Powering the Viltrox DC-550 PRO
When it comes to power management, there are three ways to supply power to the monitor:
USB-C power delivery via a 5V 3A power bank or USB power brick
NP-F battery pack mounted on the battery plate at the back of the monitor
DC-IN 12-18V barell connector

The monitor has a useful clip-on pop-up sunshade hood which can help when filming in bright environments and also acts as screen protection when folded. The whole monitor weighs 280g and its dimensions are 165 x 91 x 28.5mm. There are vents on the monitor, so it has active cooling.

Viltrox includes a rich set of accessories with the monitor. On top of the monitor with the sunshade hood, there is a cold-shoe swivel mount, HDMI and USB-C cables, a storage box, and even one NP-F550 battery included in the box.
