FAQ
Does this USB hub charge a connected devices?
No. The JoyReken USB 2.0 4-Port Hub is not intended for charging any mobile or other devices. Both ports on the 4-port hub share the available power from the one upstream port (at maximum 900mA shared). It is intended for low or self-powered devices and is not suitable for charging.
Is this compatible with my car audio system?
No. Car audio systems do not support USB hubs.
Can I connect two USB bus-powered external hard drives without external power supply?
No. One or both external hard drives will drop off the USB bus since this USB hub splits 900mA at best between four USB ports.
