I want to power two devices from one USB "outlet" on my desk. One of the devices is regular-size USB and the other is micro USB. Will this do that?

No. This product is not designed for that. I got this product for my external DVD burner. I'm not sure what else it is used for, but I don't think you can do that.

No. The extra USB connection is to provide more power to one device than a single connection allows. Some hard drives need more power and that's what this cable is for.

good question. mine cuts out with one usb drive but works fine with another. My toy won't work at all unless it is plugged in to power which defeats the portability aspect. :(

No. The cable is only made to increase the power to a device by using two usb port to provide power to one device.

All multiport USB chargers will split the power between the ports but this one is 3A. One port will get 2A and the second 1A so it is sufficient to power all new devices that require 2A charge (like iPad and large screen smart phones) and use 1A port to power second device without compromising on time. Just make sure to use original device cable.

You need to plug both in because one transfers data and the other supplies power. If you can only connect one then you need a usb splitter.

No, not at all...the red colored usb is a power supply only- meaning this plug is made to connect only one device (that requires drawing its power from the computer to use it) to your computer/printer. ps: I have searched high and low and not found the cable to connect 2 computers to one printer, best thing to do is to set up a network with a router and connect the devices to that network.

You should be able to use two laptop, but you need to check the amperage draw on each one. The two USB ports are two different amperages.

The two USB male ends are part of the same cord so I imaginethat the only function this serves is to increase power. It draws power from multiple ports because traditionally USB ports don't supply large amounts of power to devices, but many newer computers and motherboard USB ports have a larger power capacity. Only using one USB, most likely, will not be a problem, assuming the HDD or SSD isn't huge and doesn't consume outrageous amounts of power.

I recommend you try the 4 port USB 3.0. It requires no external power. However, charging devices through this port is not recommended. I have one and it has worked with everything I have tried in it.

No, that is fixed. So in one standard wall outlet with two outlets you can only use one of the devices.

Yes, but you need to have two open usb ports, one of them usb 3.0, with the power being plugged into the usb 3.0. USB 2 doesn't provide enough power.

If you are using a low-power USB connection then the second cable provides additional power. You probably won't need to use it.

Yes, with two USB cords you can charge both devices. I personally wouldn't expect to get to 100% charge for both, though.

A couple of the answers are not correct.Requirements are:A. one USB 3.0B. USB 2.0 MIGHT require two, MIGHT work with just one (will depend on you port)C. One USB 2.0 and an external power supply (Not included), if one USB 2.0 isn't enough and a second USB 2.0 isn't available.

Yes. 2 USB at the same time and in addition another AC plug. All will power simultaneously.

Not sure, but will charge an iPad so using the 2nd USB port aught to work. The specification section on the Amazon site is actually quite thorough, as is the PowerGen website. I am quite certain this will work just fine however.

There are one cable USB to an -Mini USB (http://en.wikipedia.org/wiki/USB) in the packet. Its Powered by the USB, no need for extra power.
