Hi,
I just got this item from ebay: New USB Charger Converter Adapter for Samsung Galaxy P1000 Tab
http://www.ebay.co.uk/itm/190706474031?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649
it says in the specs that "Connects Samsung P1000 charging cable with 2.1A current output power adapter."
I tried with the tablet 8.9 and it really charges from the computer USB, unlike a without this converter that only keeps the charging.
Im using A1 kernel and Im just wondering if there is any risk? or someone have experience this kind of adapters earlier?
ERM. Doesn't the tab come with a 2.1amp out brick in the box?
Both my 10.1 and 8.9 came with the same 2.1amp brick.
If you want faster charging, you gotta find a kernel that supports fast charge. AFAIK, AOKP builds this in and can be swapped on and off in performance settings.

Im talking about an attachment that makes your tablet to charge faster from the usb port of the computer
Sent from my GT-P7300 using xda app-developers app
if you're charging from a standard .5A usb 2 port you won't charge any faster as this won't magically turn your .5A port to a 2.1A. what it will do is allow you to fast charge from a source that can output more power, like an aftermarket usb charger or possibly a usb 3.0 port.

I have it with me, and it does the magic, normal usb cable doesnt charge at all ( on a1 kernel 1.7.3) with this device in few minutes i see an increase in charge.
Im just a bit worried since i havent seen any of these around, if someone else have used them

Yes...It really only works with its own stuff. Some have claimed to have it charge from usb when it was off but I have never tested it.
Are any other similar devices able to charge through usb? Netbooks or laptops? Usb was not designed to be a big power source. Some hard drives require two usb connectors for just a hard drive.
Sent from my mopho
From what i have read in other threads it has to do with the voltage required and how Asus wired their plug.
Use USB 3.0 cables and it will work fine. Also use a USB 3.0 port on the pc for slow charging.
Usb 3 cable works fine here...

I think the tab actually charges through USB although the notifacation tells you not charging. You'll see the percentage of battery increments slowly.
I have a 4 USB wall charger with an output of DC5.0v 2100mA.
When I connect it detect as a USB connection and no charge.

Don't believe everything it tells you. Its pulling 500mA from the charger. That's enough to charge the tablet if its not being used.

Had the same issue with Tab 8.9. I have a 2012 Wrangler, with a built in USB port, also have a USB charger plugged into the power port. When I connect my 7.7, all I get is a red X over the battery icon. In the settings under status, it says "discharging".i have no issues with my Note2 using the same ports. Have tried different cables with the tab.
Any body have any ideas? The tab is stock, unrooted, running ICS.
The Samsung Galaxy Tab 7.7 being a tablet needs a 2A charger to charge, most smartphones need only 1A some even less

My USB charger is a 2 Amp, but is dual port. Could have sworn the package said it was 2 amps per port, unless both ports were used, then would be 1amp per port. Then my other is 2.5 Micro USB, BUT has a USB port in it as well.
The P6800 is picky for what charger you use. I got several chargers and tabs and phones. 2 of those are very picky, the 7.7 and the HP-touchpad.
Just get a real Samsung car charger and you will be ok.
maybe the thing (tab) needs to be powered) OFF before it will charge in your car's USB charge port...
I know at home with the USB plugged into the laptop.. it will NOT charge,,,...unless I power it OFF.. then it will charge...

I'll give that a shot, although would be pointless. Can't use gps, data or phone if it's off. I haven't bought the OEM charger for it yet.

Hi,
I spent a lot of time searching for good charger (bought at least 4) different types, and got allways the same results the red X until few days ago. I tried my Samsung I9100 phone cable (micro USB) with an adpter (P1000) bought from eBay (http://www.ebay.com/itm/Micro-USB-3...Readers_USB_Host_Adapters&hash=item484f20b751) for almost nothing. The result was impressive, on on hour drive the device charges at a rate of 10% progress (without having the red X).
Some thing else that may interst some of questioning the charge from the laptop, I had the same fantastic result (but the adapter does not allow Sync).
Cheers

I need an extra USB cable for charging my N4 in my car because I use a Scosche dual USB charger 2.1 amp. Will any USB cable be fine like the one in the link below or should I be looking for anything specific? I don't want something to mess up my N4 battery.

I was wondering the same thing. I'd like to get a couple extra USB wall chargers and micro USB cables to go with them. I'd like it to be as efficient and safe as possible for my Nexus 4 as well as friends that may need a charger. (N4 taking priority here)

Well as long as the power supplied is 5V (the usb standard) and under 1.2 amp (the output of the factory wall adaptor) you should be safe not burning out your phone. If you are just asking about a usb to micro usb cable then it shouldn't matter since the cable should supply the right voltage anyways.

The phone will only take the amps that it needs. I would get a 2A+ charger to be on the safe side.

I love the OEM USB Cable, especially cause it fits with all of my cases.
I would love to get the OEM charger, but after my current one acting up (usb wire for some reason keeps making it say usb charging despite being plugged into wall outlet), I'm cautious.

