I screwed up mine. Short of ordering one from HP i wanna know if someone has had any luck in getting unofficial chargers working with the touchpad.

Yeah...I use my gnex USB cord/charger on the round plug in base. Other USB cords will work so long as you use the touchpad plug in core. Hope this helps. Tc

Actually you can use a different base as well. I use my HTC one and it works perfectly although it charges slower. But an unofficial one should be good.
Grr...I can't post links...
I ordered a new charger off ebay for $3.50 shipped, just came in today. Worked like a charm. My cellphone charger (Nexus S) wouldn't charge it.
I haven't used this bad boy in like 2 months, almost forgot about it!
one thing for sure try to charge it under android. even blackberry charger works(smaller mAh) only its slower to charge
my asus transformer charger works with a regular micro usb cable.
That official TP charger is 2000ma, cell chargers do work but are only around 750ma. The touchpad can draw about 850 when in use. As such, you will want something over 1000ma if you want to use it and have it charge.

thanks a lot guys. The Samsung Galaxy Tab's charger is almost the same as the HP touchpad's charger (almost the same wattage; 2000mAh and 5V)
I am hoping it will work just as well.
The problem is that when i connect any third party charger to my touchpad it says use only HP touchpad charger and doesnt charge

Yes I have read this many times but the TP under CM9 charges better then under WEBOS
I can check if my spare Barnes & nobles nook charger works with the tp. (1900mah and 5v if I remember correctly).
If so I could ship it to you for free as I have no use for it.

my tablet ran out of battery and then my charger screwed up.
the puzzling thing is that now that its completely drained it does not accept other chargers. I know it does when its still running because i have used different ones to charge it while it was running but when its completely out it only wakes up if i connect it to an official TP charger
Any charger will work via cm9, but on WebOS it will detect that it isn't the stock charger.

In about two hours of charging I went from 8% to 41%. Is anyone else experienceing this issue? I'm using all the cords and plugs given to me for the wall.
I don't have the SGS3 (yet), but my guess is that the battery is so large it takes longer to charge. Keep in mind that it's a 2100MaH battery. Depending on the power that the charger puts out, it could take longer to charge this battery than another phone.
Mine charges fairly quick with stock items.

I agree, the first few cycles might not be too accurate. If you want a faster charger get the HP Touchpad charger, it has 2 amps where as the Samsung one is .75 amps of charging. only $5 on hp website. that's what I use.

Monoprice sells a 2.1 amp 4 usb wall charger as well but it is not as cheap nor do they have free shipping *although atleast in CA I can get a flat rate of 25lbs and under for ~$5 shipping.*
I'm surprised no one has posted the correct answer to this yet. The wall charger Samsung has decided to include with the S3 NA is complete and utter crap. I believe it is .15amp draw. You need to immediately throw it in the trash and buy a new one. It is not a problem with your phone.

My Samsung Charger that came with the phone is 1Amp...charges the device fine. I don't think the 2Amps will make a difference if the charging chip doesn't support it (not saying it doesn't but the SGSII would only charge at 650maH no matter what charger you put it on)
Mine's charging insanely fast with the stock cable. Not sure if it's a good thing because battery life isn't all that amazing on my phone so far.

doesn't that mean each USB port is 0.5 amps?
Anyways if I'm not wrong the amps has to do with what it can supply. Whether the device tries to draw that much power is up to the device.
The stock charger is 5V 1amp.
Even if you use a 2 amp charger it will likely only draw one amp.
Even if it does draw 2 amps that would mean you are increasing the heat associated with more current. Heat is the worst thing for battery life. Its always better to do slow charge unless you're in a hurry. Your battery will last a lot longer that way. Having said that, I think 1 amp is a good compromise for speed and heat.
p.s. computers output 0.5amps per USB slot by default specifications.

A lot of chargers will be rated less than the stock charger. Especially cheap car chargers. In that case the phone can only draw at the charger rating.

