5 of 5 Excellent charger! August 6, 2022
Reviewer: Anonymous Person from YYPA United States  
I have 4-5 different chargers to charge the 4-5 different batteries I need to charge. Now I can charge all of them with this 1 charger, When I received it, I immediately placed 4 different batteries in the Ci4. It worked perfectly.
