will this power a 7 port hub with all 7 ports being used by 7 different 16gb flash drives , im trying to avoid buying an inverter for powered usb hub

if you need a USB to M Barrel cable, and you have a power source that has 5 volts at the right current this will work, other than having the right ends on the cable, You will need a power source to plug one end of the cable into, an a 7 port hub that takes the other end of the cable. most hubs hook to a USB port on a PC or laptop to a usb out on the hub, usually a USB2 to a USB2 cable if external.

You can use it to regulate your 12v from your car to 5v. It is not specifically designed to power a usb hub....

You know what thats interesting that you bring that up. I hooked a 4 drive enclosure to this hub and evey time I would write to the drives on in the enclosure they would drop off (meaning they would disconnect and then re-connect). when I connect the enclosure to the 3.0 port on my actual machine it worked? I wonder if its becuase of what you brought up with the current not being strong enough? But I dont use this thing. The power connector is flimsy and the ports sometimes would not power up at times. its not well made I would not recommend buying this.

In theory, no. Not according to the USB spec. If you run 7 USB 3.0 devices, and they all draw 900mA, then they will request 31W and only receive 20. In reality... very few devices will draw that much power... but know your devices or do the math

Hi there Since I have the 4 port USB3.0 ...I have checked that my external hard drives that are powered up by an extension cord are USB2.0 and it works with my USB3.0 port on the USB HUB. I can not see why not it would not work with the 7 USB 3.0 port. I have this USB 3.0 port hub on Windows 7 Ultimate so it will work with windows 7.

I know this isn't answering you question, but I don't know. I don't even use mine anymore because it wasn't so great. I recommend getting a Belkin USB hub.

If your box appears as a single drive,maybe. be aware that this adapter will change the format of your drive and although you can still read it, it might not work in your situation. The manual not too clearly states that it doesn't work with USB hubs, and if your drive enclosure treats the two drives in that way, it won't work. Back everything up first, and be prepared to reformat your disks if it doesn't work.

The hub will NOT work with out power. I tried it out with one USB drive and it will not read the drive until AC is added to the unit.

When I tried to pull that much current through this hub... it shorted out, and destroyed every usb peripheral that was attached to it. I believe by the power ratings it might work... but i wouldnt risk it.

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.

It well work but at USB 2.0 speeds. I checked mine, when I plugged it into a USB 2.0 port, Win7 loaded a generic USB 2 driver and it appeared in explorer. When you upgrade to a USB 3 capability it well need it's 3.0 driver installed.This is a good hub, it has it's own power supply. I use it to power Raspberry pi's.

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.

Sorry I really don't know. USB devices like this can be plugged into many ports, but I don't know about chaining them.

This hub does not include its own power supply so the *total* current it can supply among all four of its ports is the maximum the port it is plugged into can supply. For USB 3 ports on desktop computers, that is usually 900 ma (0.9 amps); for some laptops it may be only 150 ma (0.15 amps). So no, it will not supply anything even close to four amps on any of its ports, nor will it supply more than 0.9 amps on any one port when plugged into a normal USB 3 host port on a computer even if the other three of its ports are unused.

It needs 2 powered USB ports to operated correctly. You would need would need 2 hubs

USB ports can only supply limited DC power. Sometimes a two or three port passive (no power supply) USB hub can be useful, but don't expect a seven port hub to operate without a separate power supply. If you're inventive, you can construct a battery power supply with parts from Radio Shack so that you can occasionally operate away from utility power.

In general you can charge USB devices on a powered hub with out a computer. I do it with my FitBit, cellphone and my son's 3DXL. As far as this hub is concerned, it under powered. Their 10 port has more power and USB 3.I bought the 12 found it not capable to power 6 devices at 2.5 watts and reviewed them with my experience. They responded to tell me in my needs I should use their 10 port and return the 12. I have done that and the 10 port is doing the job.
