USB OTG Host/Charge Adapter


I was doing some research on YouTube and stumbled across a USB OnTheGo host adapter that can also charge a tablet or phone.

Up until discovering that, I thought a large USB hub that required AC power was needed.

One example in the video is plugging in a hard drive that has a split-head cable. One my drives is like this.


Plug the Samsung USB power cable into the side of the tiny adapter (which is shown already attached to an included microUSB male/male cable) …


And the drive has enough AC power through just one of the USB plugs …


.. and the drive is recognized by the tablet and files can be read:


It works with hard drives formatted as FAT32. NTFS requires additional software, probably an app from the Google Play Store.

Here’s the video:

And here’s another video from a reviewer:

Did anyone else know about this before now? Are there other products just like that or is this the only one?

Am I the only one interested in connecting a pocket hard drive to an Android tablet (and maybe phone)?

  1. Hadn’t seen this and no, you’re not the only one who’s thought about connecting a pocket drive to a tablet or phone. It would come really handy, for example, for someone doing some street journalism.

    isn’t this basically just a Y usb cable/adapter? I have been using this for a while now on my hp touchpad to connect external HDDs.

    Hi Mike, no, you’re not the only one interested in that …in many situations I’ve to deal with the cables and especially with all that power stuff as well when it comes to connecting my 2.5″ HDD to my Teclast X98 tablet.

    I got a very nice (and cheap!) mini OTG hub from Aliexpress which comes with a small (USB) cable for supplying extra power to the devices connected. Works like a charm here.

    I know this product! I’m using for watching videos on my Samsung tablet or using a game pad. Very handy when you’re draining so much power (HDD, tablet battery, game pad battery) and you are able to use them and power them up in the same time. Work like a charm :)
