I see no indication that this device requires AC power. Does this item require an AC connection to operate, as do most high-quality switchers appear to? Thanks much for any help and/or opinion on how important this apparent lack-of-AC concern might be?

Yes, this switch does need to be plugged in. There is no on/off switch so it is always on unless you unplug it from the wall. It is a high quality switch. I did a review and gave it 5 stars.

The proper way of wiring this switch and if it needed AC or DC was confusing to me as well. Here's a good picture showing how to wire it with DC: https://www.greenlivingforu.com/sites/default/files/100_2488.JPG

Hi Keri, no it does not have an AC adapter for home, nor did I notice any place to connect one. It has no on/off switch, so after using it once (and forgetting to unplug it) and burning out my car battery, I never used it again.

This unit sometimes DOES need power. Devices such as the Directv Genie don't give off any power through their HDMI output, so it WILL NOT WORK without an AC Adapter supplying power to the switch. Check if your devices HDMI output ports give off 5V of power. If not, then you need an adapter. The seller is aware of this, but refuses to update their description. Also, it's not helping that reviewers are saying no power adapter is needed. Sometimes it IS needed.

It does not require the use of the AC adapter, it will work without the AC adapter being plugged in. It will only work, however, as good as any non-powered USB hub, meaning, there would be a limit to the amount of power that can be used by the devices connected, some devices will require the additional power, that is the advantage of the additional AC Power source.

I believe mine came with an AC Adaptor. I don't USB would be enough even if it was an option.

For those that purchased an ac adapter...where on the unit does it connect? I can't seem to find a plug connector anywhere. Also, what model adapter did you purchase? This unit would be perfect IF I can power it thru an outlet. Thank you very much! - Brian

Mine came only with a USB cord, no AC plug. Good luck -- it seems to be inconsistent!

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.

The switch does need external power. I removed the switch when it defaulted and blew out the HDMI input on my TV. I wouldn't suggest using it--period! !!!!!

I don't use mine with a external power source. My understanding is that a external power source is required to switch inputs if all input sources are powered off. I have a Chromecast plugged into my switcher so its always receiving power.

To my surprise, the switch did not have a ground connection. I'm guessing that it's not required because there are no exposed connections (it attaches with wires and wire nuts), and that the construction is double insulated.

No switch, but the manual specs it as accepting "AC 100 - 240VAC, 50/60Hz." It also notes you should check that the unit's power cord works "at your line voltage."

The device is powered by the AC adapter. It also works without the AC adapter, but it has its limitations "current-wise". I've used without the AC adapter to connect one mouse and a keyboard and it worked fine. But, because it is a 7 door USB HUB, you might use it to connect other devices, such as hard disks, for example. In this case you must use the adapter. The USB 3.0 cable is that data cable used to connect the device to your computer.

It comes with a 110w transformer, so yes you need power, unless there is something that I am not aware of as far as the usb. I do like them though. The 4 position dimmer is a must, othewise you might find it a bit to bright. Hope this helps.. Jeff

This may sound crazy, but I've read it elsewhere & found it to be true; don't use one. I started having issues so I looked for solutions online. After reading up in several locations I figured out that I had to re-solder a connection & stop using the AC adapter. Ever since, it's been running perfect (until the batteries in the keyboard die that is). It gets it's power from my laptop & I don't have to worry about plugging it in! Hope that helps, good luck!

It does not have power switch. It does not draw power when devices are not plugged in. Better yet, unplug it when not in use.
