I need an additional USB power adapter for charging batteries. I bought an external charger, but no plug came with it. I need to be able to charge several batteries at one time. I tried calling Fuji but the custom service person said it was available on the website, but I couldnt find it. Any advice https://fujifilm-dsc.com/en/manual/x-t4/first_step/battery_charge/index.html
