Will it also work without being connected to the power supply? for example for a couple usb drives, but having the option to plug in the power for HD

No it doesn't at least from my experience and i'm using a late 2013 macbook pro

It doesn't work without the power being supplied by the plug in transformer.

It probably depends on what you have plugged into it. Note that certain things won't work in this hub - I don't have a single mouse that will work when plugged into it, and mine is connected to the power supply. Call their customer service and I'm sure they'll be happy to assist (although I'm not sure about on a Sunday). Good luck, Claudio. Sorry I couldn't be of more help.

It depends on the enclosure. Some enclosures are capable of powering the drive with just the USB.

Yes, the SATA converter comes with a power supply so it won't work on just the USB interface.

If the drive is a 5400 rpm or solid state then no power adapter required. If its a 7200 rpm or faster, power adapter is required.

Yes it works. However, this item does not come with a DC in port and therefore it will not support high power consumption device such as 3.5" external HDD.

sorry, I haven`t tested that. I will have a USB3 portable hd soon. I'll check it out.

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).

No it functions fine without it BUT if your device requires allot of power like a passport hard drive you will be required to hook up power. Most devices like Flash drives, mice, keyboards, Ect don't

Does the USB 2.0 port provide enough power for the external HDD? Or should I make sure to use an external HDD that has its own power source?

No, without the power connection it doesn't work at all. It goes dark and the items connected are not recognized. I am using it on a Windows 8.1 computer.

There is a AC Adapter included, and since this is built for a 3.5 drive, will require a power adapter, though the nice thing is that it's included.

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

The unit comes with a power adapter but you don't need to use it. I have a ext HD, wireless mouse/ keyboard combo controller and my UPS USB cable hooked up to it without the power adapter plugged in.

While I used it without the power adapter temporarily, I would recommend plugging this in. It will give you better longevity of the device, and it won't use extra power from your computer. I am not entirely sure whether you have external drives is a factor. I assume you are talking about external HDD or DVD drives?

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.

It would be good to confirm that on a few different models of HDD. Many USB ports on players don't provide power for HDD.

Is the power adapter necessary for this drive or will it run off he computer battery if needed?
