[Q] usb charging w/o plug adapter - Galaxy Tab Q&A, Help & Troubleshooting

is there a way to just use the usb cable like when I plug the gt into my computer to get it to charge?

Try to turn off your tab then plug to your computer usb

Even though the icon looks like it thinks the tab isn't charging, it does actually charge anyways. Leave it plugged in overnight with the screen off, and you'll see. My Nook Color does the same thing. It's just that charging with normal 500ma USB is slower than the 2A regular charger so they want to discourage you from charging that way.

[Q] Whats With Charging This Thing?

When I first got the phone earlier this week, I could plug it into the charger in the wall just fine with no issues, it would just charge. Now suddenly it started telling me USB connected and goes to the MTP screen and of course locks up the phone.
I can of course bypass this by switching the phone to mass storage mode, but since I have Kies and use it occasionally, it would be nice to not have to switch that setting each time depending on my charging/syncing situation.
Why would it have not locked it up with the MTP screen originally when charging from the wall but now it does? The results are the same whether its plugged into the wall or the USB port on the computer. I have two Captivates bought brand new on a family plan, both do this now with any combination of chargers and USB cables, wall USB port, or car charger. Neither one has a common application installed since the other is my girlfriends who hasnt done much to it yet, so Im blaming the phone itself for now...

Interesting. I just checked with my BB charger and they dont do it using that charger, but they do it as soon as I connect the stock charger again.
Im wondering if its a voltage sensing circuit thats tripping due to the different voltages which should be applied - either wall charger or USB port. Maybe for some reason my wall chargers arent putting out enough voltage and its thinking its a USB port, but the BB charger is putting the right amount of voltage out?
Am I on base as to how it differentiates between wall or USB port? The number of pins obviously doesnt matter as all the cables have all the pins in them, unlike some charger cables which only have the power and ground. The only thing I can think of is that it uses the amount of voltage/current to tell the difference and create its reaction.

Sounds like a problem with the stock charger, maybe usb cable alignment. My iphone wall adapter does this with the samsung cable but the samsung wall adapter doesn't, same with my car charger from att. Also I have a $5 walmart car charger that has a cable that splits into both a mini usb and a micro usb that isn't a real usb cable, it's charge only. That cable has no problem on any wall or car adapter. I believe the phone detects if its connected by checking voltage on a data pin (just a guess really) so if a nonstock charger is used it assumes that it is a computer. But it may also be a data signal that is given off by the charger.

did you try a new charger and if so, did it work? I've had my captivate since Thursday and on Thursday it charged and everything fine, but then yesterday,
a) no computer I connect it to while recognize it, no matter what I have it set too and have latest drivers installed
b) if I charge it, after I unplug it, it locks up to black screen and I have to remove the battery to get it to work
c) I also have an in-dash touchscreen monitor in my car that has a usb port because it works with an ipod. I plugged the usb into to use it as a car charger, unplugged it, same thing
d) it did say usb connected after it was unplugged, but I switched from mass storage to ask on connection and it went away
so is an actual wall charger the solution?

and now I unplug it, and if it locks, it will not unlock, just black screen
I have to take out the battery and then only way to get it to turn back on, is to plug it back in the wall

^^^Ouch that's not right, if you can't figure it out you may need to re-flash or just bring it back under warranty, or insurance

USB Debugging in wall outlet?

I plugged in my phone to charge it this morning and all of a sudden when i connected it to my wall charger it went into USB Debugging mode? This is a first for me and it kinda scared me a bit. I then unplugged and plugged it back in and it went into charging mode. Can anyone explain this? Has this happened to others?
I believe if the charge current is low, such as 500ma, the phone assumes it is connected to a computer. Doesn't mean anything other than a slow charge.

thanks for the reply.
im sure it was just a fluke. ive always charged it in this wall outlet. i replugged it and it works fine
has this ever happened to anyone else?
This happened again. Can someone help me out here?
Happens to me all the time. As the poster above mentioned, shouldn't be anything to worry about.
You can turn off usb debugging if it bothers you or use a different usb cord as some have a tendency to do this because they reduce current flow too much

That happens to me when i try to use the iPhone charger.. I'll try to jailbreak it..
Download "Spare Parts" from Market. In the Battery Info section, you'll se if the phone detects your charger as USB (PC, below 500mA) or a Wall charger (700mA)

So if it detects my wall outlet to be below 500mA then the power going to that wall outlet is low?

Let me test.. But my iPhone charger is 1000mA!! And my phone detects it as DC, acording to Spare Parts (USB), and if i switch to the original charger, it turns into AC..
If the phone controls how many mA/Volts can receive, and the charger is detected as DC, it will be charging at the same speed as if you use the PC USB, no matters if you uses a 200000mA charger...
BTW, sorry about my english

The charger has wiring that shorts the data lines - this tells the phone it is a wall charger and not a usb port - the usb port carries data, so the lines are not shorted. This controls the amperage - If it shows AC - the phone detects the shorted data lines and the phone draws about 700mA. If the phone does not detect the shorted data wires, the phone only draws about 500mA. In all cases the voltage is 5V DC.
I have a 2A car charger. With a regular cable (non-shorted data lines) the phone thinks it is on a USB port. I short the data lines and the phone says AC charging.

