Samsung Galaxy tab 8.9 car charger recommendations? - Galaxy Tab 8.9 Accessories

Hi everyone
I'm looking for a car charger that would actually charge my 8.9 tab.
I have hooked up my tab to various USB sockets and im still getting the red X on the battery. I even tried a 2.1a socket. No luck. This is going back to amazon unfortunately.
XTG (Does not charge my tab)

samsung galaxy tab 8.9 and XTG 2.1a car charger showing device is not receiving charge from the 2.1a usb charging port. XTG at fault?
samsung galaxy tab 8.9 and XTG 2.1a car charger on ac to dc bench test inverter. The XTG fails to charge while device is powered on. It will only charge when off. Even a standard USB port can do that.

So if anyone can recommend something that does work, please do let me know. Im trying to find something low profile instead of having to use a DC-> AC -> wall socket -> usb in the jeep. >_<

Here's UPDATE in case someone has the same issue with charging the 8.9 tab via usb.
With these steps followed, I was able to get USB charging from any usb socket. Not just wall.
I rooted my Galaxy 8.9 following these instructions:
http://forum.xda-developers.com/showthread.php?t=1287205
And then, I flashed this rom:
http://forum.xda-developers.com/showthread.php?t=1359068
After that, I flashed this Kernel:
http://forum.xda-developers.com/showthread.php?t=1323957
And then, I enabled USB charging as described in here:
http://forum.xda-developers.com/showthread.php?t=1323957
And DONE. Now its charging from USB.
It charges slow but that's expected. If i want to charge faster, I use the wall socket.

You were very close to getting it correct with your first post. That car charger you have is plenty powerful at 2.1a (I'd actually recommend getting one that does both 1a & 2a to charge either a phone or tablet in the car). My understanding of the Galaxy Tab is that they won't charge correctly over USB. By default, they just behave as mass storage devices. If you want to get your Galaxy Tab to charge over USB, you'll need a special USB adapter that connects inline with your existing charging cable. This little gem was designed for the earlier generation of Galaxy Tab, but the charging issue is the same.

Or, you could buy this nifty external battery, which includes the required inline charging cable.

Obviously, you were able to get it to work by rooting, etc. But for those who may be interested in a vanilla solution, this may help. Also, sorry for not posting links, but I'm a noob poster, and the rules don't allow me. You should be able to find the products I mentioned above pretty easily though.

Looking for USB Car Cigarette Lighter Adapter

I have had about 5-6 of these.. every one I get my hands on is junk. When using the GPS, with the phone pluged in (non stock cable) I still end up killing my battery dead. The second it comes off the charger is turns off.
Can anyone point me in the direction of one that charges correctly?
Thx in advance!
I use my wife's from Verizon and it seems to work ok. It has a USB port so I can use my normal, thick data cord. You're probably running into ones where the cord is too thin to give proper charge. This one works great with the data cord.
I have the Samsung car dock. It seems to do fine with just GPS. I don't think the Epic can draw enough current to maintain it's charge if you're using any other features. If I'm running GPS + Streaming Music, it will discharge eventually and become very hot.
You need
1. a reasonable quality USB charging cable so that the Epic will draw the maximum current, or a power adapter that grounds the data pins. If the epic thinks it's connected to a computer it won't draw the maximum current.
2. an adapter that will provide 600ma+. I used the one from Griffin until it broke* and I bought the Samsung cradle. http://www.google.com/products/catalog?q=usb+car+power+adapter&hl=en&um=1&ie=UTF-8&tbm=shop&cid=1150301903319147928&sa=X&ei=4h0ZTtSyL4aDgAeA7rH0Dw&ved=0CIUBEPMCMAE
Hope this helps.
*Griffin agreed to fix it, but it's been several weeks since I sent it in. I'm a little unhappy with them at the moment, but the adapter was fine until it broke, maybe you'll have better luck.

seems like a good price. i ordered 3 single usb 1 amp units for 1.99. I'll give feedback once there in my hands.
sounds weird but goto radioshack or wherever & get one for a palm pre it works great charges really fast to, try & get palm brand because thats what im usin
Not as strange as you might think. As the pre/pixi charger is 1amp allowing it to power the touchstone with enough current. Most
12v lighter plug USB adapters are .5amps.
Also the pre/pixi lighter plug charger requires the cable that comes with it. And although it is a micro usb the end that goes in the lighter plug is not standard its thinned and narrower.
+1 on the pre charger... been using one since I had the pre, and it is awesome. phone still discharges when streaming pandora and running GPS, but GPS by itself results in a very slow net charge on my drive to work.
We sell a case logic brand charger at work for 15 bucks that is rated at 800mA, used it a few times and know a few people that have one. I'm sure online price is cheaper.

ive never had that problem mine always charges no matter what
I get mine off of EBay. Just make sure its output is 1amp.
USB and DATA cable
That's because if you use a USB adapter and a DATA cable the phone only charges at half it's rating. This is because it thinks it's pulling the power from a computer USB port and it doesn't want to overload (and fry) the port.
I picked up one of these, opened it up and soldered the two middle USB pins together. Now it allows my phone to charge with a data cable at it's max rate.

there are pretty sweet power inverters that run 30ams, so you can plug in laptops and such. pretty compact, AND they come with 2 usb charging ports.
there under 50 bux.
I use a j-lo brand car charger. Its for a gps and charges @ 1000mah. I also have a power inverter, the cheap one from walmart with 2 ac outlets and 1 usb port. Both of these work very well.

