Will this cable maintain power from the original port? I want to use a USB hub with this as though the hub was plugged into the port directly.

Genevieve, I would think it would fine as long as the devices on the USB hub don't require much power to operate, but any device that gets its power only from the USB port and has no power supply of its own could suffer, but I just don't know for sure since all I used it for was a printer and the printer has its own power of course. I wish I could give you a definitive answer on the power part, but I'm sure it would work with a USB hub just fine, especially if the hub has a power supply for itself.

Dear Demetre,I am the kind of guy who keeps useful extra items. The darn hub didn't work when it came. I read someone's comment that the power adapter was too small, so I looked in my stash of power packs [some people call them "Wall Warts!"] and found one rated 5V 1Amp. Since then, it has worked, but it's junky - the sockets do not fit smoothly. I notice that everyone else is using 3 - 5 Amps. The item they sent to me was tiny and it was much weaker than my 1 Amp unit.

Yes. However it depends on the device you are plugging in. If the device is BUS powered, then you will need this HUB to be plugged in a power source as it will need to send power to the bus powered device (for example flash drives or USB powered Mics) If the device has its own source of power (like a camera or a powered external hard drive) then you do not need to plug the HUB into a power source and can serve as a pass through.

The manufacturer says this: When the hub's power adapter is not connected, the hub is capable of running purely from bus power (from the host PC). When a hub reports itself as bus powered to the OS, the OS looks in the USB descriptors for every attached device, sees how much power the device reports that it needs reserved for it, and pops up a error (and possibly disables devices) if the total amount of power requested exceeds what a bus-powered hub in theory can count on pulling, which is 500mA for USB 2.0/1.1. We recommend always using the power adapter for best results.

You must always use the power plug for USB hubs. Any product claiming to be a bus powered hub would be violating the USB specifications. There is a specified minimum current for each hub port and a specified maximum current for a bus powered device. A hub must be able to supply the minimum required power to each of its ports simultaneously. If it were to be bus powered, the only source of the power would be from the port that is driving it. The sum of the minimum current for the hub's output ports will exceed the specified maximum device current that the hub would attempt to pull from the driving port.

If you are referring to the USB cable that goes from the hub to the PC the answer is yes. If you are referring to the power supply adapter that is included with the unit it is not permanently attached but it is proprietary and you must use the adapter that comes with the hub. However, you can plug the adapter into a household extension cord and plug that into a power strip or wall outlet in order to achieve the desired extra length.

Greeting from LOFTEK, Thanks for your question. This item is just a usb port charger, not a USB hub. So it doesn't support any data transfers. Thank you.

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 you want only usb cable, yes. It is not AC powered, though. I use one to supplement an AC powered 4-port USB hub.

Nope. The cable serves as a way to draw additional power from diff USB ports, usually used for external hard drives.

I'm using my USB connection to successfully power mine. I have not encountered any issues with this.

I just plug the charging cord directly into my regular USB hub. seems to charge fine. It takes a while to fully charge the first time.

To answer your question yes is port supplies the 2 amps. Each USB port is dedicated. Unlike a hub that would split power. I had two iPads connect as well as one iPad and one iPhone and it worked perfectly

Its here on my desk top right now, thus it is easy to verify your question. NO, the unit immediately went off line and disconnected. Upon application of the power it came back on line. I selected this unit for two reasons:USB 3.0 and the higher current capacity. I have in the past been frustrated with "low cost" hubs that won't charge a phone for example.Hope this helps.Michael

MANUFACTURER ANSWER:Thanks for posting your question here, ck001! Both ports on the 2 port hub share the available power from the one upstream port.If you need any additional information, please do feel free to shoot us an email at support@plugable.com. We are here to help!Thanks!Regards,RozePlugable Technologies

the usb port is for outgoing power, and as long as u have ur own cable, it'll power just like any other USB. very versatile device for 20$. =)

I use a powered usb hub. So I can plug many things into the hub and it has it's own power pack. Then I don't overload the onboard power from the pc.
