Ugreen USB 2.0 Hub 4 Ports with OTG for Smartphones Tablets

I bought this to connect a portable HDD to my OTG capable android tablet. It works.If you plug in the hub to the tablet and then connect the HDD to the hub, it will not work. You have to connect the HDD to the hub, supply power to the hub, and then connect the hub to the tablet. It'll work fine if you do it in that order. Maybe this issue is universal or maybe it's just a problem with my device.All the ports are working fine simultaneously. I have a mouse, usb drive, and an HDD connected all at once.The design of the product is quite nice but the material it is built with feels pretty cheap. The cable that connects to the host device is good and I have no complaints there.EDIT: Okay it was probably just a problem on my tablet. I don't have to follow the procedure I was talking about earlier anymore. I also want to add that the ports on this thing is very very stable. Touching the hub, moving it around, adding or removing devices from the hub, does not interrupt file transfers.

Good

USB ports works fine but the mobile charging does not work.

This wasn't a great fit for my Fire TV Stick. It didn't aid anything but power supply from my TV to Fire Stick TV. Probably has dependency on the android TV version in recognizing the attached hardware. However, pretty useful as extender on my computer.

Hey First of All This is not a charger it's multiple otg connector For Android Smartphones working well as expected It can connect External Hard disk pendrives without using your smartphone juice if you're near to the wall power socket then connect it with it otherwise use your power bank and you can use otg device without draining your Smartphones.. working as expected quality product Highly recommended!!!

This Product is totally Value for Money and i like this product and using it without any issue or lack.

its female mini otg port on the body near roundal USBs is not at all working. Neither it connects even keyboard with mini OTG port, nor it is working for charging the tab (i think charging is not possible here). its only useful for tablets with mini OTG connection and can use with USB ports for mouse, keyboard(with standard USB port connecter), and one pen drive at a time. but if u want to charge the tablet with body female otg port you can't do. the use of this female OTG port on roundal body is not worth.totally its a waste item. U green cheated and also amazon.....

Build quality is excellent. No issues with connecting any device or connector (for which this product is made).The connectivity and ease of data transmission it provides is unmatched due to the combination of USB sockets and upgraded technologies included here (e.g. OTG).Go ahead with it worry free if you tend to backup data between multiple kind of devices like mobile phones, computers, pen drives etc and like to use accessories such as mouse etc. on your mobile phones, tablets etc.
