Will this provide power to USB ports if not connected to a computer? I want to install these in a conference table.

Yes it does coz it's powered, meaning it has a power adapter that provides the power to it rather than only through PC or so.

Possibly....You just have to plug the USB plug into a power supply....like a laptop or a phone charger.

To supply power to this caerd, you have to have a powered USB port available. Plug the included cord into your existing on-board USB port and plug the other end into the small connector in the middle of the card.No added power for things like wireless mouse adapters or thumb drives, but needed for things like external drives and cell modems.

I'm betting it won't work. Power is needed to run the controller on the board and it maybe be more than the usb bus can provide.

Yes that should work, though you would be limited to the power levels delivered by a single USB port.

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.

No external power required. Only needs a USB port with enough power. Most standard USB 3 ports should be adequate.

I think you mean USB output because the signal goes out to the monitors. If so it should work fine.

I think you might possibly be able to connect then together using a usb hub with multiple alternative usb connectors to get a stronger current, unless they have an in-built system to specifically prevent this.

it gives u usb 2 ports. i wouldn't try to run hard disks from these ports, the only power is usb power

It will provide power without being connected to a PC and can charge some items, however devices that require higher current to properly charge (tablets, etc) might be a problem.

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.

Don't know. They are there to recharge phones, tablets, or whatever else you need charged. Haven't had any problems with the USB ports.

No. It is *not a powered hub* and for the record, this is not just a "hub" in the normal sense. This is to switch up to 4 USB devices between 2 computers. I use it for a mouse, keyboard, and microphone and for those devices it works fine. This includes a Razer mouse that does not fully work with at least some other KVM solutions.

The usb port is output power only. It will charge cell phones, mp3 players and other devices that use a usb to charge. So the answer to your question is no.

No, it will only work with a computer and cannot be used as a hub for power.

Yes, I bought one and use it to power a USB hub that my printers are connected to. Works great, no problems
