Does this produce enough power to handle an external hard drive with a Raspberry Pi?

I am sorry, I don't know. I just use to hook my mouse and a small USB thumb drive. It doesn't work when I hook the printer to it.

It uses a single USB plug to power even a 1TB laptop hard drive externally. No extra power needed.

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

Each USB output port can easily handle a USB 3 current load ( which is Greater than USB2 Current load. If your External Drive strictly operates from the USB3( or USB2) data cable that also carries power, it should be able to deliver and operate it. No harm will be done try it. ( Note many External large hard drives also require a separate external DC power connection. Check and refer to your Hard drive manual for it's specification and connections. Good Luck. BobNaz

I have 3 Hard Drives plugged in and drawing amperage with no noticeable shift in power. I plug in my phone and my ipad to the same unit and they are both happy with that. I have to guess the outputs are regulated and adequate 1/2 an amp isn't a big draw!

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.

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.

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

i believe yes ,i connected a digital radiography sensor and worked with no problem, so it can handle an external drive easily

Sorry, I have no idea. All I've ever used them (several) for is to provide power for USB devices connected to Raspberry Pi's as the Pi's USB ports are rather anemic power-wise.

I doubt it would work at all, it does not have the four pin slots to power the hard drive, but for the price, and if you're courageous enough to, it wouldn't hurt to try.

The hub has a 12 volt, 2 amp power supply. I assume the amp capacity is divided among the 4 ports. You'd need to find out what the current draw is of the external drive to be sure.

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.

I have two that are self powered with no problems. In my opinion it should support 4 external hard drives because it plugs into a power source.

Yes. It will power up to a 1.5TB NTFS drive. Hope this helps. Have a great day.

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.

No, I draws its power from the mother board. You may be thinking of USB hubs, which often require external power. Hope this helps.
