They worked great with the raspberry pi I got them for

I bought this to try to get a boot-looping Firestick to break out of it. This Firestick was beyond help. However, this cable does work with another Firestick as expected. I was able to hook a keyboard to it with this cable. This tells me the cable works but that one Firestick was toast.

Great Gadget! You get what you pay for however. I paid under $2,from "Eamall". The connector going to phone is rather loose, could be because i have used my phone so much. The power and accessory port are very snug. You must use your power supply cable with this, at least on a Vzw Galaxy S3. I made sure I used a high power charger. I prefer the Note3 charger I have, which is 2000ma or 2a. I have read allot about shorting out the usb port, unless you use the power cord. Average usb devices use 500ma power and having a 1.5a or 2a, allows the device or devices to be powered as well as the phone. I say better safe than sorry. This is faster than WiFi! I have successfully used a flash drives, a 2.5" external drive, keyboard, a usb serial ttl programmer and a mouse! I did not try the USB to Ethernet, but have read your luck will vary. This is a must have, and you will be happy you invested in a OTG Cable. A vast majority of phones and tablets support OTG.

You may use a USB Hub, but will have to use power for phone and a power cord for the hub itself, which is allot of wires. I have several flash drives, my best being the HP and Sony. Those were 8GB and 4GB, I also have a 16GB SanDisk. When I tried using without power, I was unable to access the drives. Sometimes I got a status bar notification, mostly I did not without that extra power. I have 23yrs computer experience and was absolutely tickled with the mouse on a phone! Why I don't really know, guessing because its feels weird, but it worked excellent. I have had no issues with this doodad on 4.3(JellyBean), 4.4 (KitKat) both TouchWiz and ROMs.

I can say the adapter had no effect on speed. The speed does fluctuate allot, suspect OS settings. I can say that I am rooted and use X-plore or ES File manager, both excellent with different interfaces. I also use 3C ToolBox for tweaking the phone, but there are many other Kernel Tweakers available. I am using a custom kernel too. I like DKP Kernel for the extra features. I have my phone scheduler set with: Internal SD -ZEN 1024KB read ahead and SD Card - SioPlus 1560KB and Flash Drive with SioPlus 2048KB. The newest version supports flash drives and or OTG. The benchmarks are insane for the speed of these schedulers. I was reading in the mid 250MB. Now actual performance is better with these tweaks, not mind blowing though. My SD Card is a Samsung Evo 64GB and the best investment ever made for the phone.

I am reviewing this to add my review seeing as how many good and bad reviews there are of this product. The cable i recived is of great quality as far as i can tell made with sturdy conectors and wires that dont feel flimsy. I bought it to use withe the nvidia sheild tablet and the cable dose both data and charge at the same time. It should be noted that OTG cables will not charge your device if the usb device pluged into them is hogging all the power from your power cable. If your power cable supllies 2 amps of power and the usb device(for instace my portable hdd) uses 2amps of power then the tablet will not get any juice. To sove this type of issue i use the otg cable in conjuntion with a powered usb hub so that the charge cable only powers my tablet and the hub poweres all usb devices. To address other reviewers haveing no luck or not working cables i only have three things you may consider, also for buyers to consider when looking at this cable or others.

1.) Dose YOUR device support otg function. Also more importantly dose it support otg function WHILE charging(my sheild did not support charging wile using otg function till a update, were the release notes stated it as a suported function).

2.)What type of usb device do you plan to use with the cable dose it have high power requirements if so will your tablet or phone get any power?

3.)When buying items from sellers other than amazon are they a reputable seller with good feed back or are you getting a knock off? I state this due to this is not sold from amazon at all and there are about 100 sellers with ruputations from 100% positive to 1%.

I used this cable to playback movies stored on a Sandisk Cruzer USB flash drive. In combination with the Nexus Media Importer software from the Google Play Store, all I had to do was plug the OTG cable into my Nexus 7 and my movies were automatically displayed for playback. I used my Nexus 7 to watch movies during a 10 hour flight to Italy and this OTG cable made watching movies very fast and very simple. Video playback was smooth and reliable and I was able to carry many more movies with me on an external flash drive than would fit on the internal Nexus 7 flash storage. The SanDisk Cruzer fits so perfectly in the OTG cable it is easy to forget it is there. The OTG cable leads are short and very flexible which allowed me to just fold the cable ends behind the Nexus 7 so that they were out of the way. This cable provides a female micro USB cable for attaching your device to a charger or powering a larger USB device. The female connector will allow a Nexus 7 or other host device to be charged as long as the OTG function is not in use (i.e when a flash drive is not connected). I was unable to charge the Nexus 7 while watching movies. This is a limitation of the device firmware/hardware and not a problem with the cable. Fortunately the Nexus 7 has the battery life to operate during the entire flight. This OTG cable did everything I needed to do and appears to be holding up well during my long flights.

