Charging VIA USB is POSSIBLE (MZ601) - Xoom General

After a certain person (on XDA) forcing me to prove that charging VIA USB is possible, I suppose I should share with all of you guys as well. I have a MZ601, so it's an original XOOM (you don't say right? hahaha), a few weeks ago I brought a car charger that has multi-tip, so it means you can swap out the adapter and such. I tested it on my XOOM and it worked, so I came to the conclusion that the XOOM official charger was 5V but in reality when I was chatting to solarnz about it, he mentions it was a 12V and to my surprise it was. Anyways the point is if you can convert or buy an adapter pin to usb for the XOOM it is possible to use any source of USB power to charge the XOOM.
Here are some pictures so you get the idea:

So there, I hope you guys can find it useful and not flame me like that certain someone.
Edit:
I should also add, charging via USB is pointless and slow only for if you really need to. Unless you got an adapter that outputs 1.0A + it probably be faster than standard usb, but what's the point if you got your original charger?

Always good to have options.

cool slow but if u need some power it should help

very interesting post, i have a car charger but not multi pin...didnt know that it can charge through pc usb

Thats really good to hear, as the pin is fragile and i hate it. I have an old samsung tablet usb charger and to my surprise it did work.

Where can I find these adapters?
I've always been sure that plugging the xoom to a usb 5v 1A+ charger would have worked but couldnt find a bloody adapter that fits that unique pin

You can not charge xoom by usb.
Usb is not connected to the xoom battery.
Stop the question

That's not exactly charging via USB.... that's using a power tip adaptor to charge FROM a USB power source.
This is not exactly news.

Rats, got me all excited, even tried a couple of my usb chargers (didn't work of course).
Should change the thread title to: Charging VIA USB is ** NOT ** POSSIBLE (MZ601)

The charger tip is not that unique actually it's the same size as the NOKIA N71 mobile

Thanks for this info. Now I know we are certainly able to charge our xoom via USB. Eventhough it's very slow, but always good to have this option.

I no longer have my Xoom, but if I remember correctly, the Motorola dock for it charges via USB... the standard plug goes into the dock, but where the Xoom sits, there is only HDMI male and USB male connectors.
FWIW: My mother now has my old Xoom and she accidentally bent the pin inside the Xoom where the normal charger goes. The only thing that will work now is the dock to charge it until the port can be fixed.

That's correct. Just checked what you call the "pogo pins" on my OEM dock and they are at 12VDC. Contrary to the title of OP, I don't think it's possible to charge via USB.

No you can't, USB is 5v and the Xoom requires 12v to charge.

Oh, btw, you CAN charge via USB, but it's just reaaaaally slow. If you use the tab while plugged in, you might not even gain charge... just slow it down. The battery in the 10.1 requires much higher amperage than USB can provide.
Just an FYI. A regular USB 2.0 extension cable wouldn't work with the Transformer (which also has a short data cable). USB 3.0 extension cables reportedly worked though.

USB charging

I've noticed when I have my tablet plugged into my computer via USB it doesn't appear to be charging. The battery icon is showing a red lightning bolt. This is different than when I have my tab plugged into a wall socket.
Working as intended or..?
Your PC USB port can't supply enough juice (500ma max) compare to your wall socket (>2000ma) to charge while power the tab. Turn the tab off and your will get some charge off the USB port.

The focus charger is rated only about 700ma (same exact one as Captivate/SGS), marginablly better than PC USB. GT 10.1 has a rather large battery and hence it requires much larger charge current. You don't see any laptop get charged via USB, do you?

And you are not the only one who is waiting twice as long before his tab is fully charged. Then we can open a topic "Why does it take so long before my tab is charged?" As foxbat stated: You don't see any laptop get charged via USB, do you?
So if I say your adapter doesn't work its just as accurate as your answer it does work.

