Can this be used to boost power for a wd 2tb external hard drive

Don't know. All this thing does is provide the power of two USB ports rather than one USB port to the same device. Is that adequate? The size of the drive should not matter, whether 500 GB, 1 or 2 TB--it is just surface area; RPM may be a factor. since more power maybe required to spin faster. I got mine for the 7,200 RPM drives--recommended for such--but ended up not using it and using the external power adapter instead. I have not used my Y-splitter to date--should return or resell it. WD also makes an external power adapter for its drives--I have one for its backup drive. The Apricorn external power adapter is $10, cheaper than this. Idea is this may be more flexible.

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

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.

this unit powers from usb on your computer.it ties up two usb ports.if you have a separate cable and i independent that you can plug a cable into to power the drive.it would work.but you still have to use the computer.the sad part is you can only use a 1tb drive in it.a 2tb drive will not fit.take care.

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.

I assume you plugged it into USB 3.0, right? Most USB 2.0 ports will not provide enough current to power an external HDD.

I have a Toshiba 1TB and no external power added in the USB port. Yes it works.But I would suggest an external power supply for the Hard Drive. This Device is a dreamwith all its different function. Its does all that stuff it claims... Charges Device (Phones and such)...its own wifi hot spot and wifi extender... Media Player thur USB flash and SD card... Excellent Buy... I have 3 of them

Yes you should be able too. I will warn you that you still need to have power to the HDD as well as the small four pin power connector on the adapter.

Yes, but you have to plug into 110 volt outlet. A WD USB powered drive is what I use for this purpose. They are compact and new models are over 1T.

Like it's been said if your drive has a plug you should be fine, but the longer a USB cable is, the less amount of power there is that GETS to a device. Like the rep said I doubt this would charge / power ANYTHING, not even a tiny mp3 player. Let alone a usb hard drive like a WD passport.

Yes, provided you use your laptop near an AC outlet; the external drive has its own wall-wart power supply. If you want an external drive that's as portable as your laptop, look at the many small portable hard drives that are designed to draw power from the laptop's USB port -- or in some cases, two USB ports for full-speed performance.

If you use it for 2.5" drives then you don't need external power supply. You do need external power supply when you use it for 3.5" drives or DVD/Bluray drive.

I currently have a 1tb usb drive connected and it works great. I don't see why it wouldn't support 2tb.

You need the 2 ports to power the HDD. Depends on your hard drive model only one port may not be enough.

Yes. I have connected multiple external hard drives to this hub. It is a powered hub and will power drives that are not externally powered themselves (Drives which have only a USB connector and no DC adapter input).

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

all you need is a 12vDC 2amp power supply. i would take the drive with you to make sure the plug fits it
