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.

Every time i have tried another charger other than the hp one I get a please conneect hp charger message.
I haven't had much luck using anything else other than the charger that came with the touchpad.
Edit: just checked the specs on the adapter. Output is 5.3v, 2amps.

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.

Hi all
Long time Android addict and just got myself a transformer at the weekend. I have been puzzling the best way to charge it in car (read the threads on the subject) when I happened to wander in to Asda and spotted a mini 75W 12-230v power inverter on sale reduced from £20 to £5!. They are exactly the same as ones that sell on Ebay for 2-4 times that price out of Hongkong e.g.
12V to Mains 75w Car Van Mini Power Inverter Adaptor | eBay
I bought one and tried it on the way home from the store with the Asus AC charger and the transformer and it worked perfectly.
As a bonus it has a usb port built in not only rated at 1000ma but wired to be recognised as an AC charger (many arn't) which means it will do full speed charging on an android phone. So it should supply enough current to charge my HTC Desire even when using it as a satnav (many don’t). The only downside is that the flange on the Asus mains charger covers the edge of the USB port on the inverter so you cannot use both the AC and the USB at the same time without trimming the flange on the Asus a little.
Anyway I thought this was too good a deal not to share it with you guys.

The ASUS AC charger is normally working very close to it's limits when running off fairly stable AC mains. Running off this modified sine wave poorly regulated device may be enough to push it past its limits. If you want a good mobile solution that you can use for the TF and other small DC devices, search for the thread by Devcake where he lists options and actual reviews.

Does your TF indicate charging, e.g. with Dual Battery Widget, using this bullet charger?
E.g. If it outputs 11V-12V it should indicate charging on the TF, but if less than 11V, say 5V-10V, it would trickle charge only (no indicator).
I got one from same guy, and it does not work. I measured 2.8V output.

Mine arrived today. I hooked it up to 12v and tested the pins, got 2.8v. Then plugged i transformer and waited about 20 seconds. The transformer said it was charging on AC. I havent checked to see how quickly it was charging, but it gave the charging indication with the screen on.
EDIT: Tried it on another vehicle and now won't charge. Weird!
Any update to this working?

I use this one for my phone (HTC Desire HD). It should also be okay for the Transformer, right?

This one arrived today, there is one small issue with it, when you first plug it in the lighter the blue light gets bright and the asus orange light goes on and eventually green showing also the charging symbol, but if you unplug the cable from the charger and plug back in, it wont work, you have to unplug the charger from the lighter and plug back in. weird...

sorry, I don't think it will work.. the transformer needs 15V to charge, that one only is a 5V charger. i'd cancel my order.
OK, let's go over this again. The TF will charge with 5V at 1.5 amp but take forever to do so. The amps has nothing to do with it. It is the volts. If you feed the TF with 11V to 15V at 1.5 amp's or more it goes into the fast charge mode and charges in about 2 hrs. Anything that says 5V will charge the TF if you have several days to wait. If you have just hours you must charge using 11 to 15 volts at 1.5 amp or more to charge with. This is what the original power supply is doing. Please look at the specifications printed on the original charging brick. Note that it has dual outputs 5V and 15V if you plug your phone into the ASUS charger the charger is smart enough to know not to output 15V however when you plug in the TF the charger outputs 15V to charge the TF in the speedy mode.
Please read over "Dvecakes" thread for even more details and items you can use to charge the TF on the go and at home.
Hope this helps.

Has anyone by chance tried this car charger?

Also Does anyone have one of these replacement cables? I think I would probably order one directly from Asus though instead of trying to save a couple of bucks.

