THE EVOLUTION OF QUICK CHARGE

While smartphone designs have evolved to utilize higher capacity batteries alongside larger screens, USB charging was limited to 5V and 1.5A (7.5W). Quick Charge 2.0 was introduced in 2014 to overcome this limitation by enabling supported devices to accept a higher charge level when paired with a Quick Charge compatible charger. Quick Charge has continued to evolve, making the charging process even faster and more efficient, while ensuring a safe charge that protects battery life.

Quick Charge 3.0 was introduced in 2015 to sustain high power delivery for charging while also making sure that power transfer was as efficient as possible. The latest evolutions, Quick Charge 4 and 4+ will be universal, allowing them to work with any fast charging-enabled device.
