Charge 2017 13" Macbook air through Thunderbolt 2 port, while connecting display

I currently have a 2017, 13" Macbook Air, and have been looking to buy a monitor to have at home. Is there a product that would allow me to power my computer, while connecting an external monitor (preferably HDMI), through the Thunderbolt 2 port?

No, unfortunately not. As stated in the comment, TB2 does not support power delivery. If you were to find an old Apple 27" Thunderbolt Display it comes with a cable that has both a TB2 connector and a Magsafe 2 connector, which can both deliver display signal from the laptop to the monitor AND power from the monitor to the laptop. https://en.wikipedia.org/wiki/Apple_Thunderbolt_Display I don't think there's a 3:rd party monitor that has that available unfortunately.
