Micro-USB to USB OTG Adapter Cable

Although the item is marketed for Samsung devices, this cable works with other Android devices.  I primarily use this to connect Huawei E1750 3G dongle, I've also tested it with memory card reader and USB flash drive successfully.

This OEM Micro USB to Mini USB (SKN6252) Adapter Cable made to fit my Motorola V950 Renegade was necessary for me to adapt to the USB Mini Cable provided with the Belkin Dual USB Car Charger. It works great and allows me to charge my Renegade while I'm out on long hauls over the road. Great buy, great quality, functions perfectly...

Tested the OTG function with an SD card, and my Galaxy S5 read the files on it. I do have a bit of a concern on the micro USB connector. These after-market connectors appear to have rather sharp and stiff retaining blades on the metal jacket of the plug. This could eventually wear or loosen the USB3 jack on your cell, which of course is a big and expensive hassle to replace. If the engage and disengage steps require too much force, I would avoid continued use of that USB3 plug.  I still have to decide whether or not I will be using this adapter much because of this.

Haven't tested these to see if they're bi-directionally OTG-compatible yet, but they do work for adapting my older wall-warts to my new cell phone.

This is a great cable to use for data transfer and charging of any micro usb device right from your computer.

These adapters allow me to use a single type cable to charge either my phone or tablet. The adapters work great and fit snugly in both tablet and keyboard dock port as well as the micro USB end.

Shipped fast. Really well built. Works fine. This is a great OTG cable for your Galaxy S5. The S5 has a weird usb out configuration and my "normal" OTG for my S3 didn't work - had to get this.

This item worked, but I am still dissapointed that I needed a special adapter and that a normal mini USB cable didn't work

Thank God I finally found this. If not for Amazon i don't think I'd ever find this. Micro to micro is hard enough to find on its own without using an adapter of some sorts for some reason. But to find not only a micro to micro, but a short 8" micro to micro!

I bought this for a Nokia Lumia 2520 tablet. Plugged it in, connected a USB 3.0 flash drive, and watched a high definition movie.

What more could I ask for - especially at such an low price?

NOTE (2014-Oct-31):
The above review is for the&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/MobilePioneer-USB-3-0-9pin-OTG-Host-Flash-Disk-Cable-for-Galaxy-Note-3-N9000-10cm-Black/dp/B00G10XQCC/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">MobilePioneer USB 3.0 9pin OTG Host Flash Disk Cable for Galaxy Note 3 N9000 10cm (Black)</a>, which is simply an adapter to plug a USB flash drive into a micro-USB 3.0 port.

However, now my review is also showing up on an unrelated product,&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/MobilePioneer-Micro-USB-3-0-7-in-1-Connection-Kit-Card-Reader-OTG-USB-HUB-For-Samsung-Galaxy-S5-i9600-Samsung-Galaxy-Note-3-N9000-Blue/dp/B00K4POAUM/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">MobilePioneer Micro USB 3.0 7 in 1 Connection Kit Card Reader OTG USB HUB For Samsung Galaxy S5 i9600 & Samsung Galaxy Note 3 N9000 (Blue)</a>, which is a *card reader*, not an OTG ("on the go") adapter.

I have never tried nor seen the card reader and have no opinion on it. Just FYI.

So I got this with the intent that it would work with a USB-C to MicroUSB OTG adapter.  Unfortunately, it didn't work with my phone so I had to return it.  I checked the actual IR device on my wife's phone which has a MicroUSB port--and it worked fine.  I checked the OTG adapter, and it worked just fine with a MicroUSB SD card reader.

So, if you have a MicroUSB port on your phone/tablet, I'd recommend this (make sure to get zazaremote to control it).  If your phone has USB-C, it may or may not work.

For the manufacturer:  Please hurry up and make a USB-C version!  it shouldn't be *that* hard.

The case worked perfectly except for the micro usb to usb adapter . I had to remove the case in order for it to fit. Not too much of a problem for me as I seldom use it.

Great deal for a couple micro USB OTG cables.

I purchased the pair of these cables so I could use one for my Samsung Galaxy S4 as well as my Google Nexus 10 Tablet.

The cable works to connect USB Flash Drives to both devices without any issues. I've used StickMount to connect USB storage devices to both devices successfully as well as Nexus Media Importer for the Nexus 10 tablet.

Very helpful if extra storage is needed, connected to larger external storage devices (external hard drives, USB flash drives, and even USB to SD/Flash media card adapters)

Rating break-down:
Price Point: 5/5
- $3 shipped for 2x cables is the lowest you'll find.
Functionality: 5/5
- Reliable, has worked with multiple apps and devices without any issue.
Design: 4/5
- Great small & simple little cable.
- Only one minor issue is that the micro USB male connector is a little long and does not plug in flush with the device. However this does not affect functionality and is just a minor aesthetic issue.
Overall: 5/5
- Great price for a reliable OTG USB cable that should work to connect compatible external USB storage to mobile devices.

I purchased this as an adapter for my android micro computer, which was having problems hanging from the HDMI port on my TV with the weight of the USB power cord and the external keyboard and mouse nano adapter. The micro pc came with an HDMI extender, but it was of poor quality and generated scan lines on the TV. Since I began using this cable I am able to use the HDMI port on the back of the TV and position the micro computer for better WiFi reception and bluetooth keyboard and mouse reception. I am very satisfied with the product and the support from the seller.

Works perfect for USB connections on the Droid Mini. I connected a non-powered USB hub with a mouse, keyboard and thumb drive. The only trick is to plug the OTG cable into the phone last.

The item description isn't the best.  I would consider these microUSB to USB-C adaptors.  It makes your microUSB cable into a USB-C cable.  i have6  of these already and they all work great.  Best item to be able to use Micro USB cables with USB-C devices while you still have Micro USB devices around too.
MUST HAVE!

Needed one of these to turn a mini-USB cord end in my "myCharge" backapck (handy back pack that has an enclosed battery for recharging phones & tablets while stored in your business pack) into a micro-end because the female jack on my HTC smart phone doesn't seem to like most micro-USB cables. This adapter had a "friendlier" micro-USB male end, for lack of a better way to put it, and lets me use the mini-USB cable in my pack to charge my phone.
