3rd party charger screwing with touch screen?

So I've got a bunch of these cheap ebay USB chargers. I was using them with my HTC Kaiser but now I have my desire - When the phone is on charge using one of these, the touch screen won't work properly. It goes crazy, registering its own "touches" so menus fly about, etc. and if I try touching it, it either doesn't register it, registers the touch about 10 times or in the wrong place!
As soon as I unplug, back to normal!
The HTC charger says output: DC 5v, 1amp
This charger says output: DC 5v+- 0.20v, DC500mA +- 30mA
Does this mean these chargers arent quite powerful enough or something? Could I be damaging my phone by using these? They do charge ok but seem to take longer than the HTC charger.

I had exactly the same problem with the G1 and after a fair amount of time researching that issue, I read, and was told that the voltage on many 3rd party charger are not as well regulated as on HTC charger's or pc's USB ports.
On my G1 the problem stayed even after unplugging the charger.
You'd be much better off with a genuine HTC charger or just using your pc's USB ports.

I have the same problem with my phone .. the problem still remained after unpluging and using my own charger.
Does it go away in some time? is your phone ok now?

Well, on my Dream, the problem wasn't constant, but it was there very often, it seem to occur less when I was swapping with some spare charged batteries.
On my Dream the trick was to turn the screen on and off, and it would work most of the time...
I suggest you try to charge of your computer, the voltage output is regulated properly and I was told several times that the opposite, i.e. cheap chargers, were messing with capacitance screens.
I have been charging my Desire with the HTC charger and my PC and haven't had any issues yet.
Better safe than sorry, I wouldn't have got an upgrade if my Dream didn't have that problem in the first place, and it quickly becomes a massive pain! Especially when you have no keyboard.

Problem didn't go away, so I sent my phone to the waranty service.
Using the original charger and original usb cable everything was ok, the problem appeared when I used an usb extender with my computer. First, windows didn't recognize my device, and then the touchscreen problem appeared.

I had the same problem with charger and usb extender but the problem doesn't stay when I take it out. I Won't be using it again that's for sure...thanks for the heads up

i was having screen freezes and stuff with my HD2 HTC desire rom using a 3rd party charger
my guess is , STAY AWAY

I have a JMB branded car charger ([email protected]) with a mini USB connector, but with a Force branded mini USB to micro USB converter. I have no issues whatsoever.

I use a Samsung Micro USB charger and I notice no problems whatsoever, it's like an older version of the charger that comes with the Galaxy S in Europe.
Straight from the plug as it were, it's great, no issues and charges extra fast

Car Charger and Wall Charger

As far as i can tell i have not had an shutdowns or lockups etc.. while using the LG charger that came with the G2x. I had been using the one that came with my Nexus One and it seems that almost every time i have used it, i would get a shut down or a reboot or black screen of death etc... usually at a full charge. ie i would wake up in the morning to a unresponsive phone.
Has anyone bought an extra wall charger or a Car charger that did not cause any issues? If so where? Did anyone buy the ones ("They call it a Universal charger" ) directly from TMobile? Since technically in the manual LG says to use their own charger..but i thought all manufacturers say that.
I am wondering if the one that came with the Nexus One has the built in circuitry for not letting it get to much voltage or whatever they are supposed to block. I have seen some online that say they have something built into the charger...which not having it may be the issue.
I thought the phone does ..switches to trickle charge when almost full. At least my Nexus did... but i get lock ups sometimes no where near full... with the G2x. And i get it every so often with my Car charger too.
Thanks

I've been using the ones from my HD2 no problem yet.. :knocks on wood:

Before you go out and buy a generic charger from Ebay, make sure you check out the miliamps on the chargers. The G2X AC charger is 1000 mA which is pretty high. My previous Samsung phone was 700mA which was less. If you buy anything that has a low mA rating it will take longer to charge. I bought a cheap generic charger from Ebay before and it was rated at 300mA!!! That's barely enough to keep the battery level the same while you use your phone or have it on. Don't use your USB plug from your computer because the mA is very low and you will run down your battery having your phone on. A good 2nd home charger is the Blackberry AC charger. They are under $5 from Amazon and they are 700mA.

