Does this device require a power supply to be connected? Is it usb based or does it have an adapter for a electrical outlet? Thanks!

It has 3 HDMI ports only: display out, input1, and input2. No power or USB.

Steffi - device does NOT require power. Draws enough power to operate switch and indicator lights from HDMI cables.

This device does not require a power adapter. The limited power that it consumes is delivered via the HDMI input.

An adapter is not supplied. I have no problem with the 3.0 USB connection. External power adapter port is available. Very happy with this drive.

It doesn't have a bettery or external power supply. Takes power from USB only.

No USB port. In addition to your device, you will need to have the USB cord and the corresponding electrical cord to utilize this adapter.

The unit comes with a power adapter but you don't need to use it. I have a ext HD, wireless mouse/ keyboard combo controller and my UPS USB cable hooked up to it without the power adapter plugged in.

It doesn't come with an AC power adapter. Instead, it has two USB cables: one to interface with the computer and the other supplies power to the unit.

Yes it had the power adapter. Issue I had was my external HD would not work. Would not recognize it. Thumb drive worked OK.

no, you need the included ac adaptor(is a 12v output), usb is only 5v output.

It requires a power adaptor to be plugged, but one comes with the item, however you will need an AC outlet nearby as the power cord is only 30 ins long or you can attach it to an extension cord.

You just need a USB charger to power the unit. The power supply voltage is immaterial.

The device does plug into an electrical outlet. Is that the question you are asking?

While I used it without the power adapter temporarily, I would recommend plugging this in. It will give you better longevity of the device, and it won't use extra power from your computer. I am not entirely sure whether you have external drives is a factor. I assume you are talking about external HDD or DVD drives?

No power supply needed, just a USB port to plug into on your system. The only issue I have with this product, it keeps disconnecting, it doesn't lock in very tight, so I always loose connection on it, which can get annoying at times. There is no port for a power cable at all.

It requires standard USB power which is 5 Volt, 2.5 Watt, 100mA. Mine came with a 100-240V 50/60Hz 2 prong wall adapter, but I have never used that.

I don't believe this has a USB connection (just as it doesn't have a 120V power inverter), it just seems to have the 12V outlet.

The AC adaptor is not needed, it use the power from the USB3 which is adequate. However, it does have a mini DC plug that use 5 volts if you have to use the adaptor. I do not use this plug at all for this device or any other device that using the USB2 or USB3.
