Connecting two monitors to MacBook Pro 2017 while charging it I am using a 13" MacBook Pro 2017 with a Shinevi Hyperdrive adapter for access to a wider variety of ports, granting my access to a single Thunderbolt 3 port, a USB Type-C port, and a single HDMI port.

While fully charged, I can connect both of my Samsung S22C300 monitors with no problem, one through the HDMI port, and the other through the Thunderbolt 3 port. (Note: The single Thunderbolt 3 port is the only port that allows you to charge the MacBook through the Shinevi hyperdrive). This configuration allows me to use 3 screens in total, including the MacBook Pro screen.

However, when my laptop starts running low on battery, I have to unplug the external monitor connected to the Thunderbolt 3 port in order to charge my laptop, leaving me with only one external monitor.

I'd recently bought an HDMI splitter (I have no idea what model splitter it is) in hopes of connecting both monitors through the splitter, but neither monitor is receiving signal through the splitter. I have also checked to see if the splitter is broken by testing it on other devices, and it works elsewhere. 

can I charge and have HDMI out from one thunderbolt port?
One solution for the problem here is to use a Apple USB-C Digital AV Multiport Adapter. It is available on Apple Retail Stores and Apple Online Store for $69.00.
