Renkforce 4+1 PORT USB 3.0 CHARGING-HUB 1268677 Manuale Utente

The USB power output on the side of the USB3.0 hub supplies a current of up to 2.4 A. 

Hence, not only smartphones can be connected here (they usually require a charging 

current between 0.5 and 1 A) but also tablets with a higher current requirement (e.g. 

iPad).
Use the USB charging cable provided with your smartphone or tablet to connect it to 

the USB power output.
Since the charging electronics are integrated in the smartphone or tablet, the charging 

process is controlled and completed by the smartphone or tablet. 

•  The USB2.0 hub is USB2.0 and USB1.1 compatible. This means that normal USB2.0 

and USB1.1 devices can be used without any problem on the USB3.0 hub. However, 

this will not speed up the USB2.0/USB1.1 devices.

•  In order to take advantage of the high speed provided by USB3.0, all the devices 

must support USB3.0: The USB device itself (e.g. an external hard disk), the USB hub 

and the USB controller in the computer.

•  The theoretical maximum speed for USB3.0 (or also USB2.0 or USB1.1) is never 

achieved in practice. This is due to protocol information, simultaneous operation 

of several USB devices or the speed limit of the connected device or the USB 

controllers/motherboards.

  It also makes little sense to simultaneously operate 4 hard drives via the USB3.0 hub, 

as these share the possible volume of data transmission between the USB3.0 hub 

and computer. 

  If, for example, a lot of data is to be transferred between two USB3.0 hard drives, 

connect the first hard drive to the USB3.0 port on the USB3.0 hub and connect the

second directly to a USB3.0 port on the computer. 

•  Normally USB operation is not possible in DOS or in the protected mode of older 

Windows versions. Depending on the computer or the BIOS/Setup, however, 

operation of a USB keyboard and a USB mouse is possible. Nevertheless, it is 

necessary to connect them directly to the computer’s USB interface and not to the 

USB hub. 

•  USB devices can be connected and disconnected during operation. You do not have 

to switch off your computer if you want to insert or remove devices.

  If data transfers are in progress on the USB port, e.g., if an external disk is inputting 

data into the computer, and you unplug the USB plug, the operating system might 

crash. Furthermore, loss of data or damage to the file system of the external drive

can be the result.

•  With Windows

®

 XP, Vista™, 7, 8, an icon with an arrow in the menu bar is displayed 

for some USB devices (e.g. for a USB hard disk). With this function you can 

“disconnect” the USB device from the computer so that no data transfer occurs any 

longer. Afterwards, the USB device can be disconnected from the USB3.0 hub (or 

the computer) without problems.

Remove the product from the power supply before cleaning.
