    15ft USB 3.0 A Male to A Female Active Extension Cable

    Take USB 3.0 to new lengths with this USB 3.0 Active Extension Cable from Monoprice!

    With data transfer rates up to 10 times faster than USB 2.0, USB 3.0 is quickly gaining in popularity. However, although it has a higher voltage and current level, passive cables are still limited to a maximum length less than 15 feet.

    This Active Extension Cable draws power from the USB 3.0 bus and uses it to boost and regenerate the data signals, ensuring that full SuperSpeeds can be maintained to much longer lengths. By combining two of these extension cables with a 3 meter passive cables a total length of 13 meters (42.6 feet).

    This 5 meter (16.4 foot) cable is backwards compatible with all previous USB versions and any USB equipped device. It has a USB 3.0 A male connector on one end and a USB 3.0 A female port on the other end. Per the USB 3.0 spec, the plastic inside each connector is colored blue to distinguish it from connectors designed for previous USB versions.

    This cable works perfectly! - but not if you don't understand USB power!

    Pros: This cable is very well built and generally high quality.
    Great length.
    Excellent, firm connectors.

    Cons: Too many people review this cable as "poor" or "so-so" because they don't understand how USB works, or the power requirements for their USB devices and what it means to USB power when you use an "ACTIVE" cable.

    (Which at these lengths, you -must- use an active cable for USB 3 devices to work correctly!)

    This cable works flawlessly if you know what you are doing.

    Ignore the reviews that state "it won't power my device" blah, blah...

    Read, on...

    I went through many "passive" (regular) USB extension cables before purchasing this "Active" USB 3 cable.
    I tried to avoid using "active" cables due to the difference in price from the non-active cables.

    Big mistake. You cannot have a USB cable longer that about 9-10 feet (usually 9) before you start having serious errors if the cable works for your device at all.

    Too many people are buying the cable and trying to run USB devices that can be powered by the USB power.
    YOU CAN NOT DO THAT ON AN ACTIVE CABLE! The reason the cable is active is because it's USING the power from the USB3 port to run a repeater in the cable. This is what makes it capable of being the length it is without a problem.

    You therefore can only use this USB cable with:
    1) Devices that require extremely low power (e.g. USB memory sticks)
    2) Externally Powered USB HUBS

    That's how it's SUPPOSED to work.

    I placed my SiiG USB 3 externally powered Hub on the end of this cable and connected a Rosewill UASP capable HDD enclosure with a 3TB SATA III drive installed. It recognized the USB3 Hub, and the drive, and then my PC connected to the SATA III Drive using UASP ove USB 3 and the speed was BLAZING fast, as expected.

    Of course all other USB devices worked flawlessly too. Many WITHOUT the powered hub.
    (Of course all those devices were VERY low power USB memory sticks.)

    Pros: Works as a USB extender for flash drive, external hard drive with separate power source, or input devices. But you can just buy the regular 15ft USB cable for those uses for a fraction of the cost of this cable.

    Cons: Does not provide enough power to run portable external hard drives whether USB 3.0 or 2.0. The specs should provide more info regarding compatibility.

    Does not power portable external hard drives.

    I bought the 15ft usb 3.0 active extender cable to connect a portable usb powered hard drive. I discovered that it did not provide enough power through the USB 3.0 port on my computer to power the hard drive.

    Alternatively, the monoprice USB 2.0 16ft active cable 8751 will work to power a USB 3.0 or USB 2.0 portable hard drive but at the 2.0 speed.

    Pros: works for extending a SUB 2.0 keyboard, but that was not my purpose.

    Cons: I wanted to extend an ASUS USB 3.0 self-powered monitor. The monitor does not receive the signal. I tested to see if the cable was bad by extending a keyboard and that worked. But it does not send power to the monitor.

    Pros: From now i don't know unless you want to use USB 2.0 device with it ... When working i got near sustainable 80mB/s transfer rate from the repeater 1 to 2. Not bad!

    Cons: The USB 3.0 hard drive are no longer detected and that's for HD operation that i bought them. It begin to loose connection when it finish by detect the hardware plug in it. And now nothing happen when i plug a usb 3.0 hard drive.

    I bought 2 of them maybe 2 years ago. It work good at the beginning. After that a small displacement of the cable making the connection drop especially near the head. I tought it's a slack connection but everything ok. Now it is usefull for usb 2.0 gear or use it as a rope ...
