I rate this a 4-port USB of HooToo with OTG function that kindly of ZBT Trading was provided.
The device itself is nice handy that material is made of plastic, although it aberf looks valuable and works through and through sound. With 4 USB ports (two of them with variable voltage) can be loaded simultaneously to four devices. I myself have been two tablets and two smartphones for a total of four devices can load without problems simultaneously. Of course you can load its devices with proprietary chargers, but sometimes five devices need to be charged at once when times four or then acting partly already very chaotic and messy. So you can see the device anywhere and banish all load simultaneously (women feel good factor *****).
On top I find the OTG function (on the go), very good indeed solved just once to connect a USB stick and filling the smartphone with fresh music, is sometimes done up in no time.
The item comes with a power cable and the associated OTG cable.
The manual is indeed a joke, but the part itself is simple to use and ingenious in its simplicity.
From me it gets a clear recommendation.