Hey, I'm not here to argue with you. I'm just an idiot.
Go about your business, and don't listen. I'm ok with that.
First of all, not all USB ports are equal.
On many modern PCs, the USB ports can deliver more than 500mA over USB if required. This is definitely true for pretty much all Macs since 2007, and quite a few mainboards from other manufacturers (see this article for some background).
Secondly, I've had one of these adaptors for quite a while now, and have used it regularly to charge my Galaxy Tab 7" which uses exactly the same power supply and cables as the GT 10.1. I can categorically state that when using this adaptor, it the GT7 does charge from a Macbook Air and a 5000mAh external battery that has a 1A output USB port labelled for an iPad.
Whilst it might not be as quick as the wall charger, it is definitely much faster than attempting to charge the GT7 from the same devices without the adaptor, even if the device is in use.
I've not formally tried to charge my GT10.1 with it yet, but I did check to see if the "not-charging" indicator went away (which it did), so I rather presume it will work much like the GT7.
Regards,
Dave

Yeah, any cable should work for charging. Usually it's data that is a problem because sometimes cables won't have those pins even connected.

Why do some companies insist on supplying crippled USB cables?
On where to get them, any mobile (cell) phone shop should have micro USB. Just about every maker – with the exception, of course, of Apple – has switched to this connector for charging and data.

[Q] Pogo pins and OTG question [simultaneous charge & OTG?]

I'm wondering if anyone knows if it's possible to have simultaneous OTG & charging with the use of a pogo pin charger?
For instance, plug in a usb OTG into the main microUSB charging port, and use a pogo pin charger [either make one or buy when they are available], and have a flash drive, or hard drive plugged in, and charge at the same time with the pogo pin connector?
I used to have a Nexus 7, and via a custom kernel, and a OTG charging cable [basically a regular OTG with additional power wires & connector for charger]. But I think it would be simpler to use the pogo pin approach. The only thing I'm worried of however, the kernel might disable OTG while it charges via pogo, or perhaps disable charging while OTG is enabled. I guess in this case, we would need a modified kernel to achieve simultaneous OTG and charging.
Here is a link to one of the first Nexus 10 pogo charger cables and it makes this claim:
"You still can power Nexus 10 while the USB port is otherwise occupied for data uses. It is fun & convenient to have MagNector to free up the USB port and charge faster."
http://www.ebay.com/itm/MagNector-N...ader_Chargers_Sync_Cables&hash=item20ce4990a6
So if that statement is true than the answer to your question is Yes.
eBay item is no longer available..
However, I know how sellers often make unfounded claims like that. So while it's probably a good sign, I am not convinced it's true. If anyone is fortunate enough to have a pogo charger, could you test it out with a otg cable and let us know the results?
Or if you're a kernel hacker, maybe take a look at the kernel source code and tell me what you think?
Also if anyone has a link where I could read about pogo pins for the N10, I'd like to read it. I'm interested in trying to make one, if they don't make any low-cost ones in the near future.

I know it's not the original question, but it looks like that would be possible with a modified OTG USB cable. Sounds like you already have something similar.
I was thinking about this for using my n10 for larger video recording when away from wifi. Just need to hook a battery up to the OTG while its plugged into the thumb drive. It takes a charge off my laptop when connected via the otg usb, so it should work as well with the correct setup voltage/wiring .
I would also like to know the pin designation for the pogo plug. If you can do the same setup as the one above, with the pogo... There would be less chance of damage to the tablet on the go......

I know a nonstandard OTG cable [a OTG charging cable, basically the same as a regular one, except it has female USB only connected to the charging pins] and a modded kernel allowed for simultaneous OTG + charge on the Nexus 7, but I'd rather not have to deal with that, as getting a separate pogo charger seems like a better option.

It has to be a moded kernel to access the data in read/write mode? Nothing to do with charging, and correct?
What I was considering is a battery/usb hub combo. One that plugs into the micro usb port and the battery actually has a female usb port for the thumb drive (need root to write to the drive, but not to stream from it). Amazon carries lots of external batteries with micro usb connection and the female usb port.
I agree, the pogo would be much simpler and still allow data through the micro usb.
The pogo would be much better for portability for this type of use especially if it allows for faster charging. If no one has the pin layout, guess I'll wait to get mine and test them myself. 6 pins on the n10 itself so it's not a standard usb pin setup?

