AuviPal 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

Works as described. The power port acts as a hub port also (i.e. it's a three port hub with two being USB A and the third the 'power' micro USB port). Though it states up to 100Mbps, it's worth stating it again. I missed it when ordering as was pretty disappointed since I get 150 over WIFI. Thought it was gigabit. I think this might explain why it's such a frequently returned item.

Works with TiVo Stream 4KTiVo Stream 4K has a micro-USB port and a USB-C port, and comes with a micro-USB power cable. Their website SAYS the USB-C port is for wired ethernet and USB storage. This OTG device did not work with a micro-USB to USB-C adapter into the USB-C port. My router did show a 100Mb connection on the port but no activity, so it was getting power but not data. The power cord worked fine using the same adapter into the USB-C port (TiVo implies the micro-USB port is the only way to power it)To get it to work, do the following in any order:*Plug this OTG device into the TiVo micro-USB port*Plug network cable into OTG device*Plug USB devices into OTG device*Plug power cable into USB-C port on TiVo, or the micro-USB port on the OTG device (I was surprised this worked)To play your own video files off a USB drive, install a media player app (ex VLC) on the TiVo and use it to play media (don't reformat the drive in a TiVo-only format)

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.

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.

Works great

Works flawlessly thus far.(1) Male Micro USB plug wired to (3) Female USB ports. On the end of the housing is also a Power-USB for a total of (4) USB ports.The wire is very short, which makes it nice and compact.note: The one Power-USB port cannot transmit data, but the other three USB ports can.