I want to put together a car charger to just leave in the car.
Has anyone else had this problem? I plug my Photon into a USB power adapter plugged into my car's cigarette lighter and the phone displays the message that the device is charging but the percent of charge continues to decline. I have changed USB adapters and USB cables but it still happens. If I use an AC adapter and the same USB cable the phone charges correctly.
Is it a software or hardware problem? I was unlocked and rooted using several of the current custom ROMs and the charging process in the car worked then. When I re-locked and went back to stock and re-rooted then this happened.
i am having the same issue as of yesterday. Did you ever find out what the issue was?
im guessing that the car was off and that it was a foreign car...
Numerous issue could actually cause the same symptoms, Apps/games in the background... failing alternator, failing cigarette lighter, failing car adapter...
car not running while its charging could also cause this issue depending on charge level of the battery and the volts of the battery...
What you'll need to do is eliminate the possibilities..
Try with the car on and the phone on...
try with the car on and the phone off...
try with a different adapter for the car...
try with a different usb cord...
try with a magnum 44 aimed at it...
Try with a different Car is also another good option.
Ditto.
I am having the same problem.....worked fine before I unlocked/rooted. Anyone else have a suggestion?
I have the same issue with the incar charger and using a computers usb port to charge my phone..(doesnt charge when under load ..ie-dowloading something)...i think that it is the charger being underpowered..example..
Stock a/c charger puts out 850mA
Most computer usb and standard car usb chargers only put out around 500mA
Sent from my MB855 using xda premium
Mine charges very slowly in the car. The other day, I plugged in at 32%. Drove 30 minutes to get home, and it had only reached 37%. Plugged in at home, and within 10 minutes had well over 50%, even though I was actively using it then.
This is on stock rooted, btw.
The stock drivers must use a very conservative power draw when plugged into a relatively low-output power source. By contrast, the power draw from a high-output AC adapter must be quite aggressive, because it charges more quickly than other phones I've used when plugged into AC.
It did turn out to be caused by the car charger being underpowered. I went to BestBuy and bought a "high capacity" charger and all is good!

The Photon needs at least 850mA charger to get charge currently. Otherwise it charge slowly or not charge at all.

It's at 25%... plugged it in. It wouldn't charge. I left it there for a while and it got to 26%... now it's stopped charging. Already checked the wall charger. I'm at work and I'm using one of the Galaxy Tab chargers. It shouldn't make a difference.
I would check the cord. For whatever reason my HP touchpads original cord wouldn't charge reliably, I change my cord out with my LG thrill and the HP cord will reliably charge my thrill and my thrills cord will reliably charge my touchpad, I can't really make sense of it, but that's how it worked for me. But I would suggest using the hp's wall plug in at all times due to the fact that it uses the correct voltage to charge and another's could destroy your battery.

I second this. I had to replace my cord after a while as well. I find that this happens over time with all micro-USB connectors, they just sort of lose their ability to snugly connect / the contacts wear out... Maybe it's just because I use my devices while tethered to the power strip sometimes, and the connector wiggles around.
Any charger that is not at least rated at 2mA and is correctly wired internaly will not give optimum charging current.
Stick to the HP original chargers or one that has been properly modded to do the job.

You want 2000mA, or 2A. I don't know the specs on the galaxy tab charger but I know the voltage is different too. The TouchPad is 5.3v, most chargers are 5v, and I have read on other forums that the voltage is more likely to be the issue, even is the charger you are using puts out enough amperage.

My mistake 2mA should have read 2A!
It's unlikely that any power supply will be exactly the stated voltage due to component tolerances, but I doubt that a .3v variance will make any difference. I've read what others have said, but never experienced any probs in reality.
All ratings are usually nominal values and set within tolerances. Under voltage would be a bigger negative factor.
Hi all,
When I use the charger that came with the HTC One my phone charges great, rapid.
But when I use any other charger that I have in my home/office it charges very slow. Even with a 2.1 amp charger!
The charger that comes with the phone has an output of 1 amp.
I've tried multiple other chargers (1 amp and 2.1 amp) and they all trickle charge.
Anyone else noticing this?
Thanks
Joe
I'm using old charges at home and in the office and it did seems slow but had not heard of rapid charge. Will the phone indicate this rapid charge mode? If not, is it real?
I'm getting slow charging even on the stock HTC charger. Not sure how I can enable this rapid charge cause 4+ hours from 0-1% to full is a bit ridiculous.
use orginal charger is best , maybe it has some relationship with your battery life
If anyone is coming from phones with smaller batteries, remember the larger the capacity the long it takes to charge.
I use the cable and charger from my Nexus 7 and it charges fast. Off my USB it is slow.
Real AC chargers have two pins shorted. You can hack a USB to micro USB cable and short the same two pins to enable AC charging with any adapter, wall, USB, or car. Should be pins 3+4, but don't hold me to that.

