USB 2.0 VS 3.0 Charging Phone | ZONSAN

2023-01-03 USB 2.0 has a maximum data transfer rate of 480 megabits per second (Mbps), while USB 3.0 has a maximum data transfer rate of 5 gigabits per second (Gbps). While USB 2.0 is capable of charging a phone, it may take longer to do so compared to using a USB 3.0 port. This is because the higher data transfer rate of USB 3.0 allows for more power to be transmitted to the device, resulting in faster charging. However, the difference in charging speed may not be noticeable in all cases, as it can also depend on the phone's battery and charging circuitry.