2.1 amp car charger question

Bought a dual charger for the car, has 1 amp and 2.1 for devices like tables. When I plug the Tab Plus in the tablet gives me an X for charging and doesn't charge. Tried different cables. Any ideas??? GT 6210
Not compatible mHa...
Sent from my GT-P6210 using Tapatalk
So only Samsung OEM car and wall chargers work??? I even trid a lower amp charger in the house figuring it would just take longer to charger, and still get the X if it's not the Samsung wall charger.
2.1a is plenty to charge it, but as you said, only Samsung chargers will do it. It is highly annoying.

Interesting to note:
When the Tab/Tab+ is connected to an HDMI adapter (either dongle or stand version: I have both) the tab will draw power from ANY USB source and show it as charging. A generic 2.1 amp charger will add to the battery even while playing MAME on my HDTV using a BT PS3 controller while WIFI is enabled (a 500mA charger works too but cant keep up....in other words it will deplete your battery...just slower). The same generic charger will NOT charge my Tab+ when NOT connected to the HDTV/HDMI adapter.
It's charging, but it's only pulling 450mA. This is a safety measure to prevent pulling too much current from a computer USB port.
This is nuts. If it charges through an HDMI cable??It charges slowly through a computer??? I'm surprised nobody has come out with a "charge only" cable so it works generically. Obviously some of the pins can be left off or crossed to trick it.
I'd buy 3 and keep them all over the place!
I've seem them for Apple,I devices, even was shipped one by accident for my Ipod.
I'm writing CableJive! Maybe if they hear from enough of us they support out product. '[email protected]'
Eureka! I grabbed an old USB version 1 extension cable (female to Male) and plugged it on the end of my Tab sync power cable. Plugged it into Tab OEM wall charger, worked fine. Then I plugged it into a generic wall charger for phones (1amp) and IT IS CHARGING!
Still won't work on car adapter, tried 1 amp, 2.1amp, and 2.2 amp.
Ordered USB 2 extensions to test.
Have you made sure that the plug will charge something else? Make sure it will charge your phone or something. I know those dual micro-chargers have to be pushed with a lot more force than you would think. I would also check both ports on the dual charger. Usually only one of the ports will output 2.1 amps while the other only outputs 1 amp.
Quick semi-related charger question: are all Samsung Tab chargers the same? Or, at least, are they cross-compatible for charging?
I've got an imported tablet, and it's charging very slowly with a UK adaptor (which was supplied by the import company... had been expecting more, I have to say).
If I tool up and go shopping for a genuine Samsung Galaxy Tab charger, will any of them do, or do I need to be specific? Does anyone know?
i got one of these handy.

i bought it from DX few months back. http://dx.com/p/usb-power-adapter-for-samsung-p1000-81753?item=1
and it charges my fone with any usb chargers i have.. i also use it for my 2.1A car charger and works as expected.
I second the adapter recommendation shown above. I just wish it had some way to tie it to the cable so it doesn't get misplaced. They're pretty cheap, though, so I bought a couple extra.

here's mine..its tied with my extra sync cable.. these adapters are fragile and one of the plastic clips broke.. secured it with a zip tie and now even when i dropped it several times the white case stays secure.. i bring it with me all the time...
Have you guys tried these adapters both on AC and Car 2.1amps WITH the Tab? The references I see above are for phone.
Oops...never mind, went to sight and saw a reviewer listed Tabs.

Car charging problem - not being charged

Hey, I don't know how to force to charge tablet in the car.
I use 2.1 amper car charger. After I plugged it to the tablet I got either red cross or just info that tab has been connected.
I know trick to mount USB partially, sometimes it works and there is no red cross, however I noticed in Battery Monitor Pro:

You see tab's been plugged, it shows "USB connected" and "Discharging" however power depreciation is still high.
When there is no red cross (I mount USB stick partially). Then charge rate is very low - 0.5-0.6 ampers instead of 2.1.
Charger is working good, I tested it.
How to force it to be charged at full rate? I worry about GPS power consumption - Sygic+Locus Pro = more than 1 amper depreciation, so this is matter of time till tablet will go off. The worst scenario... during road trip.
You need something like this with 2.1 amp

Or this Belkin one
http://www.belkin.com/us/p/P-F8M114
Or the oem Samsung for the galaxy tab, which should also Work with tab 2

Thx, but are you sure that Dual USB charger will give me full 2.1 amper (or min 1A)? I have 2.1 A charger but it gives only about 500-600 mA. I've heard due to USB cable pins made for Apple products (even if it is universal one).

