I have 4 pieces with little strings for hanging. They work fine. I'm not an expert on charging speeds because out of habit I always charge when I can. It connects at the same speed it normally connects to indicate charging. The price is fantastic. There were so many options while browsing, so I'm glad I chose this one.
