For a stable connection, the devices connected to the 12 Port hub must not exceed a combined current of 5 volt 2A. Each USB port on our 12 Port hub will only provide 5 volts 250 Milliamps. External hard-drives should be connected to an external power source.
This hub functions as a USB hub only, to connect USB 2.0 and USB 1.0 devices to your computer, and is not a standalone device charger.
This hub is not recommended for ASIC bitcoin miners.

Turns out, I can't even run all 3 of my drives at the same time. In fact running 2 at a time is iffy.
I thought for a while that the power supply might in fact be broken, since it did not seem to run any more disks with the power supply plugged in than being powered from the computer's USB port, but in fact the lights light up and the plugged in devices do see power even when it is not plugged into the computer, so the power supply must be working.
I'm keeping it to run the disks one at a time and be able to access other low powered things, but it is a shame that it is so very low powered...
I would avoid Satechi products on Amazon like the plague. In my opinion, they are manipulating the review system to get rid of anything short of excellent reviews by offering refunds that let you keep the product if you remove your 'negative' review. Previously this was a 3 star review and I got the following email:
We are very sorry for the inconvenience you've experienced with our 12 Port USB Hub. For safety reasons each port has a 5Volt 250mA output and the total amount of power going to the hub may not surpass 2 Amps (to ensure your computer's usb doesn't burn up.) You are most likely exceeding this limit with your external hard drives. Is it possible to connect any of them to an external power source? Also we would like to offer you a refund and you may keep the hub. All we ask in return is the removal of your review. Once (or if) it is removed we will issue your full refund.Read more ›
All works great. I liked it so much I bought a second one for other uses.
Delivery time from Satechi was very prompt.
This did not turn out quite as well as I had hoped. I found that if a total of 2.00 or more amps were pulled by all USB devices combined on the 12 port hub that the hub will shut down. The power supply that is supplied with the hub is rated at 5V 2.4 amps. As I pointed out in my earlier review I changed over to my own 10 amp supply which worked well until I added a 11th USB device that exceeded the 2.00 amps. The specs for the hub make no mention whatsoever of a maximum current rating for the hub but of course the rating of their own power supply (2.4 amps) indicates a maximum current that should be assumed. The purchaser could not know that until their power supply was in hand. I had hoped that the unit did not have current limiting built in but it does. Satechi should revise their specs to indicate that there is a maximum current that can be pulled by the hub. There is no mention of the total current capacity of their power supply or the hub on Amazon or on the Satechi web site.
Long and the short of it is don't exceed 2.00 amps with all USB devices combined on a hub or it will shut down.Read more ›
A USB device needs power to operate. No big surprise there. With a non-powered USB hub, there is 'x' amount of power available to support all of the devices that are plugged into it. This means that if you plug a lot of devices into it and try to use them all at the same time, their performance will decrease because that x amount of power is needing to be divided accordingly.
The beauty of a powered USB hub, is that they are supposed to produce the power needed to support your devices, that way there is no degradation in performance.
Here's the catch for this particular device though. Please keep in mind that this is only my experience, perhaps I was tasking it too hard. From my experience, the "powered" feature of this hub is only for the nifty LED lighting that it has. I plugged in an external drive through this hub and it was dead to the world. Everything that requires only tiny amounts of power (like a USB stick, or a keyboard)are fine, but anything bigger than that, you're not going to be too thrilled with this device.
Don't get me wrong, it looks cool and I like the utilitarianism of the design, but I'm a little upset that they are labeling it as "powered" when it's not actually working by that standard.

Very sketchy. Doesn't seem to pull enough juice to actually support running more than a few of the ports. After that it gets sketchy and things drop in and out. Read morePublished 23 days ago by Slim Jim