For the car buy this Motorolla charger. 950mA! and about $6

Thanks for the input everyone. I will look into grenademastas suggestions.
Just an FYI... still
...as far as I know, i have not had a "self reboot" (well no lockups for sure... self reboot you have to look for i guess...) since i began using the charger that came with the G2x as my primary charger, for overnight charging.
I also started rebooting my phone once a day when i take it off the LG charger.
And also since i did this, I have not woke up to a "unresponsive" phone where i had to do a battery pull. I was using my Nexus Ones charger as the primary charger.
And i had switched from Launcher Pro to Zeam. So i will try going back to Launcher pro for a few days and see what happens. As i thought original it was Launcher pro causing reboots and lockups. Zeam is pretty fas so if no lock ups , i am not sure what i will stick with.

Thanks for the link, I ordered one for each car. Ive seen a few Micro USB chargers locally for $10-$15 but they never list the ma on the package.
My current charger can only keep up with the N1 when not running GPS. it barely keeps the G2X steady

Trust story. I found a micro usb charger in my closet and started using it the same day I got my phone because the cored was longer. It was taking FOREVER to charge and when it was at 100% if i started using it while plugged in it would still drain to like 97%. I was like wtf everyone said this phone charges faster than others. Then I checked the specs of the charger and realized it was the charger for one of my old bluetooth headsets and the output was only 150mah .

[Q] Original Wall Charger

So I was wondering if I could find the original G2 wall charger, the one that came in the box. I bought my phone from craigslist and that guy didnt have the charger for some reason. I've been using some motorola one and very happy with it cause it didnt have rapid charging and battery life was great too (not sure if the charger plays a role). But couple weeks ago the wire got loose and wouldnt connect properly, so I bought this: http://cgi.ebay.com/ws/eBayISAPI.dl...331986&ssPageName=STRK:MEWNX:IT#ht_1184wt_950
Ever since I've been using that my phone goes to 100% from 10% in two hours, and battery life has been bad too since using that. I have used the phone the same was as before, I even calibrated it again, tried it with setcpu and no setcpu, used edge only also, tried different roms, used just wifi only etc, and battery life still not same as before. I mean it has to be the charger right? Otherwise it wouldnt have made a difference in using a different one. So I'm trying to find opinions from you guys to see if I can find the original one ( I have no idea what it looks like) or a similar one from ebay/amazon. Thanks for reading!

What is the rated Output on the charger that you have? The stock one is supposed to put out 1 Amp (1000 ma). It isn't uncommon for it to go from 10 to 'full' in 2 hours, but just because the phone shows it full, doesn't mean its there. Are you charging overnight or just for that 2 hour period?

Yes I am charging overnight. Output says 5V, 1A, so I'm guessing thats 1000ma/1Amp?

The G2's cord is rounder at the USB end and the Plug- in end, but I would think it would not make a giant difference since I use a Motorola one since I don't know where my original one went.

OEM HTC charger
I'm not sure if your still looking, but i bought a Brand New OEM HTC charger from eBay. It was the same thing that came with G2. I'm pretty sure by the time you see this it will be sold but they list them everyday so just look at the sellers other items.
Since I'm a new user i cant post links, but the item number is 160619103766

That is the maximum current supported by the charger, but the device may request a lower current. Use something like Battery Monitor Widget or Current Widget to see how much current is actually being drawn over the USB port. The most accurate reading will be taken when the screen is off, the CPU is idle and underclocked, all radios are off, etc.
I had a cheap no-name AC adapter for my DZ, but it caused the touchscreen to go bonkers. I ended up buying one of these adapters:
http://canadacomputers.com/product_info.php?item_id=039726
Inexpensive, and having two USB ports is very convenient. One goes to my Mugen DZ charging cradle (phone + spare battery), the other to my BT headset. Any standard USB cable will work. It does not cause problems with the touchscreen, so I can continue to use the phone even while it is charging.
The best I've seen on a DZ is about 650 mA net charge, which means an empty 1800 mAh battery should be fully charged in about 3 hours.

I've seen logs of my dz charging at 680-780mA, so long as you have a 1A output charger it should charge the same. The output is the max rated output, not what its feeding to the phone to charge.
On that note most moto chargers I've seen are 700mA max out and same with a lot of samsung chargers I've owned. I use my original that came with my g2 as well as an old htc diamond wall charger with a sony usb cable lol, I get the same charge from both.

Charger Outputs

I know some people use chargers other than the stock HTC charger...
does using a different charger with lower or higher milliamp ratings make a difference or hurt the battery in any way?

