3-Port Micro USB OTG Hub Adapter (3 USB Ports + Power Port) for Fire Stick 4K, PlayStation Classic, Raspberry Pi Zero, Sega Genesis Mini, S/NES Classic Mini and More - Black

I put together an ADS-B tracker with a blue Nooelec RTL2832U SDR and a Raspberry Pi Zero 2 W. I discovered along the way that the Pi's wifi wasn't very strong so I wanted to add a USB Ethernet dongle but I was short a USB port. This hub plugs into the left USB port. Ethernet, and two other USB devices (like the SDR) go into the hub. Power can be plugged into either the Pi's right USB port or the hub. Power is plugged into a 15W Anker USB-A charger. I definitely recommend it for this particular application. Combined with a right-angle Micro USB adapter and a couple of rubber bands and you've got a fun project.

I bought this to go with an Onn streaming stick which uses the older micro-USB for power. Makes it possible to plug in up to four USB devices including a flash drive loaded with video files.

This is a super-niche use-case, but if you have an old Lenovo Yoga Book (the thin one with the Intel Atom processor, Halo keyboard), then this could be useful! I wish this would charge it while within Windows, but at least it gives me more USB-A ports. Interestingly enough, I learned that if you leave it connected to power, it will charge while the tiny laptop is shut down! I finished my task (moving stuff from USB flash drive to the device) and shut it down while leaving it connected at about 70% battery. After a few seconds, I saw the charging light flashing next to the plugged in microUSB port. I left it there for a few hours and came back to see the light was no longer flashing. I turned on the Yoga Book and it was at 100% battery! Nice. I don't use this little guy often, because it's slow and a bit inconvenient with no other expansion ports, but this little hub really helps. I suppose the best option would be the official Lenovo T-hub they used to sell, but that's hard to find at a reasonable price.

...or to be more specific, Fire TV 4k Max 2nd Generation (2024 release) which supports external USB storage. Was already using a wired ethernet adapter with my Fire TV Stick but the existing adapter would not allow for adding other USB devices. For more flexibility, purchased this three port USB hub and a separate wired ethernet USB adapter instead of the integrated two port USB/ethernet adapter. Installed everything six months ago, and other than an unrelated error message (see below) have had no issues. 1. Connect Fire TV Stick to HDMI port 2. Connect this three port USB hub to the Fire TV's micro-USB port 3. Connect the Fire TV's power cable to the hub's micro-USB port 4. Connect USB devices to hub - ethernet adapter, flash drives, mouse, etc. (see picture) Note: There is an unrelated error message if you choose to format a flash drive for conventional storage instead of allowing the Fire TV Stick to format the flash drive For Applications. If the Fire TV stick does NOT format the flash drive For Applications, then you will always-and-forever see an error message pop up that your Fire TV device cannot store applications on your flash drive, since it is not formatted For Applications. This error message is considered normal and should be ignored.

This worked great with our Amazon fire stick so that I could use a keyboard and mouse

Works on "Fire TV Stick 4K Max 2nd Gen" (w/ 720P 60Hz TV) for "Ethernet Connection" & "128GB USB Media Storage". Network speed not much different comparing to previous configure. - Overall "Good" & No problem found so far.

This device is perfect for a traveling photographer. It allows me to make backup copies of my photos (and view the jpg versions on a nicer, larger screen) without having to travel with a laptop. I can use my Android tablet or even my Android phone, instead. This very small and light USB hub plugs into my 2017 Samsung Galaxy Tab S2 Android tablet. I connect a USB flash drive and either a cable to my camera's USB-out connection or a tiny SD card reader with the card from my camera. Then I use a file manager app (the default Samsung Files app works fine, as does the default Android Files app on my phone - which I actually prefer to the Google Files app) to select all the files I want to duplicate and copy them to the flash drive. File transfer is not fast (200 files totaling 2.79 GB took 5 minutes and 50 seconds to copy, or about 8 MB/s [64 Megabits per second]). I think the slowness may be partially the fault of the 512 Gb Sandisk Ultra Flair USB 3.0 flash drive I used, since it slows down drastically on large write operations even when connected to a PC, apparently to prevent overheating. Since it starts fast and then slows down, a larger transfer might produce an even slower average transfer speed. But the bottom line is that for one or two transfers of, say, 2 to 10 Gb per day, even this slow speed is good enough. I can do something else for five, ten, or even twenty minutes while a day's worth of photos copy themselves. In my 2.79 GB test, none of the devices got more than just barely noticeably warm. With a small adapter (micro-USB to USB-C; it MUST be "OTG" [USB "On The Go"] compliant), I can plug this hub into my Pixel 2 phone and transfer files in the same way. So if my tablet dies or I want to travel *really* light, I don't even really need the tablet. Managing files on the small screen of a phone is doable but not as convenient. Note that you CANNOT get a USB-C hub and use an adapter to connect it to a micro-USB tablet or phone, because apparently no one sells a USB-C to micro-USB adapter that is USB "OTG" compliant. So if you want to use a hub with devices that have both types of connectors, you must get a micro-USB hub and an OTG compliant adapter to convert it to USB-C when needed. You apparently can't go the other way. Given this limitation, there are not many competitors to the AuviPal hub reviewed here. You can plug a charger into the hub, as well. I believe that will provide power to the attached USB devices, but not concurrently to the tablet or phone. I have not tried this feature and do not anticipate needing it. Advice: be sure to "eject" or "dismount" the flash drive and camera or SD card before disconnecting. This tells the tablet or phone to finish writing any data or file allocation table entries to the flash drive or SD card. I have already found that just yanking out the flash drive when the file transfer appears to be done can cause it to produce error messages the next time it is plugged into a PC, although interestingly, I did not actually lose any data. The Samsung and Android Files apps make the "eject" or "dismount" command hard to find. On the phone, you can see it by tapping the notification bar on the Android home screen, then the "more" link on the notification for each USB device. I never did find the "eject" function on the Google Files app. Physically, the hub seems reasonably well made, but nothing special. I had been attracted to some USB-C hubs with solid aluminum housings, but as noted above, a micro-USB hub is more flexible. This one is plastic, not premium but probably fine.

Allows connection of firestick to Internet (hardwired) and tv, and also extra memory stick added.

Funcióna excelente en mi fire tv4k

funktioniert tadellos

Entgegen anderer Negativen Bewertungen, funktioniert der Adapter mit dem FireTV Stick MAX 2gen ohne Probleme. Schön ist vorallem, das kein weiterer USB adapter dazwischen genutzt werden muss. Einfach zwischen die Stromverbindung einbauen und fertig. Bei der LAN Geschwindigkeit kann ich keinen Unterschied zum LAN Adapter von Amazon erkennen. Grundsätzlich sollte man jedoch wissen, das fast alle FireTV Geräte die Formate NTFS exFAT etc. nicht unterstützen. Von daher funktioniert nur das eingeschränkte FAT32 und entsprechende USB Medien mit diesem Format. Tolles Produkt und würde es wieder kaufen ....

Vraiment pratique, fonctionne meme sur un vieux tel de 2014 !
