Ideal for a Raspberry Pi,
Verified Purchase(What is this?)
This review is from: AmazonBasics 7-Port USB 2.0 Hub with UK Plug (Accessory)
NOTE: THIS REVIEW APPLIES ONLY TO THE 7-PORT USB 2.0 PRODUCT WITH TWO HIGH-CURRENT OUTPUTS. OTHER PRODUCTS SHOWN HERE WILL BEHAVE DIFFERENTLY.
Rather than having a power supply for my Raspberry Pi and another power supply for a hub, I wanted to power the Pi from the hub. The trouble is that most hubs will only supply 500mA per port, which is not really enough for a Pi. Some hubs tout a higher-current "charging mode" option, but that usually requires the attached device to actively request the extra power. Since the Pi just connects the power terminals and no data, that wont work. This hub is simpler insofar as it just allows a higher current draw of 1.2A from two of the ports.
That means a slightly incestuous arrangement of two cables where the Pi is powered from the hub and also connected to the input of the hub, but it does work well and saves on one mains power adapter. Note this hub does not "back-power" the Pi down the host cable.
The hub itself is rather smaller than I expected (not a bad thing), and the base plate can be attached to the side instead to allow a horizontal mount. That does mean the hub has an ugly lump sticking out of the side when mounted vertically. It is a very light device so, with up to 8 USB cables plus the power cord, it is no way going to stay where you put it unless you stick it down. It can be fiddly to insert cables or devices into the closely-packed sockets, so probably best not plan to use this for anything other than a semi-permanent setup.
I haven't really stressed the capabilities of the hub, but, in addition to the Pi power, I have had 4 real devices attached, including an external HDD also powered from this hub, and it behaves perfectly.
I was impressed with Amazon's "frustration free" packaging, being easy to open and made almost entirely of recyclable card.
Overall I like the functionality and would buy another one, but I would have preferred a simpler shape without the stand and a more accessible layout of sockets given, judging from it's weight, it must have mostly empty space inside it.

Ah. Thanks for the review in regards to the Pi, helped a lot.

My version of this product (which as advertised is a 7port USB3 Hub - not 2.0), it is not possible to use with a pi, as no power is available unless the input USB is connected to an active computer (i.e. a computer that is switched on and has the hub connected into the input USB port next to the power supply input).
As the pi is not active until powered, the hub never "switches on" to power the pi! So I would say this product is useless for those wanting to run a pi and related peripherals.

At the time this review was written the USB3.0 version of the product did not exist. The review is of the USB2.0 7-port product as it has the two high current ports. It is a shame Amazon bundles all the reviews of different products together causing confusion like this. I have submitted an edit of my review to emphasize that the discussion only applies to one of the products on this page.