I just played around with making a wireless charger. It is 1 amp and it will charge the 7" tab2. My 850 mah wall charger will charge it as we'll. both show an x over the battery but they charge. The secret is the data wires. They need to be connected together. I modified a cable for a car one time to do this, but many car chargers today do it for you.
The tab 2 will charge off less as it can charge off a pc USB port at only 500mah, so it is not the amps.
Possible solution for chargeing issue

Pardon me but but you have a Samsung Galaxy tab 7 plus looking at your other posts. My P6200 only charges from 0.9A lower limit to 2.02A upper limit at 5vDC if your amps go lower or higher you get that red cross
I get best results at 2.0Amp charge and no more. otherwise battery only takes in 0.5 to 0.6A which I see you observed the same with battery pro I did it with a external power supply that reads drawn current
P.S I know I am late hope it helps somebody else

[Q] Charging problem (micro usb)

Hello,
I have a Moto G 16Gb version from amazon.fr. Now I have a problem with charging the device. There was a charger from motorola in the package (a White one) that works without any problem.
Here at home I have another micro usb charger from my Samsung Galaxy S3 / A tablet / chinese phone / and from a Raspberry pi. All these chargers don't work on the Moto G... Is there any difference? I thought that Micro USB was a Standard worldwide ?
Think I found something. The chargers that doesn't work are chargers with an output of 1000mA. Then I took a charger (with the same USB cable) with an output of 500mA and it works. So all chargers with 1000mA are worthless with this phone I think.
I use a charger with 1000 mA and it works...
Support says it's best to use a branded charger as the charger needs to fulfill certain specifications to be able to work. But you used a Samsung charger anyway - maybe it's an issue with the phone?

The higher rating has no bearing on the charge delivered, the device will charge at an appropriate rate.
True, tried my car charger (2A) and it worked.
But it doesn't work with my Raspberry Pi charger, Jiayu charger, ...
So I have to buy a different brand of charger I think. But it remains strange. So, If I am by a friend, and I want to charge my phone and he has a different brand of charger ...

Correct ! My opinion that a 1000mA doesn't work is not true. But it can be that brand X works and brand Y doens't work. That's my conclusion so far

Noob asks: What is POGO and the Samsung Xcover Pro

POGO: I have Googled but cannot determine if it is a generalized interface type, a standardized proprietary plug/jack, an clever acronym, who knows. Would some kind soul point me at a tutorial?
Samsung Xcover Pro: Because I want a rugged smartphone with a removable battery and no bloatware, I got one of them. It's common else where, but not in the US. It's been my smartphone experience that one of the smartphone weak spots is the connection, which gets plugged and unplugged so many times, is around and collects crud...and when it fails, you are SOL. This phone has a POGO plug. Is there a USB to POGO cable for this phone? Since the US market presence is so small, you cannot even buy the replaceable battery, you have to get it shipped from Europe. Gamber-Johnson makes a nice cradle with a POGO connection for this phone, for a mere <gasp> $150
I know, I know, I am a masochist who always takes the path of greatest resistance (to say nothing of impedance and reluctance).
Maybe the simplest thing would be to get a magnetic USB-C cable to preserve the socket on the phone.
It's called a POGO because of the gold-plated pins. They are spring-loaded like a pogo stick. They are used in applications where a drop-in cradle provides support for the device that's to be charged.

I have purchased a Samsung Xcover6 Pro and I'm also looking at 3D printing a dock. Did you or anyone else find any electrical details of the POGO pins? Can we just apply voltage to the pins (in which polarity?) or is there a communications protocol required to enable charging?
Apologies everyone. I didn't think to check Thingiverse. There's a design here and it appears to accept voltage with VCC left and GND right.
XCover Pro Pogo Charger by xnappo
Remixed from @julvr's excellent work for XCover Pro. I used these pogo pins:https://www.amazon.com/gp/product/B07FQ52W88/ref=ppx_yo_dt_b_asin_title_o09_s00?ie=UTF8&psc=1 (and I have a lot of them so....) 9V is needed for Quick Charging - could support higher but 9V should be safe for now. Once...

Good find! I ended up buying a commercial unit from KOAMTAC. It was expensive but I do not regret it after more than a year of use. The charger for a spare battery was a plus.
https://www.amazon.com/KOAMTAC-1-Slot-Charging-Cradle-XCover/dp/B084KXP3BP
EDIT: oops..never mind...just realized I was looking at a different phone model..I'm a tool, lol.
I can report that I have designed and printed a cradle for my Xcover 6 Pro but the tolerences are very tight and it requires fiddling with the position of the phone to get it to work. I initially used a bench power supply which resulted in good charging speed but I connected to the positive and negative of an old broken (phone end) USB lead and I am getting slow charging speed from a USB charger. I assume that some circuit is required on the data pins to enable high current on a USB outlet. I have tried several USB power supplies.
EDIT: I have replaced the USB cable with a 5V 3.5A PSU (non USB) and AccuBattery is reporting ~6.5W charging speed.
I can also confirm that there is no increase in charging speed between 9V and 12V and charging shuts down at 12V.
Typical way of enabling fast charging is to short the USB data pins together, but this maxes at 1.5amps by USB spec, or 7.5 watts. Beyond that you're getting in to data signals to negotiate higher charge rates.
A fairly decent explanation is here - https://microchipdeveloper.com/usb:bc12
