Customer Ratings & Reviews

I required an extra USBC port for my portable laptop extended screens. I tried two different types that I bought from online marketplace and they were crap. I couldn’t get the 3 screens to work until I bought this item from Best Buy. That’s all I am saying. This item works for me. It provides the extra USBC port for my display monitor and a charging port to keep my laptop charged.

It functions flawlessly, allowing for uninterrupted viewing throughout the day without draining the battery.

The male goes to the laptop. One monitor in the DP/USB and the power cord in the Power in.

After functioning for five months, the device suddenly stopped delivering power to, and audio from, an iPhone. J5's response to a support request revealed that their reps don't even understand the purpose of this product or how it works. For example, one told me that it needs 100 watts to function, and that it's not designed for phones (but only for computers and tablets). This is absurd, and directly contradicts what J5's Web site says. 100 watts is the MAXIMUM power that the device can pass through. Also, its primary use is for mobile devices that have only one port, and thus need it to charge and deliver audio at the same time. Why would you even use it for a computer, when computers typically have headphone jacks and don't typically charge with USB-C? When the device functioned, it did so just well enough to be acceptable. Its audio output level is very low compared to other sources, so you need to turn your amplifier up quite high. It also suffers from buzz when you disconnect your phone; this isn't a huge deal because typically you will then switch to another source. Audio quality was acceptable, without the automatic-gain problem that cripples Belkin audio adapters with profound noise.

Good adapter and do the job but sadly stopped working randomly after a month

Great adapter to add a second screen and expand your workstation, especially using an Apple laptop.

Exactly what I was looking for, but it was apparently not carried in the store, and the sales person I talked to had no idea what I was asking for. I found it online and ordered it myself.

Needed a new adapter after purchasing new Iphone. Works fine, just as I hoped.

Great device for laptops with limited connection ports.

It gets the job done! I’ve always had good success with my iPad and this dongle

Works great! As promised, Getting exactly what is shown

Perfect- I needed this to get extended monitors to work with my laptop and this was perfect

This is magic adapter I can use it to charge my M Mac+ extended monitor

Used to connect my desktop to double monitor setup. Worked like a charm.

Didnt work for me. It 4k supportive so i think it was too much for my 1080 portable monitor.

Needed it for work. helpful if you lost your maglock charger

I assumed this would allow one USB-C port to connect 2nd Monitor and USB-C port to my Mac AirBook. It didn't work. I had to return it

I thought it would charge my phone and watch at the same time. It's not made to do that.

It works good and I do love it great for travels !!

The C input was for power only. It didn't do what I needed it to do.
