Micro USB OTG Hub for Raspberry Pi Zero 4 Port High Speed Sync and Extension Cable Adapter Also Works with Android Tablet Raspbian Jessie Linux

Using it to connect raspberry Pi to Victron MPPT, and has been working great.

All ports worked as expected on my Raspberry pi ZERO 2 W.

I needed additional USB port on my Raspberry Pi Zero W and this little gem works great for that application.It’s reasonbly priced too.

I bought this hub for my Raspberry Pi Zero. I found out, the hard way, that not all USB hubs work with the Raspberry Pi Zero. However, this one works perfectly. It's small, inexpensive and works out-of-the-box. My only annoyance is that if you're using it with a Raspberry Pi Zero, the micro USB plug is upside down. So when you plug it in, the top of the device will be face down on the table, and you'll be looking at the bottom of the hub. You could twist the cord, in order for it to be right-side up, but it's extremely unnatural. The cord is short and the device is light, so twisting it doesn't work very well. The device keeps trying to flip back over. Besides, who wants to twist their cord?Other than the fact that it plugs in upside down, I would easily recommend this hub to anyone who wants to use it with a Raspberry Pi Zero.

I purchased these to use with my Pi Zero 2 W. I am able to use them to connect a keyboard and mouse. They have also worked with USB drives. So far they have worked as described.

Use case:I wanted a USB-A hub for charging my AirPods and heart rate monitor at my Peloton bike.It took me several months with my Peloton bike (original not Bike+) to realize its tablet has a micro USB port that I could use for charging. I had been charging my AirPods and heart rate monitor at an outlet in a different room and that was sometimes annoying as I would find myself clipped into the bike and only then realize I had left one or both of those devices charging in the other room. So that's where this handy little hub came into the picture.It functions perfectly and I particularly like how thin it is. I was a little worried that whatever hub I got would look bulky or out of place on the aesthetically pleasing Peloton bike but this little guy blends in nicely. With just a tiny piece of double-sided foam tape I had this hub mounted and it's hardly even noticeable. The only minor complaint I have is the red power indicator light inside the hub. The hub's black plastic is translucent so the red light diffuses through. It is somewhat helpful to know the hub is plugged in and receiving power but ultimately unnecessary. I solved this by putting a piece of black electrical tape over the area where the light was shining through the most.This isn't a particularly special piece of hardware but worthy of praise for how well it worked for my needs.

I bought this after one reviewer said he used it with his 2nd Gen Fire TV Cube and that's exactly what I needed it for. Well, he was right, it works great, and I couldn't be happier. Don't be put off by the small size when you first take it out of the box. It just makes it easier to move around when you need to add addtional devices. Excellent product at a great price.

I saw the "May 15, 2018" 1-star review. I do not doubt the complaints therein; there have been many quality complaints about products from Hong Kong or from elsewhere in China through Hong Kong. Poor documentation and missing specifications about current and voltage. For example, I cannot charge my Samsung Galaxy S8 phone on this hub. Their web site (makerspot dot com) is of little if any help.My unit arrived in good shape (no loose connections or other flakiness). Just lucky? However, the host-side (USB On-The-Go) connector does not engage as well as the Pi's power supply connector (different vendor). This did not detract from performance but it gave me a few minutes of concern.Note that I only had to use this HUB for roughly 15 minutes, enough time to get the SSH daemon running on my Pi Zero W headless Raspbian installation. If I use it consistently in the future and develop more feedback, I will update this review.