i've done exactly this, and damned if the One still refuses to draw more than ~500 ma off of anything but the 2.1 A wallwart it came with (i don't have any others to try with). i'm about to dig out an old inverter to see if that will actually work. wish i'd paid more attention to my EE dad when i lived at home; i've gotten a serious crash course in this stuff while trying to get my One to charge in my car, when it's on.
edit: so i got my old inverter out, and spent about 15 minutes testing. i used the 2.0A adapter that came with my Nexus 7 to test, as well as the 3.1A Mediabridge adapter i got here. my phone was at about 45% when i started testing. unplugged, Battery Monitor Widget reported a drain of anywhere between 500ma and 650ma (running Ingress, wifi on). plugged in to the Mediabridge adapter showed, at best, a drain of 50ma. the Nexus adapter plugged in to my inverter charged at a fairly consistent ~120ma. i didn't touch my phone the entire time.
i left my Nexus 7 at work so i can't use it to repeat the test, but i will do so tomorrow. the cable i'm using is this one. i'm not crazy about having a ridiculous DC-AC inverter in my car for my phone, but if that's what i have to do so it can be used and not drain, then so be it. admittedly, i don't really understand these things enough to explain these variations, but i plan on learning ASAP. perhaps somebody else can shed some light on why the device charges different, and how it identifies an AC-USB adapter vs a DC-USB adapter.

Math doesn't support what is happening though. Phone has a 2300mAh battery. The OEM charger outputs 1A (1000mAh)
At most, it should be around 3 hours for full charge, when in fact it is closer to 4-4.5 hours. It's the last 10% that is the issue, it will trickle charge to 100% rather than rapid charge.

Yes, I think that's exactly what the HTC does... I read a pretty good article recently about Li-Ion batteries that talks about how trickle charging is the best for battery life, and it wouldn't surprise me if HTC got a little aggressive the way the this phone charges since we can't swap the battery ourselves.
I'm trying one last car charger, which matches the wattage of my Nexus 7's 5Vdc/2A AC adapter (which I've had the best luck with, when charging the phone while in use): http://www.amazon.com/gp/product/B009TBF7IG/ref=oh_details_o00_s00_i00?ie=UTF8&psc=1
If that doesn't work, I'm going to put a 300W inverter in my car with the AC adapters themselves and stop buying stinking DC adapters. This phone clearly pays very close attention to the wattage available from whatever it's plugged in to.

Hi everyone,
I have just swapped my Galaxy S3 to a HTC One X+ because I couldn't stand Samsung's Touchwiz, and I love Sense 5. The downside is the charging times on this new phone are pretty laughable!
Now I know different cables can give different currents consistently, but I have three cables (one at work, one in car, one at home) that would all deliver 1000mA to my GS3 and I could go from 10% to 100% in about 90 minutes, about 1% per minute, it was great! Battery life on this phone never degraded so I know 1000mA wasn't damaging at all (all GS3s can take a maximum of 1A).
I've now moved over to the HOX+ and it's taking absolutely forever to charge, between 3-4 hours to charge from low. I simply can't wait this long, it's beyond a joke :crying: I've checked Better Battery Stats and my battery usage is about the same as my GS3 when unplugged (about 4-5% per hour) which is fine, so why the difference in charging times?
On my GS3 I had an app which showed me charging current that was specific to GS3s and was very reliable, but I can't seem to find a reliable app for the HOX+, the one I have is Battery Monitor Widget and it reckons I'm charging @ 330mA and I'm currently at 22%, that can't be right can it?
Here is what my phone is says when charging "Charging (USB)".
In the past hour it's done about 20%.

