In this case, Lightning cables are not suitable to fast charge because its current is limited in 2.4A. That means Lightning cables allow less power to deliver to the powered device under the same voltage. The maximum current the Lightning cable carries is 2.4A while the USB-C cable is 3A and can be up to 5A. Power DeliveryĪnother big difference lies in the power delivery rate. Wireless transfers or access to data through cloud servers is more common nowadays. Furthermore, you don’t have to use a cable to transfer data. It’s not usual to transfer big data files via mobile phones or other devices. In fact, an update on the standards of Lightning cables has not been seen in over eight years.Ĭlearly, USB-C is much faster than Lightning, although some believe that Lightning is not necessarily worse simply because it’s slower. No one really knows exactly what speed Lightning can handle as Apple doesn’t release all specifications. Although there were reports that the newer model of the Lightning connector supports a USB 3.0 host, you can only find it on some iPads. It’s known to all that Lightning cables transfer data at USB 2.0 speed, which is 480Mbps/60MBps while USB-C can handle USB 3.0 speed, with transfer speeds as fast as 5Gbps/640MBps (USB 3.1 Gen 1), or 10Gbps (USB 3.1 Gen2), and Thunderbolt 3, the superset of USB-C, is capable of 40Gbps.
That said, if you use any cable and charger under its maximum specification, it should be safe.
A 3A (USB-C) cable has a higher specification on internal resistance than the 2.4A (Lightning) cable. It’s extremely vital to protect USB devices, particularly during fast charging, because it can help stabilize the current and data transfer.Īs the USB-C needs to handle fast charging, it features more protection precautions. The full-featured USB-C cable is required to be packed with an E-Marker chip which runs CC (Configuration Channel) to identify and monitor data between USB devices, thus controlling the power supply. Does the chip actually make the cable safer? Yes, if you compared it with a non-MFi Lightning cable but, no, it doesn’t necessarily mean it’s more reliable than a USB-C cable. Its purpose, according to Apple is to ensure the safety and quality of the cable, which is a basic security requirement for any cable, and guarantee compatibility between the accessories and the Apple devices. The chip used in the Lightning cable is used by Apple only.