No, on the Nexus 7, if you plug in a OTG cable [which basically grounds a certain pin, the only difference between micro OTG and micro to full size USB adapter], it disables charging through power pins, because it needs to send power to OTG device, for example, a flash drive. It needs +5V power.
So the kernel mod was to disable the output of power, so that it could instead receive power and charge, from the charger. [The charger also 100% powering the OTG device]
Even if you have an externally powered hard drive, it needs power to turn on, even if it uses a wall adapter for the actual power to run the device.
Here is the kernel I was talking about: http://mehrvarz.github.com/usb-host-mode-power-management-nexus7/
it was made by a rootzwiki user. some discussion here: http://forum.xda-developers.com/showthread.php?t=1934722
Check the images of the USB hub on the 1st link.
Just for the heck of it I plugged a USB cable connected to my PC into the Nexus 10 while the pogo was also connected. The Nexus 10 showed up on the PC as it normally does in the file explorer and I can transfer files back and forth as usual. I went to Settings -> Battery on the Nexus 10 and it showed "Charging AC". I then unplugged the pogo cable and the status changed to "Charging USB". Plugged the pogo back in and the status switched back to "Charging AC". Then to make sure the pogo was actually doing the charging, I watched 2 hours of Netflix with the screen set to full brightness. The battery went down only 2%, so I'm pretty sure the pogo was doing the charging.

Thanks for your test. However with Nexus 10 connected to pc it is not in otg/host mode. You need to connect for example an usb memory with a otg cable to test if charging work with host mode enabled. There seems to be some discussions going on claiming pogo charging is disabled in host mode on Nexus 10 as well. It would be really really stupid if that's the case and I can't for the world figure out how they could put this limitation in the kernel.

Yes I tried that and the pogo would not charge.
EDIT: I bought a couple of OTG Y-cables on ebay (1 male micro usb end, 1 female micro usb end and a female usb end) to play around with when I saw they had a fix for the Nexus 7. I tried one on my Nexus 7 (PA rom and Timur kernel), connecting the female usb to a powered usb hub that has 16gb sdhc card plugged into it. Then connected the female micro usb end to a spare micro usb charging cable and the other end of the charging cable to the usb hub. The male micro usb end gets connected to the Nexus 7. I fired up the Nexus 7 while in the Asus pogo dock I bought for it and it charges the Nexus 7 while also allowing the OTG connection. I tried the same setup with my Nexus 10 (PA Rom, Ktoonez kernel) and pogo cable and it worked. The Nexus 10 charges through the pogo cable while the OTG works also. With the usb hub I'm using with the Nexus 10, I had to plug the charging cable into a charger wall wart. I don't think the old hub was putting out enough power to power the usb device. I let them both run over a day like this. Ran some RomToolBox app backups on both them and they both are charging on the pogo pins while doing so. If you go to system settings -> battery it shows "Charging AC" on both.
The galaxy nexus already has a custom kernel that supports OTG + charging (via a y-cable):
http://forum.xda-developers.com/showthread.php?t=1835720
In that thread (and the link in the OP there) there are discussions about porting that kernel to the nexus 7. Also, this modified kernel is (currently) for 4.1.2. Unfortunately I am not smart enough to do this myself (especially we are now dealing with the pogo cable and the USB); I do hope to let everyone -- especially the developers! -- knows about the possibility in view of the gnex kernel.
Is this an issue only with Disk Media over OTG, or is it with anything (controllers, etc.) over OTG?
If anyone is interested read my edit a couple of posts up.

I had been using this cable (https://www.amazon.com/Tendak-Micro...07828&sr=1-2-spons&keywords=otg+y+cable&psc=1) for my Nexus 7 I had installed in my dash, and for some reason it just doesn't work with my HD 8. Even with the USB DAC not connected, the cable registers power, charges for about 30 seconds, then says it's not connected to power anymore. don't have this issue with the Nexus, or with any of my other power cables, but that's the only OTG angle cable I have.
I'll try the one you use, but I'll have to use a Micro USB angled extension to make it fit in the dash. Unless someone else knows of an OTG y cable with an angled plug that actually works for the HD 8?
Update: I've bought two additional otg cables from Amazon, and one will work for the usb device, but doesn't charge the tablet, the other charges the tablet, but won't work for the usb device. After testing both of these several times, they both started to have the same behavior as my other one, it shows charging for a few seconds, then stops, but continues to power the usb device. If I connect a normal power cable it will stay in "fully charged" mode forever and Automate reports power is connected. I'm starting to get really frustrated. I'm pretty sure it is actually charging, because when I left it connected like that for an hour, it never moved from 85%, but then as soon as I plugged in a normal charging cable it started "charging" at about 6% per minute, and said 100% within 3 minutes. Not even a QC 3.0 can do that. I'm so confused.
