Can you use an external usb powersource to power this and not plug both usb plugs into the laptop. I only have 3. I use 3 already.

I suspect that you could plug one of the USB cable into an external power source. The question is, "which one"! I would suggest trying the plug on the end to your computer first, then the 2nd plug, (the one with the short lead), to the power source. However, if this does not work, then swap the 2..... One of the plugs is for power only, (no data line in that one)..... However, when all else fails, add a cheap, 2 or 4 port "active" hub to your computer, then plug a couple of your other USB devices to the HUB.... This can cost less than $20.00 This wireless adapter works so well, adding a small hub still makes this adapter the ONLY way to go wireless!

A splitter will not allow the device to have enough power. The device will work on one port but at reduced power. Davids' suggestion is your solution.

I've heard the reason for the two USB's is in case you have a computer that doesn't provide enough power on just one USB, then you have to use two. It seems to work fine with just one USB with my Compaq (HP) 6730s laptop. I've also tried in on my HP desktop and it also works with just one USB. My thoughts are, try it with one and if it works, great! If not, then you'll have to use two.

You need to use at least one usb plug in on computer to allow for communication. Look into a usb spliter possibly as you are using all of your ports. Good luck. The EnGenius device works awesome.

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.

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.

Yes, you can use either the adapter or the USB cord to get power.I use it to conserve USB ports.

The chromebook does have one powered USB outlet that this would work with, but your chromebook will only be able to power one device at a time. In other words, you wouldn't be able to use this at the same time as a USB powered external hard or optical drive. If the Lapdesk is the only peripheral you'll be using, than you shouldn't have any problems. Hope this helps!

It is "powered" through the USB port, so expect it to provide only as much power downstream as it receives. In particular, it may not power multiple of those portable hard drives that get power through USB, but it probably will power a single one, depending on how much power it receives from the port it is plugged in.

You'll need to pull in your laptop separately. This dock does not have a power source. Its small and handle though and I'm pleased with my purchase.

I have used two of my USB 3.0 ports to use it. One for power the other for data.

I would see no reason why not. I use mine with both usb 3 and usb 2 pc's with no issues. I use it with a 500gb 2.5 sata drive in a usb 3 enclosure as well as the same setup in a usb 2 enclosure as well as flash drives in both flavors. It has worked flawlessly with both but is noticeably faster with the usb 3 interface on the laptop. I remember there being some question whether it would power an external hard drive through the port, without an external power connection but all of my usb devices power fine through the hub.

No, it doesn't need a separate power supply, it can draw the power from USB port on a laptop. If you intent to connect it to an USB hub, make sure that the USB hub can provide sufficient power. Non/low powered USB hub will not work.

Yes, you need to use 2 usb ports for the extra power. The supplied usb Y cable has about 5 inches of slack between the plugs. If your laptop only has 1 usb on each side you will have to get an extension.

Technically, the answer is yes; it gains its power externally--it has no internal power source. However, in common parlance the answer the answer is no, since it gains its power through the usb and does not have a separate power cord or connection.

So if I'm understanding your question correctly, you can plug in a power adapter into the mini USB port to charge the device and at the same time use the USB 2.0 port to power and use an external powered USB hard drive.

If you hook the the additional USB to a power source, I don't see why it wouldn't work. Just make sure the additional power only cable is the one you hook to power only.

I'm aware that the drive works with both USB cables plugged in. However, since the choice is between using up an extra usb port and a usb extension cable (my laptop has exactly two ports: one on each side, so the default cable won't reach); buying a usb hub; or finding a power adapter that will work with the unit, I would prefer to have the extra power cable run to where the drive will "permanently" sit.

Hi. With this device, you do not need any external power. The device brings it all included and takes what it needs directly from their computer. It works excellently. Regards. Vincent.

I use two all the time at home on my HP laptop, powered by a USB hub. It's great having 3 screens! I even had three connected to it at once. I uploaded the pic ( users pics of the device ).