Erm thats the issue. When you charge using the AC (By cable to the electric socket) it says "Charging(AC)" . This usually takes me from 10-100% in about 90 minutes with the HOX+.
Somehow either you are connecting it to a usb hub (laptop or a computer) which is pretty slow compared to the AC, or your phone is mixing up the AC and USB currents. So an advice, use an electric socket and make sure it says "AC" in the power tab. IF so, check the charging time you should find it similar to that of Samsung.
I also think usb 3.0 is faster in charging than 2.0 ? If you are on a new pc with a new motherboard you should find your sockets 3.0, so don't use a usb hub especially if it says usb 2.0 since it will be pretty slow.
Hi Gand0ur, thanks for the advice.
I should have said before; I never charge via a computer/laptop/USB hub. Only directly into the wall. It is an aftermarket charger but it's a good quality one as it charged my GS3 @ 1A and also my old Sensation charged in about 90 mins.
I've just tried a different cable and still the same outcome. I'll try another wall plug when I get home tonight

Sorry.. I am kinda sleepy so I posted without saying any thing. Anyway I wanted to post a pic of the text on ny stock charger. Says the following : output: 5v ~ 1A .
I will post a picture when I wake up in a couple of hours.

No problem! The charger I am currently using is a 5V/2A (for tablets) and has worked fine for every phone previously, giving 1A current.

dont ever use after market charger even though it is for tablet or note samsung...i tried and it is prety damn slow...
so just use your htc/stock charger...it will be fast charge...2hr the most maybe less...

That isn't necessarily true. This charger has been the fastest thing to ever charge my HTC Sensation and GS3, and come to think of it my Nexus 7 charges faster with this charger too. As I said earlier, I had an app on the GS3 which showed it was outputting 1000mA (maximum the GS3 allows) and it would charge that phone in around 90 mins. According to the HOX+ app I have I'm only getting 330mA. Whilst I agree that poorer after-market chargers often give dubious results I'm confident that this isn't the charger's fault.
I'll try the a HTC charger when I get home, but the other night I had it on charge with the HTC charger and it didn't seem to move very quickly.
I'll just say what I know from experience with my HOX+: it only seems to be charging in a normal (and pretty fast) way with the original, from the box, charger.
I tried charging it with the charger from a Desire Z - slow; charger from Desire S - slow; a Nokia charger - slow.
I also noticed that while the Desire S or Z can get charged while being used, when using a car charger (a Nokia one), the HOX+ seems to be using more current, and it ultimately dies. It happened this summer, so this might be an issue.

I think you're right! I tried my wife's HTC One S charger last night (because the HOX+ doesn't come with one) and it changed to Charging (AC) for the first time. I have to say this is a massive let down for me, my car charger saved me so many times with my GS3 (for example I drove to Scotland and used GPS all the way, and the phone still charged right up at the same time) I'm not sure I can handle it not being able to cope with other chargers.
I find this extremely frustrating Is there not a hack to get around this with root?
I'm not sure about the Samsung, but the HTC will only go into the fast/AC Charging mode when it see the Data+ and Date- signals shorted on the USB port. This can be designed into the charger, such as the factory HTC wall charger, or you can buy "charging only" cables and then use any USB charger to get your HTC to go into AC charging mode. These charging only cables are tough to find, but amazon does sell them. Keep in mind that the charging only cables will not transfer data at Data+ and Data- are shorted. Once you are in AC charging mode, the phone takes over and determines how fast to charge. At low battery levels (less than 80% or so), the charging rate can be as high as 1000ma/h or the maximum the charger is rated to deliver. If the charger is rated to deliver more than 1000 ma/hr, the most your phone will draw is 1000 ma/hr.
Now there is another variable, the cable itself. Cheap cables sometimes have too much resistance to pass 1000ma/hr and can be the problem as well.
One other issue is the number of knock off chargers and cables out there. Beware of e_ay. You may not be getting what you think you are.
One final note, Apple designs the ipod to look for the Data+ and Data- signals to not be shorted (opposite of HTC and most android manufacturers). So chargers that are designed to charge Apple devices will need the Charging Only cables to charge android devices in the AC charging mode.
So if I didn't confuse myself, hopefully this will answering some charging questions. I've researched this and have tested many chargers and cables.
