Durable Aluminum Casing REMINDER: Compared to the plastic case, the aluminum case has better thermal dissipation which means heat that occurred inside would be conducted to outside more quickly, making this adapter safer but a bit warmer (which is normal) than the plastic case. USB C to HDMI VGA Adapter HDMI port provides a simple plug-and-play connection to a second display or monitor at a resolution of up to 3840x2160@30Hz. For 4K resolution, please keep an extra HDMI cable within 5 meters. VGA port provides MAX 1920x1080@60Hz 1080P video output. Important Notes USB C PD fast charging is only for laptops but not for phones. Phones only support normal charging. Do NOT recommend you charge the phone through the USB 3.0 port as the USB port can only offer max 1.5A current and will charge your phone slowly. Do NOT use 2 hard drives simultaneously or a lot of power-hungry devices through the USB 3.0 port since it cannot provide enough power. NOTE: HDMI and VGA ports can NOT be used or connected at the same time. NOTE: We do not suggest you use this USB C hub with any other USB C smartphones, since some ports such as Ethernet, card reader, or USB C PD charging port may not work.