The values listed on the charger is the max output it can provide. If the setting on the phone or the hardware is set up to only pull 1A, then it will always pull that unless that is more than what the charger can provide.
That being said, you should be able to take the battery out and charge it faster separate from the phone. I've always read, though, that charging a battery faster ( i.e. turning up the current) will/may reduce the life of the battery

I have a Touchpad charger and it can be used, though I noticed that the phone got hotter than normal, IMO. The phone comes with a 1.0A combo wall charger with USB cable. Interestingly the Samsung stand and battery charger that comes with the spare battery comes with a .7A charger but the charging unit itself is 500mA/1A on the input with output at only 4.2v @ 450/900mA.
Couldn't find where anyone posted this, especially since search is broken right now.
I have been searching for a good car charger, and have tested several from Monoprice, which ALL eventually quit charging. Finally found this car charger that works perfectly. It is the only charger (that I have used) that can charge my phone faster than the Waze app can drain it. Excellent quality quick charger for $5. I believe it is rated at 950mA. The others were rated at 1A, but evidently that wasn't really the case.

FYI - The charging cable is attached, so it is not a removable micro USB cable. Surely you can tell that from the picture. The clear plastic Motorola emblem glows blue when plugged in, which I thought looked cool (or, "looked chill" for you kiddos ).

I have one works great.
That is a very widely used car charger and pretty well loved. Personally I use a http://www.monoprice.com/products/p...=10826&cs_id=1082603&p_id=8858&seq=1&format=2 with a USB cable. Have never had any issues with it dying or failing. It also barely sticks out of my cigarette lighter. Any all in one plug I've ever used has always had a lot of bulk.
I use the Zagg Sparq. In the car and work and such. Little pricey but it's got a lifetime warranty.

While we were on our way to key west last week also, we killed 2 count them 2 of the griffin 2 port stubby ones. They worked at first, then died. Heat probably an exascerbating issue in that case as we were in a miata with the top down and the sun on that all black interior for 8 hours. Also, had both my phone with nav and ambling books and bluetooth, and my gf's iphone 4 and her taking pics non stop haha.
Anyways I found at radio shack a stubby iGo 2 port 2.1 amp that worked without a problem the rest of the vacation doing the same heavy load in the same heat for untold hours from key west to ocala on the way back to my parents place at the end. It was more like $30 than $3 though!

Recently I traded my galaxy nexus for a galaxy tab 10.1. But whenever I plug it into a computer or an outlet there's a red x on the battery... it charges reallllly slow. I left it to charge for nine hours from an outlet while turned off, and it went from 5% to 55%. WOW. That's really slow. So I thought that the problem is the cable so I bought a new cable that came with a car adapter. And it worked like a charm in the car. However when I traded I kept the 3 pronged galaxy nexus charger. So anyways I arrived home happy, but I wanted to test it in the computer... Red x again. I tried the wall outlet, again with the x. I tried the wall outlet with 110v and 220v still red x. Then I looked at both outputs on the wall charger and car charger both had the same output which is 5volts and 1A. Then I looked at the input and the car charger was 12-24VDC and the wall outlet was 100-240v and 50Hz and 0.15A. I need help please.
I have 3.2 honeycomb and P7500.
I think that this is an internal issue software wise.
If you need anymore information don't hesitate to ask.

I get that if I try use galaxy nexus charger, however if I charge my galaxy nexus with the tab 10.1 charger I have no problems, make sure your using the correct charger, and for the slow charging I have a USB extension cable if I use that it can take up to 12 hours for a full charge
By charger do you mean cable or outlet?
Sent from my GT-P7500 using xda app-developers app
simplest answer is that the red X means that you're not supplying enough voltage to your tablet. You need 2A (A = Amps), computer USB ports generally do 500mA (1/4 of what you need). Phones usually need less. So the reason your tablet won't charge off the phone charger is because it doesn't supply enough voltage; the phone does fine on the tablet charger because it's just oversupplied (don't worry, your phone won't be damaged by this!)
So what you need is:
1) an original charger for this particular tablet (the cable probably isn't the issue, but I've seen cables that can't transmit the full voltage. The nook color is a good example of this)
2) a 2A charger - can't promise any particular ones work though...
3) (and this is the one you should do): You're on XDA. This is a place for folks who root and install custom ROMs on their devices. Most of the ROMs have USB charging built-in (in the Kernel; don't worry about what that means). Install a custom ROM (I'd suggest AOKP). Problem solved, plus you've increased both performance and functionality of your device exponentially. If you're not willing to do this, XDA probably isn't the place for you anyways.

