TESmart HDMI Switch 4K 3x1 HDMI Switcher Box with IR Remote, Supports 4K 3D HD 1080P for Xbox PS4 Roku HDTV Blu-Ray Player

What product does not come with a power adapter? This one! Despite saying, "No Need Extra Power" it appears to need it as per the instructions in the package that says, "not supplied." If I cannot find a 5V adapter among my many old ones I will be returning this.

I wish I used this as soon as I got it because I would have returned it (and I purchased 2 for a couple of old lcd tv's!!). It needs to include a power source otherwise there is a drop in video and audio capability when a source is connected to it. There is an option to plug a power source but I have no idea what kind of 1/4 inch cable jack to use (watt, amp, etc)- it should've included it or been a usb type. It may work with regular HDMI but not 4K.

Requires HDMI cord and power supply and could not find a power supply that worked and the information included does not help you. I had to send it back. Be wary. Purchased one that did not require additional equipment

This product has worked very well and was very easy to set up. My one complaint was that my PS4 skipped in and out slightly. I haven't experienced that issue often or with other inputs plugged into the device. The remote is easy to use and input can be changed on the device itself.

Worked, and then it didn't...when a Nintendo switch was hooked up plus an Xbox. None of them would respond to the the input change when pushed. When I would unplug the output HDMI and plug it back in it worked. But then once more changing input on the box would make me have to unplug and plug in the output to see any picture...not worth it so far.

Easy to operate... glad i only had two things to switch on that circuit.... hdmis wont fit in all terminals but switch automatically senses connections... maybe i just need thinner hdmis ????

Works exactly as depicted. So far it does everything you could ask for in an HDMI sitch. Seems like a very good value for the money.

Not sure why this product came without a power supply. It will not power three devices even if those devices have their own power supply. Ie., roku, firestick, cable box. Now ill try to buy a power supply for it I guess.
