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.

It's been charging my tab for about a month now with no problems at all, but I'm not here to argue, if you feel that you know more than I do. I've charged the tablet using that adapter from my laptop, PC, and Energizer XP4001 Power Pack.
You might also search the forums, as I'm not the only one to recommend and use this item.

Ahh thanks! Was wondering why it wouldn't charge via my USB port.
(In fact using my Samsung Focus USB adapter for the outlet doesn't seem to work either... I need to use only the Samsung Tab USB adapter)

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?

Is that through the orginal AC adapter or through PC USB?

Turning off the tablet and charging it via USB works, but it takes forever!

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

You don't need to embarrass yourself by saying you're an idiot, It's very childish and the second time you mention I'm supposed to be smarter then you. I'm sorry you take this so personally.

i just use the supplied cable and it charges via usb on my computer. it shows not charging, but it basically trickle charges when the tab is both on and off

Dell Venue Pro Charging issue and not recognized on pc

I recently bought a used dell venue pro unlocked 32GB version. I see few issues, hope some one can help me with the resolution.
Phone charges only when it almost discharged or dead.
If I remove the phone in the middle of charging, it does not continue to charge.
Once charged, battery discharges very quickly.
Zune does not recognize the phone. I am able to enter download mode, but not able to update any software.
Any help is greatly appreciated.

Did you acquire a new battery or is that the original battery?

If you can obtain another battery, try swapping it out and see if the behavior is the same.

Is the cable you are using the one that was acquired with the unit? Does the cable you are using to connect work as a sync/data cable with other phones? There are cables out there that are just charging only as they short out the data pins and/or ground the data lines. if you can lay you hands on an OEM Dell or an OEM Nokia Data Cable you should be able to sync with Zune, unless the data pins on the phone are bad or shorted out on the handset.

The cable bundled with the VP is a standard microUSB cable.
The pins are supposed to be shorted on the charger itself, shorting the pins on the cable itself isnt the right thing to do.
That said if your cable can be used to connect any other microUSB device, it should work (as far as the cable is concerned).

I do not have the original cable or charger ..I am using the cable and charger that I got with Nokia Lumia 710..I am able to sync and charge my Nokia phone perfectly..
It it is a port problem then I would expect it not to charge even once ?

Charging VIA USB is POSSIBLE (MZ601)

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.

My Xoom model MZ604 'OEM HD Dock' connects via the pogo pins, usb and hdmi. I always assumed the power was supplied via the pogo pins.

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.

I believe the USB portion was simply to help with alignment for tthe pins

What exactly is up with the USB-C charging port?

Hello,
I've tried to find a clear, straight answer online and while I have found info regarding the USB-C standard, I can't find an answer to my question.
I use a mirco usb plug to charge both my current mobile phone and my android tablet.
Does the smaller port in the OnePlus Two use the same sized micro-usb port for charging? I understand that the USB-C port is the larger port on the other end of the cable. Maybe I am wrong about that.
Right now I have several micro usb chargers that I use to charge my phone and my tablet, and I'd like to know if they will be able to charge a OnePlus Two. I don't mind if the charging is slower, but I'd just like to know if it will fit and charge.
Thanks!

No in my sense,as far as my knowlege goes, USB-Type C is altogether a different technology,so you will need a special adapter for OTG too..

No.....a big No....the port they are using is nothing more than a new plug on the phone side of the cord. The other end of the cable will plug into all your old USB ports. So you will need to use the OP2 cable but the end that does not plug into the phone will plug into any current USB port.
They did not include any of the good things that come with USB C, they just put the USB C plug in the phone and on one end of the cable.

Thanks, friend. That's clear. This is a drag. Right now I have several charging cables that power all my stuff. Now if I get the OP2, I'll need two cables for home and two for the office. That's a negative in my book

Based on the release video they said an adapter would be available older USB cables so that might be an option for you.

Good to know. If the adapter is small and inexpensive, that would help a lot! Thanks!

Yes you can. It's also helpful if you want to use a wireless usb controller since it needs the power boost. Here's what I use: https://www.ebay.com/itm/Left-Angle...361414?hash=item48830dbec6:g:rQsAAOSwMmBV5RRC

Thanks for the confirmation. 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.