I found a solution to a problem that was really vexxxxing me. One of my chargers was working and the other (longer lead) all of a sudden started showing the red cross. Ahhh. The solution (http://www.androidtablets.net/forum...galaxy-tab-10-1-not-charging-brand-new-3.html) was to blow very hard on the 30 pins of the charger and hey presto - started charging again without the red cross.
There are solutions to this problem with quite a few custom ROMs. Task's ICS for example has this patched. I am quite certain there are others.
I lost my HP charger last week, so I decided to charge my Touchpad with an el cheapo USB charger lying around my house. However, after charging it overnight with that charger, I could not turn on my Touchpad the following day. I then checked the specs of the charger and it has an AC input of 100-240 V and 50/60 Hz and a DC output of 5 plus minus 0.5 V and 500 plus minus 30 mA. I'm not familiar with electronics at all so I'm wondering if using a charger with different specs than the HP's one (input: 100-240 V, 50/60 Hz, 0.4 A; output: 5.3V, 2.0 A) have wrecked my Touchpad.
I tried to charge my Touchpad after finding my lost HP charger, both through direct micro-USB and through the Touchstone, but could not turn on the Touchpad after hours of charging in either route. I also tried various button configuration to turn it on (after looking at similar charging issue threads), but none worked as well.
I would really appreciate your help in helping me use the Touchpad again. Thank you in advance.
You really need to get the official one, it puts out so much more power than anything else. The TP is a hungry beast. The official was also rated as one of the best chargers period.
Mine died and a half-day on the official USB charge resurrected it.

I tried to charge it with the HP adapter but with a random USB cable (since I lost the old one). Do you think I should buy the original cable and try charging with it?
I've been charging the Touchpad for 2 days now with the original adapter and the HP Touchstone but it still hasn't turned on! :crying:
In theory using another charger shouldn't hurt anything, the Touchpad will charge slower because of the lower current output but nothing should go wrong. I always try to avoid cheap chargers because I haven't had the best experience with them in the past. Plus or minus 0.5V seems like quite a bit, a good charger will be able to provide a much more steady output.
Hopefully you can bring it back to life by charging it overnight with an official charger.

Yes I got that message too but I ignored it, thinking that it would just be slower to charge. Previous times the cheap adapters did trickle charge but for some reason for this charger the Touchpad did not turn on at all after I left it charging overnight.
Sounds like it died; with the screen on, my touchpad drains well over 500mA (more like 800). Therefore, leaving it overnight with the screen on and a 500mA charger would just drain the battery. I think you'll need to follow the dead touchpad recovery threads.
As for the charger breaking your TP, I charge my touchpad whenever wherever with whatever I can find. So I don't think the input matters much, and shouldn't ruin it. If the charger isn't at least 1000mA(1Amp), then I plug it in while turned on, then shut it down.

Yay! I got it charged after trying so many things posted here (angling the USB plug, put the tablet upside down so that the power button was pressed to complete discharge the tablet, charging via touchstone, etc.) but nothing worked. Finally caved and bought a new usb cable (I still had the HP adapter) on Ebay (http://www.ebay.com/itm/290794766792?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649). The moment I plugged in the new cable the home button flashed white and I was able to turn the table on.
I'm planning to sell the Touchpad after this since the tablet is just not stable/reliable enough for me.
