I have external drives from transcend that do not have an external power source. Will this hub be able to power one of them? Both?

I use a WD portable drive and it works well with this USB hub. (I did not try with more than one external drives.)

The answer is yes; 4 different peripherals can be connected to be powered from 1 usb hub of a pc. With multi connections case; in order not to lose any data transfer speeds of the connected devices, usb hubs of the pc should either be usb2.0 high-speed type or -much better- usb3.0.

It depends on how many drives you will use simultaneously. If it is only one or even two, you will have no problem powering them. However if you will use more than two drives, you should consider buying an externally powered USB hub.

i plug in a couple of external drives w/out power source all the time. works just fine. don't know if it'll power more than 2.

No. The Transcend drives are very model specific. Go to their website to see model compatibility. See the answer from Cai Li.

The Belkin SuperSpeed USB hub will not provide power to the host computer nor draw power from computer battery. It has its own separate battery adapter.

MANUFACTURER ANSWER: Thanks for asking! You can connect two self powered external hard drives to this hub. This hub will not be able to power two host powered external hard drives. USB 2.0 has limited performance overall, however, you should not see any noticeable drop when comparing this hub to using several USB 2.0 ports directly on your computer.

yes, but but external drives suck up too much power for most hubs, like this one. Mouse, keyboard work fine, so try to connect external drives directly to computer.

No. It requires external power for the drives and most other USB-powered devices. I ended up connecting my non-powered USB devices into the hub and those requiring power directly into my iMac. Fortunately, I had sufficient devices that didn't need power that it worked.

If you are using the power adapter that is supplied with the USB hub the hub then is independently powered and the external drives are more than likely being "tricked" into thinking that there is still an active connection between the drives and the PC, therefore the drives will not turn off with the PC. If you unplug the adapter the external drives should then shut down also. Will the drives being on damage the drives? Not really, because there is no actual activity (reading/writing) taking place when the PC is turned off. Does it use a little electricity? Yes, but it would be minimal. Bottom line, if you are concerned about the drives being left on, unplug the power to the hub and they should shut down. If it means anything, I have a PC that I built with 5 Western Digital Black Series 4tb hard drives in RAID 0 and a 2tb external WD My Book attached that run 24 hours a day, 7 days a week and they are fine.

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

Yes, a device like this would cause a powered external drive to stay on as long as the USB hub is powered.

Not sure, depends on your source USB port. To be sure, I would purchase a "powered" USB hub to connect your drives.

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

I haven't personally tried this, but it is externally powered by an outlet, so I don't see why not. It would have enough power to work. But speeds will depend on your computers chipset, your external drives and the Hubs maximum supported rate.

I haven't tried the first scenario. I am running 2 external USB drives with their own power supplies.

The hub has one high output power port on the side, that uses the AC adapter. The other 3 ports seem to run power through the main line without the AC adapter. How much power are you going to need to run you Hard drive, I don't know. I do know that my iPad only will charge with the power plugged in and it hooked into the high output port.

I think you would be better served with a power adapter hub... search "usb hub with power adapter" on Amazon. I wouldn't put a HD on this Sabrent USB 4port Hub 2.0, it seems to lose connections with HDs too easily.

Dear Annabelle, Unfortunately, our Premium 4 Port USB Hub is not powered, and will not power an external Superdrive (which is the case with most USB hubs) as they require over 500mA. The total amount of power going to the hub may not exceed 500mA. If you have any other questions or concerns please let us know. Thank you,Satechi Technical Support

no. the device needs to have power to work. The largest external hard drive i have seen that can be powered by thunderbolt alone is 2TB
