Help with building a 12v battery box.

I am interested in building a portable battery box with USB sockets and a light attachment. I understand how to build one and how to wire the circuits, I'm just confused as how I'm meant to actually charge the battery after. Do I just wire a positive and negative to the battery and then into a 12v socket on the case and then with a battery charger wire it on to a 12v plug? Thanks.
