Best Buy this USB is my first most loved purchase because it is my first time using this type of devise. I just plug it into my computer and the other end to the other plugin that goes to the TV. Wow I watch TV movies all day long and I can go to my Hotel and use it on their TV too so convenient.

I'm happy to share my experience with the HDMI adapter, which I found to be quite effective. It consistently provided a clear and stable connection, making it perfect for various display needs. The adapter performed admirably in every task I used it for, ensuring a seamless experience. Ultimately, I no longer have a use for it, but I would recommend it to anyone in need of a reliable HDMI adapter.

Don't know why Apple is moving away from multiple ports but this adapter is super helpful. Never seen a thumb drive that is anything but USB. Plug into any printer or TV and not have to hassle with passwords. This little adapter comes with me and my new laptop so I can actually use it.

The adaptor works as I had hoped. I'll bring it along on trips, particularly international travel, when I need to connect my MacBook Pro to various devices (e.g., projectors) that are not USB-C.

I was really impressed with the product - it was straightforward and didn't have any complications. It turned out to be quite resourceful, which was a pleasant surprise. I searched through multiple stores, but I could only find this particular product at Best Buy, and the price was really reasonable considering what they were offering. I would definitely give it 5 stars!

I use this adapter with my MacBook Pro, and it works perfectly. The HDMI connection gives me a clear, stable display on my external monitor, and the USB port is great for connecting a flash drive or other accessories. I love that I can still charge my laptop using the USB-C port while everything else is connected. Small, lightweight, and super useful. Highly recommend it!

Use a wireless charger with the device you attach

This does not provide enough power to also charge a phone while a wireless mouse/keyboard are connected to the USB port and an HDMI cable is connected to it and a smart TV. My Samsung charger and USB-C cable does work with it, but it draws more power than it passes to the attached phone to keep it charged.
It does work very well if I placed the phone on a wireless charger. This allowed me to work around the adapter's power issue. I tried a competitor's adapter and did not experience a charge issue.
It is a great device for using Samsung DeX, but power your device with a wireless charger. It is still a next adapter if you have a wireless charger and need the USB port for a wireless keyboard and mouse.

I bought a lenovo yogo 920 laptop and it lacks ports. This was great. Plugs into the C-usb and splits it into 1 USB, 1 HDMI, and 1 C-usb. I have had zero problems with this. Also they have this product a little cheaper on the manufactures website so don't forget to price match!

Great device. After plugging the device into the laptop’s HDMI port, connecting the usb-c power cable to the laptop, then the laptop’s usb-c power cord into the device, instant detection of the two monitors as well as the laptop’s was flawless.

I am extremely pleased with this j5create USB Type C to HDMI external video adapter with Power Delivery. This product works exactly as advertised. I plug the main USB type C end into my phone (Galaxy S21 Ultra) or tablet(Galaxy S7+), hook a mouse into USB Type A port on back, and plug in monitor with HDMI port, and that's it.
Now, there are some basic limitations of the adapter. it supports up to 4K 30HZ or 1440P 60 HZ. If you have a HRR Monitor, this adapter will not be able to take advantage of that high refresh rate. This works perfectly for Samsung Dex at 1440P 60HZ and gives the ability to use a wired mouse or one with a dongle. I have found Bluetooth mice do not always work with all the different apps of mobile operating system. So I prefer wired.
The USB Type C port on the back is only for hooking to power adapter to charge devices hooked in. You can get up to 60 watts combined when hooked to a compatible charger which is basically any USB Power Delivery compatible charger. Pretty much all PD chargers support the basic standards that would apply here. Although worth noting, I have a 100 watt 4 port PD charger with 2 Type C and 2 Type A ports that supports PD 3.0, QC 3.0, PPS, and Samsung Super Fast. Both Type C ports are fully capable of delivering 100 watts, or any charging standard in between. When I plug just the tablet or phone in to the adapter, I get full power charging (45 watts) but as soon as I plug in my mouse , the charging speed drops immensely. My guess would be 15 watts or less, charging time increases accordingly. My guess is that even though the adapter claims to offer up to 60 watts, that is with one device hooked in. With 2 devices it seems it defaults to basic charging speed. Sometimes depending what I am doing the phone or tablet will not gain much charge at all.
Overall I am happy with this adapter, I have used many other adapters and cables trying to find the best one. They all have compromises somewhere, This product by j5 Create seems to be as good or better than therest.