I primarily purchased this cable for the USB OTG adapter function and that part works GREAT with my phone (an LG Stylo 3); however, the additional charging port will NOT charge my phone. That is a disappointment but since I purchased it primarily for the USB OTG function, I decided to keep it. The overall quality of the cable seems fine but it would have been nice if the charging port worked because I'm recording audio from a USB audio interface via the USB OTG part of this cable and that can be a steady, fairly high drain on my phone's battery. On the bright side though...if you have always wanted to record audio via USB on an android phone (it must be one that supports it...look for "USB OTG" and USB HOST" in your phone's specs), this cable will work for you.

I used this with a Hisense Sero 7 Pro, It has a custom ROM and kernel so it has the ability to take advantage of this cable. Using this cable I can charge my device and run anything from the USB port on the cable.

This cable works perfectly.

Now I have to say that when using this plugged into my device it only charges at 900ma. This is not the fault of the cable but due to a limitation of the kernel on my device. When it see's something plugged into the USB it automatically limits what the device see's and sends the rest to what ever is plugged into the USB port. If I only use the pass thru on the cable with nothing on the USB port it will charge at the full 2amp rate.

So when playing a movie over HDMI from my device and having the charging cable hooked up to a USB drive I will only be able to play movies for about 5 hours before having to stop and fully charge the device, It will not keep the charge at 100 percent. This is much better than not having the Y cable hooked up. I used to just use a standard OTG cable with my USB drive and I could only play movies for about 2 hours before having to stop and recharge.

I just got this little guy, relatively recently, and have only tested a couple things a couple times, so I can't really attest to it's build quality/longevity. That being said, in my short testing, it seems to work as perfectly as it can, as far as I can tell. Cheapy sd card reader with 32gb micro sd card? System sees it, without any coercing. Astro does not, but I think that's a problem of permissions. Copying files to the device ended up being a little fiddly, but not too much.

As for my other use, so far... ehh. I can get my Audio Technica AT2005USB recognized and working in Evernote, and working with better sound in an app designed for recording from USB microphones. (UsbAudioRecorder) As for the stock video app? ... well, if it's possible, I'm totally in the dark. I can run the aforementioned USB mic recording app at the same time, but, at that point, It's all starting to get a little bit silly. There's some color of static-ey noise (I know... really technical.) even in the special app, that isn't there/as prevalent, when recording on my computer, so I kinda doubt I'll be using this to record much audio, on the go. I haven't used any other USB OTG adapters, but I feel like it's unfair to judge this one for that noise problem, as it's something that I always expected from a cheap adapter.

For the price, ($1.60 with free shipping, at the moment) it seems like a five star item to me, but if/when I encounter failure due to build quality, or unreasonable issues, I'll try and remember to update this, since that's where the value proposition is made or broken.

Sin problemas funciona muy bien

J'ai acheté ce cable USB OTG - Micro USB pour mon Fire TV Stick afin d'y ajouter une clé USB ou un clavier avec pavé tactile. Ça n'a pas marché le premier coup car j'ai branché mes appareils sur le port micro USB femelle (avec adaptateur) et l'alimentation sur le port USB standard. Il aurait fallu brancher l'alimentation sur le port micro USB femelle plutôt ! J'ai testé le port USB standard en utilisant une souris puis une clé USB. Tout fonctionne ! Avec la clé USB il faut utiliser l'app ES Explorer pour voir le contenu et fair jouer la musique, les vidéos ou les photos. Le prochain test que je vais faire est d'utiliser le port USB pour un adaptateur USB/Ethernet pour augmenter la vitesse de transmission des données (au lieu du WiFi). Amazon a mis sur le marché son propre adaptateur USB/Ethernet vendu au prix d'environ $20 - ça peut être utile au cas où le réseau WiFi n'est pas assez puissant (la bande 5 GHz est cependant à exploiter si la bande de 2.4 GHz est trop lente).

Great item does what it's ment to do

For those who are wondering, this product has the below uses...

1. Connect to Mobile phone as OTG cable for accessing files from a pen drive

2. Connect to Amazon Fire TV Stick (via OTG) to connect pen drive, and at the same time, connecting a charger to power the Fire stick. Why connect pen drive to Fire TV stick? it can help us expand the in-built storage of the Fire stick, and also we can store moves on the pen drive and play them via the Fire stick. Some even use it to store Android apps (apk files) on the pen drive and access them through the Fire stick and install them on the stick. This is for those apps that are not available directly in the app store of the Fire Stick. Nice usage scenario.

3. You can also use this to connect a Game Pad (Game Controller) to your Android phone and use the Game Pad (Controller) to play games on Android phones. Again, nice utility.

I tested all the above scenarios, and this device worked very nice.

Hope this helps. If this review helped you make your purchase decision, just hit the HELPFUL button. Thank you!

It works
