I have an external hard drive, a keyboard slot, a super fast mouse, a drawing pad and a microphone. I trade and use everything at the same time with heavy applications. I was worried it would be too weak to make them all run fast, but it works great! Never disconnects or connection issues and 0 lags. I'll get a second one that connects 2 USB items for my less needed extras. Additional Info: All my devices are USB-A or USB-C and they all work very well with a single Lightning connector.
