Is this device suitable for most external hard drives? (The kind that require AC power, not the ones that can be powered solely off of the USB plug.)

This is a 9volt DC power supply, rated at 1.5 amps. As long as know that the power requirements of the external hard drive are less than 1.5 amps, it should work. You have to match the plug and polarity to use it. This is very important. Incidentally cable is 5 foot long.

I have not used it for such, only using it with a Raspberry Pi which has limited power capabilities from its USB ports. Check the documentation but I believe the total power limit for this device is around 2 amps, so you need to determine the power requirements of the drives. Further, there are only four ports on the device so without further extenders (it's frequently a bad idea to add USB extenders onto to USB extenders, I've heard stories of problems) you're limited to four devices. I do believe there are 8 port powered USB extenders available as well. You might want to investigate one of those. But first determine the total power requirement of your drives.

For me I found external hard disks worked, but I would get short term disconnects. I replaced my hub with a Anker hub and haven't looked back:https://www.amazon.com/gp/product/B00GSLMTQ8/ref=oh_aui_search_detailpage?ie=UTF8&psc;=1

A 2.5" HDD -laptop hard drive- or a SSD hard drive will work fine as I am using this on a daily basis. All these being said, there a very slight chance that your USB port won't have enough power to sustain my claim. But, given that there are 99.9% chances to work fine, what have you got to loose? It WILL WORK with either a 2.5" HDD or a SSD drive. I used with four devices at once without the need for external power. The UNTEK hub DOES COME with an external power adapter.

you're wrong this device is used to connect an internal hard drive as an external hard drive via usb, but in my case it did not work.

In order to get this unit to work with my hard drive I had to use an external power supply so i would have to think that you would be better off with a direct connection to the computer for charging any device. Hope this helps.

Yes, I am successfully using this with all my USB 3.0 External Hard Drives 2 1/2" (Seagate's and Toshiba's) ranging from 500 GB to 1 TB. Works like a champ. I am using this on a Windows 7 Home tower computer I built (Intel platform). This unit provides enough power to run the external hard drives at USB spec 3.0.

Nope. You need to use the included power supply. The USB port simply does not deliver enough power to operate 3.5" based external hard drives. Thumb drives use flash memory and the portable hard drives use smaller 2.5" or 1.8" laptop hard drives which use less power.

Do the external drives to be connected to the hub have their own power source? If they are intended to run off of the power of the hub, you may have problems. This is my speculation based on the note under the product description stating the product should not be used with WD passport hard drives. I have several of those, each 1TB, and they run off the power of the hub. Currently, they are plugged into USB 2.0 ports, but they are USB 3.0 compatible products used as "backwards compatible," and run very slowly with USB 2.0, but they run. With USB 3.0, there is evidently a reason they are not supposed to be used. So, I would say it depends on whether the external hard drives have their own power source and, specifically, if they are WD passport drives, the product information I saw said they should not be used with this hub.

Ron....no, the hard drive is a plug-n-play, no external power source needed.

Yes, I have had similar issues with other external, enclosed USB hard drives. That is, they get VERY hot, and then shut down after about 30 minutes of operation. These enclosed drives are pretty much useless unless they have a vent and cooling fan. I really don't know how anyone uses them successfully. The only way I have been able to use them is to keep them completely open, which means removing all the casing and just laying the bare drive and it's connenctors out in open. Pretty ugly, but it will run all day like this :-)

It does not work with a Seagate 1.5TB thick portable drive, keeps disconnecting when read/write to it. When connecting a small drive like WD 1TB, 80% of the time will be fine, but it disconnects as well. No matter what power adapter you use! I even tried to use a powered USB hub. It can read and recognize external drives connecting to a USB hub, but it will disconnect from time to time with no apparent reason.

this power supply *should* work with most devices requiring 5v power (such as usb hubs and external hard drives) and that have a 5v power receptacle that mates with the plug. however, you might want to watch the voltage as some units seem to have unstable voltage levels (one reviewer measured 6v from his unit) and i measured about 5.3v from mine, which seems a little high to me. any more than 5.1v and i'd be wary.

Not sure. Seems like that would work but I've had experience with other USB extensions that can't handle large peripheries like external hard drives.

No. This device does not need external power. Direct plug and play ( like a thumb drive)

Any external USB hard drive can be used via the USB ports, the seagate HD is necessary to for the "convenient" slide in interface (it still leaves both USB ports open)
