I bought a combo so that I had 3 batteries, but it wasnโt there. One charged, the other with grief in half from the fourth time, and the third is completely dead. Neither from a single block, nor from a triple one, does it charge anything and does not show any signs of life. The stupid amazon chat says to issue a refund, I donโt understand why I canโt contact the store and replace only one battery. I'm leaving, I have no time to deal with the return. For that kind of money you get a damaged product, and even the problem cannot be solved. Never again will I deal with such serious purchases on the market. Just disgusting
