Latitude 3420 USB-C charging

Hello. I am new to a Latitude 3420 and wanted to know if it is possible to charge it through its USB-C port using a portable charger (car or cell phone). The USB-C port on the laptop only has a Data symbol, it does not show the Thunderbolt icon.

I have 30W chargers for car (Anker) and cell phone (Moto), I don't know if they will be enough or which one would be correct.

I don't know if I could damage the laptop by trying these chargers.
