The Lindy 4 Port USB 3.0 Hub with 3 Quick Charge 3.0 ports provides convenient access for up to 4 USB peripherals and storage devices. Capable of data transfer speeds up to 5Gbps, the hub is also backwards compatible with USB 2.0 and 1.1. The 3 dedicated QC 3.0 USB ports guarantee fast and smart charging of USB devices like smartphones or tablets (both device and charger must support QC). Connected devices are automatically detected and optimally charged with max. 5V and 2.4A per port. Batteries in devices are faster charged than standard USB allows by increasing the supplied output voltage, while adopting techniques to prevent the battery damage caused by uncontrolled fast charging and regulating the incoming voltage internally. The hubs individual On/Off switching ports can help reduce overall power consumption and are perfect for accessing external hard drives or other periodically used devices. The included 54 Watt power supply ensures that there is always enough power available. Each port has its own LED power status display.
