Customer Feedback

1. This cable is a good value, being longer than other competing listings and of course it works fine.

I use this to connect a USB hub (with HDMI and charging) to my laptop. It’s powered by USB-C so I plug my charger to the hub and then the hub through this extension cable to the laptop and it’s charged fine. The long length allows me to hide the hub away and keep my desk clean.

2. ve bought this for my Nintendo switch so I don’t have to keep it in the dock I have a separate stand for my Nintendo switch making it easier to take out and it keeps it cooler because one of the events is not covered up all in all this lead has been a really good buy five stars and awesome and yet again Amazon’s been a really good place to shop

3. I have bought many other brand extension cables, but I am not satisfied with its length and transfer speed. Belker’s extension cable fits my needs.
Its Data transmission speed up to 5Gbps. And it is 1.8M, I can extend everywhere I want. One thing surprised me is it can even offer us lifetime warranty that I haven’t saw any other company can give such promise before.
Thank you and I recommend it. Hope it can work well for me.

4. Probably the best type C cable, yes I know its a cable but having cheeped out and bought a cheaper cable from a well known auction site, You can see the speed difference. I have screen shot the difference between the 2 cables which are worlds apart. Speeds were taken via a samsung type c flash drive which does have slow write speeds, but I use the drive to move images between laptop and pc and read speeds are more important to me.


 5. I purchased the Belker 2 in 1 charging Adapter for my new pixel 3 XL. The Pixel 3 XL comes with a 3.5mm dongle that plugs into the USB C port, but it does not allow charging at the same time. I’ve found that, when listening to music for a long while, I often have to stop to unplug my headphones and charge my phone. I bought this adapter to prevent this problem.

After several week of use I’ve found the adapter is very high quality, made of metal and not plastic. It’s very easy to plug both your headphones and power cord into the adapter. It also allows rapid charging. I have not noticed any deterioration in sound quality when plugged in. I would definitely recommend this product to anyone with the same issue.
