We use the Conector at 2 Samsung Galaxy S4 devices. The back and herstecken works fine, as does the connecting a Bluetooth keyboard. This could be sure, are infected as USB, but the keyboard via Bluetooth was just earlier in the House and will continue to be used. With 3 USB ports (USB 2.0 Type A) in any case sufficient space is offered, also for a memory stick.
In addition, he has 4 card slots for the card formats TF (T-Flash), SD, SDHC, Memory Stick or Memory Stick 2. So the phone within seconds the notebook is equally worthy and gives the user new applications and possibilities.
The connector is compatible with the Samsung Galaxy S3 / S4 or the Samsung Galaxy Note. 2
You can also connect an external hard drive via an additional power supply, so you can tilt not only large amounts of data but also easy time watching a video. The need for the power supply adapter to the USB connector is not supplied, the connector itself, however. When working with a mouse and keyboard and / or drive the extra power is not needed.
The connectors are accurately fitting, everything can be easily interconnected. If the connector successfully connected to the mobile phone, this is signaled by a blue LED light.
For me, an accessory which I absolutely happy to recommend.
