Transcend HUB3 4-port USB Hub - USB3.0 - with power supply

This little gem does exactly what I was looking for i.e. allowing me to plug in multiple external drives (3) which require power. It works perfectly with all my drives recognising them immediately. I haven't tested for transfer speed, but that's not an issue for me: I usually transfer large volumes of data and just leave the computer to get on with it.Can't really comment on the fast charger port as this is of no interest to me.As with some other reviewers I received the unit with EU power supply. I went online to arrange for a replacement and received new UK version the next morning, Kudos to Amazon for this speedy service which I have had occasion to use in the past.For me it's five stars because it does exactly what I wanted.

Excellent product, performs as expected, however dropped a star as mine did not come with a UK power supply as stated in the product description. What came was a EUROPEAN (SCHUKO) style plug that requires an adapter for use in the UK. frustratingly the "plug" portion is removable so the UK section could have been included.

An excellent powered USB 3 hub. I use it with an ASUS tablet Win 8.1 computer. See my uploaded images.As shown the main use is when traveling to backing up photos/videos from the USB3 card reader to the 1 TB disc.Note that the tablet PC does NOT charge via its USB3 connector in the keyboard half, but rather via a power-only micro-USB in the display half. Hence a cable from the hub power-out socket to it. So the only mains brick I need is the one for the hub.

This is a nice looking and compact USB hub that feels well made. Had it about a month and is connected to a Porsche Hard Drive, DVD Re-writer plus USB flsh drive and MP3 player (file transfer & re-charging) works well and does the job intended. The hub was also relatively inexpensive. Job done!

This works OK some of the time.I wanted this because I have a media player and, brilliant though it is, it was unable to power an external SSD via USB. After buying this powered hub I found that it was able to work. With just one SSD plugged in. It seemed unable to handle two SSD plugged into the ports. The power supply is always attached. An UK three pin supply was supplied. I really wanted to be able to keep those two SSDs attached all the time. They do not actually draw much current but too much for the hub.I have downgraded it to a USB charger as the charging USB port works OK with my Kindle and Samsung Note phone and Drift Ghost HD head-cam.UpdateI have dropped my rating from three to one star now. The performance has deteriorated such that it can no longer power one drive. The smaller of the SSDs can be driven without the hub. The larger will not work at all. Therefore, I am in the same position as if I didn't have the hub. I am becoming more and more frustrated with buying simple electronic devices that should just work, and then don't. Manufacturers should beef up the components in their products so that they can cope with the maximum that could be asked of them rather than the minimum.

I've just opened the box to find a two-pin PSU has been supplied and not a UK three pin plug. Why would they include this PSU when selling to UK residents? That's just lazy and annoying, I now have to either source an adaptor or go through the hassle of returning the item.It will be interesting to see what the retailer has to say about this as I notice several other people have left reviews stating they've received the two-pin PSU too, you'd think they'd get it right.

The Raspberry Pi requires a maximum of around 750 mA to be supplied via a micro USB port. (There is a 'polyfuse' of 750 mA).The Raspberry Pi also has USB2 port for data communications.The power that can be supplied by the Raspberry via its USB2 ports is limited. Insufficient to power USB drives and, probably, WiFi adapters. Hence the need for a powered USB hub.I had planned to supply power via the TS-HUB3K "dedicated fast charging port" and use the other 3 ports for communications.This will not work and Transcend have offered no solution.The problem is that the Raspberry Pi boots when power is supplied, however shortly later the Raspberry activates it's USB2 ports and thus the hub's 'upstream' port. The hub reacts by momentarily interrupting the power supply. This causes the Raspberry Pi to reboot and the sequence loops. The power supply LED on the Raspberry flashes (about once a second).However, there is a way around this problem. But this means that power cannot be supplied via the 'dedicated fast charging port'.The solution is to power the Raspberry via one of the other hub's ports - NOT the 'dedicated fast charging port'The USB3 standard says that a USB3 port can supply up to 900 mA (USB2 is 500 mA). If (this has not be confirmed) the Transcend port does this then this should be sufficient to supply the 750 mA needed. It might be the hub sees an 'upstream' port of USB2 not 3 and therefore limits to 500 ma.In practice I have successfully run a Raspberry in this way with an external USB disk and WiFi adapter.Also to get more power from the 'dedicated fast charging port' requires special drivers that are only available on Windows or OS/xi.e. not the the Raspberry Pi Atom.Finally it may need care on what devices are supported via the 'dedicated fast charging port' - they would need to tolerate a power interruption early in the boot process. WiFi OK?, hard disk used soon after boot?In summary, I would say that I am happy with the port for use with a Raspberry Pi but that there are some limitations that had to be investigated at some considerable investment in time.

Well made works fine very pleased USB 3.0 hubs are still thin on the ground this is good value. However the cable supplied to connect the PC to the hub is very short (approx 300mm) you can of course add an extension cable which I have done that aside great hub very pleased.
