Is this iPhone charger original?

I am now looking for a 20W charge

Found two charges. They are second-hand, since the official store does not work. In Ukraine, it is now very difficult to find an original product.

1. The man assures that the charger was included with the phone. I am concerned about the weight, of course the weight can have an error.

2. In this option, the man also says that this charger comes from a set with a tablet.

Sorry for the photo. I have only those that were given to me.

Which version is similar to the original and would you recommend to take?

Thank you very much for your help.
