The difference between apple data cable lightning-usb and USB-c lightning

1. Difference of charging speed: The highest transmission rate of USB-C port is 10GB per second. However, Apple said that the USB-C port of the new lighning has a maximum transmission rate of 5Gbps. The maximum output voltage is 20 volts, which can speed up the charging time. The USB-A model has a limit transmission rate of 5Gbps and an output voltage of 5 volts.

Second, the difference between two-way transmission: unlike the old USB port, which can only transmit power in one direction, the power transmission of USB-C port is two-way, which means it can send power in two ways. Therefore, users can not only charge their mobile devices with notebooks, but also charge their notebooks with other devices or mobile power sources.

Third, the difference between universal functions: the USB-C port of the new lighning can transmit data and charge, and can also be used as a video output port to link external display devices.

Fourth, the difference of terminal interface: USB-C lightning port is 0.83 cm long and 0.26 cm wide. The old USB lightning port 1.4 cm long and 0.65 cm wide is out of date. This also means that the end of USB-C data cable will be one third of the size of standard USB-A data cable plug.

Fifth, the difference of backward compatibility: USB-C can be compatible with the old USB standard, but users need to purchase additional adapters to complete the compatibility. Apple said that not only will Apple officially sell adapters, but third-party companies can also authorize production. However, lightning-usb is not compatible with USB-c lightning.
