[Q] OTG cable with additional power - General Questions and Answers

Hello, I got this OTG cable but it has additional power plug and it might be used with hard disks, because it support additional power for disk, otherwise it wont work.
Question is: if it utilizes external power from AC adapter (stock one from my tablet) does it drain my tablet's battery just like memory stick via regular OTG? Or it just consume power from external adapter?

External HDDs - My experience

Hi All,
I have seen many posts regarding using external HDDs asking which ones work and which ones don’t. So I thought I would share my experience which I think (hope) would cover most situations and answer most questions.
This is what I used:
1. 1TB 3.5”external HDD USB 2.0 with its own power supply (like mostly all 3.5”external drives need their own power supply)
2. 500GB 2.5”Seagate Caviar Blue external USB 2.0 HDD. Runs fine on a standard PC/laptop USB port without any extra power supply
3. 128GB 2.5”Crucial SSD in an external USB 3.0 HDD enclosure. Runs fine on a standard PC/laptop USB port without any extra power supply.
4. 256 GB 1.8”Samsung S1 external HDD USB 2.0. Runs fine on a standard PC/laptop USB port without any extra power supply. A 1.8”HDD is often used in a HDD MP3 player like the classic IPod.
I have used the above using the original Samsung Note 10.1 USB Connector kit, so I can’t make comments regarding other connector kits.
I also use the Paragon NTFS&HFS+ app from the Google Play Store to be able to mount the HDD which were all formatted in NTFS. Without this app I could not mount the HDDs.
My Results:
1. The 1TB 3.5”external HDD connected directly to the USB adaptor and runs fine using its own power supply.
2. The 500GB 2.5”Seagate Caviar Blue external HDD connected directly to the USB adapter did not work. The Note 10.1 produced the error “High powered device”. However when connected via a powered USB hub (i.e. with extra external power supply), then this HDD worked fine.
3. The 128GB 2.5”Crucial SSD in an external USB 3.0 HDD enclosure connected directly to the USB adapter did not work. The Note 10.1 produced the error “High powered device”. However when connected via a powered USB hub (i.e. with extra external power supply), then this HDD worked fine.
4. 256 GB 1.8”Samsung S1 external HDD USB 2.0 connected directly to the USB adapter did work. It appears these 1.8” HDDs are considered “low power” and it did work directly connected to the USB adapter. This also makes sense as these HDDs are used in many MP3 HDD players and could have a low power requirement.
Summary:
I have used 3.5” and 2.5” HDDs/SSDs with USB 2.0 and 3.0 interfaces, and I could get them all to work either directly or with an extra powered USB hub. Using a powered USB hub is a pain but at least it works.
Hope this helps in answering peoples questions whether it is possible to connect external HDDs.
Good stuff...thanks.
You need to use a USB splitter cable and connect the portable drives to an external power source. I do it all the time with my 750GB Seagate 2.5'" drive on the go. I have a portable battery with 2 USB sockets. The external battery provides power.
Besides, this has been discussed at length here and is no secret.
I'll stick to my wireless Seagate 500gb HDD... And when I have time to mod it, I'll make it either 1 or 2 TB....

[Q] Connect hdd to phone + power hdd AND charge phone.

As stated in the title, i'd like to connect my 320 gig external drive to my phone (2,5" laptop hdd in external enclosure - galaxy note 2)
Since it'll be a long flight i'd like to power both devices.
I found a configuration online including a power/data usb y-cable (mini usb - 2x male usb) + usb otg
Now the idea is to connect one male usb to the powersource (5V-2A output, should be enough for both phone and hdd power),
then the other male usb to the phone (via the usb otg) and the mini usb to the external harddisk. (see photo for the idea)
By design of the cable this will probably work:
- be able to exchange data between the hdd and phone
- power the hdd?
But I wonder:
- will the phone charge (or at least get some power to extend battery life)
And (most importantly)
- will it work, or do I risk ending up with 2 fried bricks
halp!
-> attached photo showing setup (only car charger is a regular samsung 5V-2A wall charger in my setup)
On a side note, I did search the forum/google, but now one seems to want their phone charged or mentions it happening.
And I know about the issues connecting a hdd to a phone (galaxy note 2 in my case), but thats not the point of this post.
I bought the cables and found out that:
- i can access the hdd, it has enough power
- the phone wont charge
- no bricks :good:
So,. cr*p.
Oh and I found this:

[Q] Connecting an external hard drive via the usb port

Hi guys. Is there an app out there that makes it possible to connect an external USB flash drive or 2.5" drive to the shield tab via its USB port?
I'm pretty sure you just do, and you'll be good. Strangely I've never had any problems using an OTG USB drive with the Shield. That's what you'd be looking for, by the way... Am OTG cable.
One quick thing to note is, be prepared to need to power the hard drive. The tablet may not have enough juice to power a full hard drive. So if you plug it in and it isn't recognized, try a powered USB hub.
Secondly, make sure you have ES file explorer.
I use a WD ultra passport portable 1tb drive and a otg cable.
I just plug in, open ES file explorer an get what I need an unmount an disconnect.
You'll lose a few percent of battery potential as expected.

Thanks guys. I'm honestly shocked this actually works. I tried it with my WD passport laptop drive and low and behold it works flawlessly. With the research I did in the past with my HTC EVDO 3D, and reading all the comments on various messageboards, I really thought connecting USB HDDs to any Android device would not work. Does it work in this instance mainly because the device is a Shield Tablet? Or is it only because I'm rooted, and as a result any rooted Android device will allow USB HDDs to be used?
OTG and enough power
It just works if your (android) device has an On the Go (OTG) USB connector AND if it gives enough power to your (hard) drive. If there isn't enough power, you need a Y OTG cable and external power source. Many smartphones do not provide the 500mA at 5V they should provide, but tablets usually give enough from my experience.

Nexus 5 OTG help needed

Dear,
I am trying to connect my logitech F310 via USB OTG.
When I plug it in, the power light on the controller is still off. However, when plugged in to the PC, it turns on.
Whenever I plug in a keyboard, it works fine. USB flashdrive power light is on but I can't read data from it.
My OTG cable is only powered via the phone, is it a possible solution for me to solder two extra wires for some extra power?
Thanks in advance!

Accessing internet via hard wire

Could some one please suggest a way in which I can avoid running down the phone's battery when accessing the internet via a hard wired connection into the USB micro port of my mobile phone?
Do you think this would work?

For this purpose I do not want to access the internet on the phone by wireless.

I have tried:
IA micro to usb adapter: Plugable: Model USB2-OTGE100. It does not have a power supply and uses my phone's battery to power the adapter.
A Micro-B usb hub that has 3 standard usb outputs and one power input. It also has a Charge to OTG switch and it does not do what I want as it does not charge the phone at the same time as browsing the internet.