I am using the regular charger that came with the phone. Does this mean the charger is faulty?
I get this all the time. Probably because I'm using the little white USB to wall converter from my old iPhone. I still get a good charge, though I've noticed it charges about 2x faster if I turn it off and use the black charger from Samsung. That way I get about 20% an hour, otherwise about 10% an hour.

If you are using the charger and cable that came with the phone, and the phone settings page says you are charging via USB and not AC - then either the charger or phone is faulty.

Charger specs

I'm looking for an extra charger for my nc. What I need to know is what is the mah output of the stock changer so I can get one that had the same rating. Our can someone link me to a cheap stock charger.
The output is 5volts / 1.9 Amperes.
Edit, it is written on the charger btw, you could probably have checked that your self .
Where can I get a charger with the same specs? I don't want to spend $20 but if I have to I will just buy another stock one.
I have a 5v 700mah charger that I bought for my phone. Will that work or is the rating to low?
That will work, it just wont charge as fast...

FYI: I tried using my HTC usb charger with the nook usb cable and it will not charge. The charging light flickers.
Thats what I'm worried about
There is this cable from boxwave with a dongle off the end that you are supposed to use to charge from USB chargers. Why would anyone need this?

It is charging, just not as fast and the device doesn't notify you of it. HTC usb wall plug chargers are usually 5volts and 1amp, the nook requires 1.9 amps to charge properly.
/mr
There are no spec listed for that charger so it could be a 700mah or it could be a 1.9a charger.
How many of you guys recommending underpowered chargers actually have any electronics background?
The nook charges when connected to a usb socket on a computer, which provides 500ma as a high power device. So your 1000ma charger is twice as good as using a computer.
In order to get 1900 ma, the nook isn't using stock usb stuff in the charger... but normal usb works just fine because, well, the standard requires it to...
4000 mAh battery should charge fully in 2 hours on the nook charger, 4 hours on the htc charger, or 8 hours on a computer...

Good to note that there's a bug on the NC that makes it appear that it's not charging, when connected via USB connection, but it really does charge.
regular micro usb chargers from cell phones will charge the nook even when it says it's not charging.

The NC will charge from my Droid's power adaptor even though it does not show it to be working. It will take a lot longer to charge with a standard 0.5A USB power adaptor.
In theory, it should take about 4 times as long to charge from standard USB instead of the B&N charger.

It does work. It's just charging slow so you can't necessarily tell. Also. There will be no indicators on the nook to show that it is charging but i'm pretty sure it is. Leave it plugged in overnight and see.

charging using usb

Hi,
I bought the nook but live in France. Can i charge my nook with my HTC Desire power supply and cable? The nook usb cable doesnt seems to be "only usb".
Thank you.
You can probably use a standard USB power inverter and generic cable. If it's safe for your Desire, it's almost definitely safe for the NC. However, some cables might randomly not work.
A standard micro-USB and charger will work, but it is slower than the Nook charger. I routinely charge from a powered USB hub at the office.

Ok thank you!
Hi I am also from Europe and I checked that Nook Color have a multi 220/110 voltage charger

You need only plug adapter
Yeah, that what i use for now. As i have my htc power supply alway connected to my wall i wan't to put the NC us power in his box.
I tried one of those cigarette light -> USB adapters for charging the nook in my car. When I plug it in, it wakes up. But it's not charging. Anyone have any idea? I'm using the Nook cable, btw.

It's charging, just slowly. Charging from a standard 500mA USB jack doesn't cause the "Charging" indication to appear in most battery monitors on the NC, but if you leave it there for a while with the screen off and not doing anything you should see the battery percentage go up a bit. It takes about 8 hours for a full charge via USB. It's enough power to either run the NC if you're actively using it OR to charge the battery, not both at once.

How can i replace the normal charger?

My dog just ate my standard mini usb charger. Can i charge my phone with normal usb cable (while connected to latop/pc) or is it problematic for the battery life?
Can I use any other mini usb charger like HTC desire?

I assume this is a troll
If not I'd like to see some pictures of it.
Yes you can use any other MICRO-usb charger, not MINI. USB cable works as well
Haha! unfortunately no troll He cut the cable into two pieces, so it is completly destroyed and the connector is damaged too.
Im pretty pissed, dont have the money to rebuy a new one So ill stick with my usb connector. Just wanted to go sure that my phone wont take any damage while charging with my laptop
I connect my phone to my pc via MICRO-usb cable. It charges phone also but it's slower than normal charger.
