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

Use another charger?

My phone always discharges at 2-3 pm , and i have an extra charger from my motorola milestone, i was thinking of leaving the htc charger here at home and carry the motorola charger with me, but the inspire manual clearly says i should charge it ONLY using the htc charger, what do you guys think? its just nonsense talk? i must say that my milestone screen sometimes acted CRAZY, like it was possesed and random things clicked by themselves , i was told it was because i was using a blackberry charger that had different voltage

If you have the ability to do so, just use USB charging from the computer. No drivers needed and no worrying about potential power issues unless it happens to be a bad port.

You can use the other charger. Lithium-Ion batteries have fail-safe circuitry in them. If the charger is producing current outside of the pre-programed range for that battery, it simply will not charge.

Your phone is discharging at 2 am? Sounds like a wet dream to me...
Tribal is right though.

I've used universal usb car chargers (many I received for free or bought very cheap) with anything that uses usb port to charge the battery. From IPod to most of the Cingular, Sprint and AT&T phones and never had a problem. I always figured that the usb port voltage had to be regulated from the device end considering that all the different devices that plugs into them.

i charge overnight with teh charger from my htc tilt2, but i always carry the inspire charger with me on the road because it charges FASTER than the other chargers i've used it with (PC included). but no, chances are that you wont damage your phone or anything by using another device's charger.

Using GPS discharges battery... even if connected to car charger?! - SOLVED = post 8

Hi,
Today I was using GPS app - HTC Locations. In about 45 minutes battery went down from 100% to 50% (I noticed that using satellite GPS makes the phone very hot) and I decided to connect a charger that I have bought recently - HTC CC-C200 car charger.
The problem was... the battery was still being discharged!
I turned off the nav app and left only basic system apps and the phone was charging only about 5 percent in 30 minutes. Keeping in mind how fast the phone was discharging using navigation, it is simple that the car charger won't do.
Anybody else has this problem? How can I actually use a navigation??

is it the official car charger from t-mobile.

It is original HTC's car charger - CC-C200
One question - can an USB extension cord (plug in to this original HTC's charger and then original HTC USB cable to this cord) decrease the speed of charging?

Car chargers will always charge slower. 12v vs. 110v.

Are u sure that the 110V network adapter, charge the phone with 110 volts ?
The 110V charger:
HTC New Slim Design AC Adapter TC E250 (with EU Plug Unit + micro USB Cable, 5V/1A
and the car charger:
HTC Generic Car Charger with USB/micUSB Cable CC C200 (1A/5V)
have SAME charge power: 1A at 5Vm that is 5W.
The PC USB ports are rated at 500mA, but if u check the port with digital multimeter (cut the cable and put Ampere-meter) u can see that u can drain ~700-800mA , Asus and SuperMicro Motherboard tested from me
@EniHS if u make the lenght of the cable bigger the electrical resistance grow too . I think that 1 meter more wont be such a problem, but if u really wanna check how this will change the power of charge u need to measure it with Ampere-meter

This is an easy one... I try to never get the charger from the store because it (usually) won't put out enough juice to keep up.
I found that if use the same current for charging my ipad, it works much better and can keep up. With that in mind, you can purchase any charger with a 2 Amp output (10 watts) that has a generic USB connector. Try the search "10 watt usb car charger" on Google or Amazon.
Get the free app "juice plotter," which will plot your battery usage and charge. If you're plugged in and the plot is still going down, then the drain is still greater than the charge, and you'll need a better charger. Good luck!

That would be a solution. I'll buy 2A 5V charger. I assume that I should only replace the plug and the USB cable can be left from original HTC car charger?
Isn't it dangerous for the phone to charge by 2A instead of 1A (original charger)? Or the only difference is the charging speed?

Solved!
I did some tests today and discovered that if I charge the phone normally (no program running, GPS off) with HTC car charger WITH extension USB cable... phone was charging 1% in 25 minutes!!! That would be over 40 hours to charge the device from zero to full! I thought I had charger broken, but... I tried with NO EXTENSION CABLE, just the HTC plug and HTC cable, then the phone was charging normally 1% in 2 minutes!
So... the problem are extension cables, but still don't know why...

I noticed this even with wall chargers. Yesterday when I bought my phone, I plugged it in to my old charger & noticed it was charging slow. Once I switched to the charger that came with my Sensation, it charges normally now. I haven't looked at the chargers to compare if something is different but it is very strange

Isn't strange at all, it's essentially that they are not being supplied a great enough charge and so power from the battery is utilised in addition. ideally you want above 700mAh for standard charging/use.

[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.

Charging slow???

Out of the blue I noticed my S3 was charging very slowly, it even was losing a charge while it was plugged in while I was using it. I figure it had something to do with my custom ROM so I reflash, still same outcome. The battery was still holding a good charge, so I figured it was something else. I then went out and bought a new charger, which came with a micro usb cord to see if that helped. Plugged in the new charger while using my old micro usb cord, still same outcome. Then used the new micro usb cord and old charger, charging went back to normal, problem solved! I would of never thought that the cord would malfunction from day to day use after such a short lifespan. Moral of the story, check your cords if you experience the same problem, it could save you some time and money!

I bought some cheap ones off Amazon. They won't charge the s3 but will my touchpad. But my s3 charger won't charge my touchpad. Stuff is weird at times.
Glad it was an easy fix.

Must have been charging in USB mode.

I believe it, using my old galaxy nexus cord for my s3 charges extremely slow (like 200 mAh) for some reason. I switched to a different cord and now it's all good, I have no clue why but that's how it is.

That's weird mine started doing the same thing just in the past few days. I have to unplug and plug it back in multiple times before it goes into AC mode

I really think that those cheap cables don't charge nearly as fast. Especially the Stock Sammy ones. I use the thicker LG cables and they seem to charge so much fast and transfer files faster..

I just went through the same thing. The phone was charging for twelve hours and only gained 50 percent. Took forever to figure out it was the cord.

USB Cable
I think charging AC is not fast charge.
You should to charge USB cable.
Thanks.

That's what my phone was doing, I'd unplug then plug it back in and would go from USB to AC, but it still charged slow. That cable, no matter what it said, would still charge slow as balls.

I had heard of "Buy Cheap, Buy Twice", but now we've got "Buy Cheap, Charge Twice"

A lot of times it's the DC power brick that makes the difference. Not all of them have the same power output. Rarely, if ever, is it the actual cord itself. USB cables use pretty thin gauge wire already and the only way you're going to get a difference from one cable to another would be if it was REALLY cheap and using an ultra-thin wire or if it was a REALLY long cable (increases in cable length equate to increased resistance to electrical transmission...)
All USB cables are 5 volts. However, there can be significant differences in the milliamp output for each DC adapter. Aside from being a computer geek and gamer who builds custom PC's, I happen to be a hotel General Manager. I just checked our catch-all box of phone chargers and found that while every charger has an output of 5v, the amperage put out varied from 350 mA to 1000 mA from one charger to the next.
This variance in output is why some chargers take so long as compared to others. I don't know what the actual Samsung charger output is, since my charger is at home, but my guess is it's between 800 and 1000 mA.

I use the stock BB charger to charge both my 9900 and GS3, the BB charges pretty normal but lately I've been having a problem with the charging time on my S3, I have to charge it everyday now, my usage isn't that heavy, it lasts me a day and a half normally. Going to start using the stock charger to see if there is a difference.

I'm using the Samsung stock charger after not having used it for a month and noticing that my battery levels have deteriorated after using my BB stock charger. The battery seems to be discharging while on the charger! I'm in for a world of pain, going to monitor it for a while. I could be stressing over nothing.