Dont know anything about damage, wouldnt think so.
In my experience, my HTC desire has two modes of charging USB (500mA) or AC (1A).
If the two middle pins of the usb cable are shorted it assumes its connected to an ac charger so it pulls 1A. This is due to the max rating of a pc usb connection being 500mA, so everytime it thinks its connected to a pc it wont draw too much and damage your pc motherboard etc.
Now coming back to your question, some chargers have their pins shorted, some not. Apart from longer charging times, the only real issue is for car chargers, where some poeple have found that if you use one that sets the phone to USB mode, and you are running lots of thing like nav software etc, the battery will still drain even with the charger connected. ie its using more juice than its taking.
Personally I have charged my desire with many USB devices, like ipod chargers, etc etc with no ill effect. I found out thtat my ipod WONT charge from the HTC charger, whereas my phone would happily charge from the apple charger. Prob due to some usual Apple rubbish about who gets the accessory money, so for travelling I just take the Apple charger now.

Both my kid's iPod 3G charge from their Htc chargers just fine so I'm not sure why yours wont. I bought a dock last week for the phone and when I plugged it in I got the screen problem that a lot of others have had where it doesn't respond much. It was like this for a while after too. The charger was some cheap **** 800mA that came with it but I doubt it was just down to mA.

> Both my kid's iPod 3G charge from their Htc chargers just fine so I'm not sure why
> yours wont.
The Problem is with the generation and Software of the Ipod, older ones charge from
normal wall chargers i.e. HTC just fine, but newer ones are more picky. Notices this
myself with my Ipod Nanos...

you should be able to use anything up to 1.5A just fine with a usb port. Just watch for excessive over heating when the phone is on and charging. When its off and the usual over charge protection in many chargers these days they will stop once the charging has finished. I have a bunch of RC lipo batteries and have never had a problem with anything up to 2A+ for ANY battery i have charged no matter the battery makeup.. over this and you can get quick and significant problems...

Funnily enough mine is a very old 4G white one, the one with the round click wheel in the middle! But somehow it just refuses to charge...

that doesn't mean the device is not capable... you have 2 ends, the charger/usb port and the phone side.. the charger gives 1A, normal USB gives 0.5A, and only HTC knows what the phone side can take.. but at least 1A

HTC Sensation Xe takes FOREVER to recharge!!!

Hey guys basically my problem is that my htc sensation xe takes forever to recharge . I'm using a usb cable extension and a nokia usb cable that is connected to the black plug that htc gave with my phone my phone takes forever to charge!
And also while the phone is on charge and im using the internet the charge goes down!? And sometimes i receive a message saying the htc isn't receiving enough power while its on charge.
I have never used a phone where the battery goes down while using it while the phone is on charge!
Can someone tell me what i should do? Is there any other more powerful chargers i can get!?
Please im desperate if there isn't a solution im going to have to sell this (great) phone.
Thank you

It pays to have the original HTC charger and USB cable if I where you I look into getting both HTC charger and USB cable

If this configuration of the cables worked for you before, and had become faulty now it might indicate a battery problem.
If you're on stock battery it meant it had been used for over a year, probably close to 500 charging cycles. Unfortunately some batteries do not live that long
But just to be sure, try to charge the phone with a different charger (1A 5V) when the phone is turned off - really off, take the battery out, wait a few seconds and put it back inside, than charge.
Wait an hour and turn back on, see if the charge rate is more acceptable.
While the battery is in your hand, feel it and see it has not swollen, no shiny visible cracks and no tiny oily liquid marks. Those are positive signs for a dying battery.
Good luck

I'm guessing it's charging via 'USB' mode and not 'AC' mode. Check the battery menu while charging to confirm. If it is actually charging via 'AC' mode, the mAh must be very low.
I bought a 1000mA charger with the certified 'tick' for Australian standards for $10 off ebay. As I purchased my Sensation from Singapore, which came with an incompatible adapter obviously.
Takes about 1.5hrs to charge. Maybe 2hrs+ while playing 3D games (most intensive)
Not the same one but very similar. Don't worry about it saying it's for the Incredible, as its the same spec charger. This will definitely fix you problem. Did for me... Initially I had the same problem using the supplied HTC USB cord plus an old generic iPhone USB adapter. Which resulted in 'USB' charging mode and very low mAh.

Try with different cable because some cables have resistance (or ferit or both) inside and lower the current given to your phone that make it longer to charge (maybe that nokia cable has this ) See what I mean in attached file (make notice that some cables has this iside the microusb ot usb nozzle ) And try with no so long cable due to resistance of cable(not so big but making a difference ) It is not charger issue I think
