USB3.1 Magnetic Charging Adapter 40Gbps Data Transfer Speed The USB3.1 magnetic charging adapter, with its 24-pin design, can transfer data at speeds up to 40Gbps (theoretical value). Even files of tens of GB can be transferred in under 30 seconds. Supports 4K 60Hz movie broadcasts and game screens. PD140W Charging Speed Supports PD140W charging speed at 28V/5A. It is also backward compatible with PD140W or less, such as PD100W, 67W, 33W, and 20W. Compatible with Apple MacBooks, iPads, iPhones, and other Type-C (USB-C) devices. For devices that charge using a USB Type-C port, such as smartphones and USB PD (Power Delivery) compatible laptops, the charging cable is plugged and unplugged far more often than when connecting and disconnecting devices to a desktop PC's USB Type-C port. Furthermore, laptops also involve plugging and unplugging external storage devices and other peripherals. USB Type-C connectors are reversible, making them easy to plug and unplug. However, this ease of use leads to more frequent disconnections, and sometimes careless plugging and unplugging. This can cause the connector to become loose when inserted, or the terminals of the cable being inserted can cause small scratches around the terminals. By using this connector, the cable is connected via magnetic force, eliminating the risk of damaging the device's USB Type-C connector and its surroundings.