This is one of the reasons I bought the oem charger. Had the ac/usb issue. Changed wires and still does that. Used my gnex charger and it didn't give me problems. So I said it must be the charger itself. Bought the new one and now I'm confident when plugging my phone in. No more issues on the ac/usb charging thing

Hmm... for me, I changed the wires and it works. I think I would rather just save the $10 and put it towards the "wheneveritisreleased" Wireless Charging Orb.....or the TYLT VU when it comes out in April.
Hi guys, I have a few micro USB chargers lying around. Just wondering if using these would harm my N4:

The 12 V 500mA charger makes my phone's screen go haywire (applications opening and closing by themselves) but it does charge the phone.

at least you narrowed it down fast to the wire. in my case after swapping just the wires it was still the same. then when i used the original n4 charger on my gnex, my gnex suddenly had the ac/usb charging issue. my problem with not getting another charger was i sometimes charge both phones at the same time so i needed one more. good thing a couple of searches led me to the buychina site and now all works well.
I am very interested in this topic as I believe I'm going to need a new USB > MicroUSB cable. My cat accidentally knocked off my N4 while it was charging using the original cable/charger. While it seems the charger itself is okay, the cable is what I am worried about. The end seems slightly bent and, while it will plug into the N4 (which will report charging) it doesn't go as "easily". From visual inspection I think the problem is with the cable's microUSB end; I really hope that the N4's socket itself is not bent/damaged in anyway, but I cannot see any visual signs thereof.
I was really hoping to pick up another OEM charging kit, but it appears that (assuming they are legit ) that one can only find them on Taobao/ChinaBuy as linked above? I was hoping Amazon would have them. With this in mind, will there be anything specific to look for finding another "USB to MicroUSB cable" from Amazon to use with the existing, undamaged OEM charger? Thanks.
I'm no expert but I believe there shouldn't be any issue of you get a different cable. I've used an HTC, Samsung and Asus calls with the LG charger and there aren't any issues. If it's just the cable you need, go with Amazon. It'll be faster

Great, thanks. It seems logical that all "USB A > MicroUSB B" cables should be capable of the same thing, but I just wanted to be sure I wasn't missing something that would say, impair my ability to use this cable for not only charging with the OEM wall charger, but charging from my PC's USB ports, connecting to said PC via USB Debugging for rooting/flashing etc...

DUDE!!!! The 12V charger can KILL your phone.. The phone is designed for 5volts..
As long as the charger supplies 5 volts it is okay... even a 10 amp charger will work fine (if availiable ).. The current is controlled by the device (nexus 4 in this case).. It will draw how much current it requires.. Voltage on the other hand is decided by the charger.... 12volts will fry the device...

Oops, thanks for this heads up! I've used the 12V charger for weeks without any noticeable damage (though the screen goes haywire when it is plugged in). I'll switch to the original N4 charger now.
I tried the cord that came with the tablet, and my other USB cables - same results with all. My Note Pro won't charge via USB at all - when I plug it in battery status says "not charging" and it keeps discharging, while idling with screen off. Only AC adapter works and battery status changes to "charging". Any ideas?
You can't charge the tablet off s usb port. Draws too much current. Some motherboards have an option to turn on a special charging function for a usb port, but if you had that you would probably know.
Your stuck with the wall charger.

Stock kernel on the Xperia Tab Z must have USB charging enabled. This is an exception rather than a norm I would think, with OEMs probably choosing to disable this as a safety measure (or so i've read).
Until a custom kernel is developed for the Note Pro we'll probably not see charging over USB.
The problem is still the max output from the USB port, which is 5V 0.5A , you'll notice that the charger for the this tablet is 5.3V 2A.
I'm an electrical engineer not a computer engineer, so I'm not sure how a kernel would change the max output current supplied by the PC. This has actually piqued my interest, I'm going to do some tests and see how much current the port can push. I'm betting the data lines on the plug send some information about what's being charged.
Maybe I'll build an adapter that that let's the tab pull a full 2A from the port.

Does it make a difference if it's USB 2.0 or USB 3.0 port?
Normal USB 2.0 is 500mv, USB 3.0 is 900mv. Some motherboards can push this up to 2000mv, usually a red usb port

The nature of my kernel comment stems from my Nexus 4 experience with a custom kernel which has a setting to enable usb fast charge (Franco kernel with his FKU application).

This review says Note Pro 12.2 can be charged via USB - it's just slow. As I mentioned in the OP - when I plug it in via USB cable the battery status says "not charging" - could it be it's actually charging, but due to low current the device itself doesn't recognize it's being charged?
Just plug it in for a few hours and see if it increased your battery level... done.

It kinda works - with tablet completely idle and screen off it charged about 4% in 1.5 hours via USB 3.0....don't think that's helpful to anybody. Hopefully, someone finds a way to push more current through USB 3.0 port. Would be nice to eliminate the need to use AC charger.
I had mine hooked up to my laptop (Asus N76VB), it didn't charge according to the indicators (neither do my TabPro 8.4, Tab 3 and Tab 2, nor my TF700T), but the battery didn't drain either while I was using it. It stayed at 56% for 5 hours whilst browsing, which it really wouldn't do normally. USB 3.0, no additional settings enabled on the laptop, all Sync and GPS turned off on the tablet.
My TF700T literally said in the manual: "Charging from USB can only be done with the device turned off." I'm sure that applies to these tablets as well.
On the upside, my 15600mAh aSolar powerpack charges the device! :victory: (It can't charge my Tab 2 or TF700). I'm really, really pleased about that!
