Class B adapters are large enough to charge devices that need more power, such as a notebook computers. Remember, Quick Charge is engineered to deliver only the power needed for the device it’s charging, so a Class B adapter can be used for a smartphone or laptop.

Does it matter what type of charging cable is used with a Quick Charge adapter?

Quick Charge is designed to be connector- and current-independent. Quick Charge is designed to be compatible with a variety of formats, including:

USB Type-A
USB micro
USB Type-C
Proprietary connectors
Quick Charge high-voltage operation is designed to minimize charging issues associated with long or thin cables, allowing for a superior charging experience, independent of cable type or cable current capability.
