USB-C (using the USB 3.1 protocol) to HDMI 1.4, USB 3.0 (downwards compatible to USB 2.0) and USB-C (Power Delivery) adapter for connecting and transfering audio/video signal, data and power from the MacBook 12″ with USB-C port.
The HDMI port supports HDMI 1.4 and resolutions up to 1080p and even UHD 4K to be displayed on an external display, projector or TV while transfering the audio signal in digital multi-channel quality. Through USB 3.0, data can be transferred at up to 5 Gbps. The USB-C port allows to supply the connected devices such as an external USB HDD with power while charging the MacBook 12″ at the same time (Power Delivery).
Important Notice: Unplugging the power delivery (PD) from an external power adapter via the LMP USB-C Multiport Adapter can cause the sudden interruption of the power supplied to attached devices (i.e. an external USB HDD). This in return causes attached devices to be unmounted or to loose the connection shortly (the connection is re-established automatically after 2-3 seconds) which may bring about a loss of unsaved data. Therefore, we strongly advise to save all data and/or unmount any attached device before unplugging the PD!
