[Q] 3rd party charger - wierdness - HTC Sensation

I bought one of these because of the convenience of the 2 usb charging ports
http://www.amazon.co.uk/Masterplug-SRGDU42PW-Charging-Protected-Extension/dp/B007TQNUH8
As soon as I plugged it into my Sensation the touch screen became unresponsive often registering touches from menus no where near my fingers.
Once I had swapped between the HTC charger and this it was clearly a problem on the 3rd party product (which I believed to be a good quality one).
Before I bought this I made sure of the 5v - 1A rating which is what the HTC adapter provides so I'm really puzzled why I don't get this problem when plugged into a pc, a cheap car charger (1A) or my HTC supplied adaptor (1A) and an Anker charger with usb port (600ma), yet this supposed USB port is sending my HTC touch screen haywire.
Can anyone shed any light on this? Needless to say I won't dare use this for the HTC and I'm loath to plug my other intended device (an Asus tablet) into it. I'm a little worried about damaging it but if it's a USB port it should be a simple standard ... shouldn't it?

Same... I have 3rd party charger too for my old Mobile..
Output of that China charger is written same as on HTC charger
When I try to charge my sensation with this charger , entire screen gets unresponsive
My old chaina mobile charge fine with that charger

That's interesting, thanks for the input. I wonder if this is something to do with over-voltage or poor regulation in general. The Masterplug is supposed to be a good make which is why I opted for this rather than the ebay offerings from China.

I have some weird experience before too with 3rd party charger, my xe auto redial the last contact i called out, it call and hangup by itself continuously until i remove the charger, i put back the charger and it did the same again... then charger in bin

Sounds like a grounding issue or voltage regulation perhaps.
It's not worth getting a cheapo charger.
I got an original HTC one with cable for £8.

Understood, however, the product isn't what I'd call a cheapo like the chinese ebay offerings. Masterplug I believe do a range of high quality surge protectors and sockets for all applications so I thought it would be a reasonably safe bet. I already have the HTC charger but this was a convenient way to do away with all that bulk and have a couple of convenient charging sockets.
I'd love to know though what is actually causing this kind of reaction on the phone .. curiosity now more than anything.

Warning: HTC CC C200 (Genuine car charger)

Hi,
I bought one of this HTC CC C200, HTC genuine car charger for micro usb.
Problem is ... it does not tightly connect to the car power source (the cigarette lighter). It is very loose, you must push it downward to connect. Even then, it does not connect reliably.
I dont think this is an issue with my cars, I tested on my Peugeot 206 and Toyota Yaris. Both has the same problem like this.
Well, this is just fyi.
Wasted 22 euro
Yup. I know this one. Have seen chargers that don't fit the socket properly. The right charger should look more like this. http://i.expansys.com/i/b/b140838.jpg Take note of the collar just in front of the silver pin at the end. The collar holds the charger in place. I had an exact charger like this for my Diamond2 and it fitted perfectly. It's not the cars fault. All the sockets in the cars are the same - normalized.
Yes, that's the one. I have couple of them actually. But they are for mini-USB.
I was thinking to buy the converter from mini to micro. Then, I thought, Ok, new phone ... why not new charger? ... Then read suggestion to buy genuine HTC car charger. It turned out a mistake.
I think, this would be fine:

Yea, should work. But You need to be superduper sure about the Amps output of the charger. There are stories on the forums about chargers that are too weak to charge the phone during GPS + GPRS operation. I wonder if they would menage to charge a phone operating just the GPS (non GPRS related turn-by-turn navigation program). Anyway, in case You buy one of these, give us a call if it menages to charge the phone like it should.
Thanks, I read that thread, that's why I bought that HTC CC C200.
From the picture above, it said: Output 5VDC, 1A
Is this what we are looking for?
I know, it could be different in reality.
PS: Is there any tool to really measure this output?
i use this one :
http://www.belkin.com/IWCatProductPage.process?Product_Id=489767
About 12/13 €
I have the original charger and have no problems with it.
I have the HTC C200 unit and it fits perfectly in my cars lighter socket without any issues.

I have original HTC C200 charger and it fits without any problem in cars lighter - Ford C-max.
Do you need to really push it down?
Will it "click" to the lighter?
I tried to push it and I saw the "HTC" text turned on ... When I loose my hand, it turned off.
As I said, I was thinking this is an issue with my cars (Peugeot 206 station wagon, Toyota Yaris), but both have this loosen issue.
I purchased the HTC CC C200 also and have exactly the same problem. My car is a Peugeot 206. As you say, the charger needs to be pushed quite firmly in, and with mine, the side connectors need to be aligned also. Its okay when I've found the right position, but the slightest touch against the device can easily stop it from charging. I haven't decided yet whether to request a refund/exchange for something else.
Nope no need to manipulate it to keep charging. As soon as I plug it in the HTC light comes on and I can twist the unit and pull on the usb cable when its connected and it keeps charging.
Tried it in both a Mazda 6 and a Holden Commodore and fits snug in both cars.

Same issue with my Opel Corsa B.
In car charger
I bought this one:
http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=380220708739&ssPageName=STRK:MEWNX:IT
For £1.95 including delivery.
Works a treat in my Skyline. (clang)
Guys,
I see some of you suffer from a loose connections with the cig charger.
The two metal trips on the side of the charger are meant to keep the charger in place. And its a contact point ofcourse. Its a kind of a spring. You can easilly try to use a scewdriver to flex/pull it a little bit more outward. It probably needs a little push like that for it to stick in its place.
I did this once and it worked after 3 minutes of fiddling.
good luck

I have the OEM charger and have no problem in my MINI
i got two original htc chargers and had the same problem ( wouldn't stay in charger and would pop out very easy ) i bent the metal clips and was ok .but then the charger wouldn't work .there is a problem with the cable at the mini usb end ( charger was for a diamond ). my problem is that i think they are original but really might be FAKE chargers
any feedback on the output of this charger? i've recently purchased the belkin 1amp usb charger however this is not sufficient to power the phone during heavy use (gps, sat nav, music player etc). can anyone confirm that the official one can?
I have the original charger as well. Just take some care when pushin it in and it works fine.
Can people tell which charger gives enough power to charge the Desire during heavy use (3G data+gps) ? My old one (Genuine HTC Pharos) is supposed to give 1A but my Desire keeps discharging (slowly but surely).

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 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

Problems with Galaxy S and 3rd party ac adapters!

Yesterday night I was playing with the phone before sleeping. It was charging not with the provided ac adapter, but with the usb-miniusb cable + an aiino usb-ac adapter. Well, the weird thing is that using google maps, the touch/multitouch control was completely f****d up. I mean, it was impossible to pinch-to-zoom, using the zoom buttons worked, but when I used only one finger to move around the map, instead of moving it was zooming randomly in&out without a reason. So I unplugged the cable and it was working perfectly...
It seems your 3rd party ac adaptor is not appropriately grounded so there is a small current on the touchscreen. Capacitive touchscreens recognize minimal changes in currents on the surface. That's why fingers, oranges, organic material work with it, but no stylus or other pens.
Hmm that's an interesting point, I didn't think about that. Do you think I should stop using that charger? Could it damage my device in some way?
I got it with my iPhone 3GS on a car charger too. But it didn't hurt the device at all.
I cannot guarantee this though...
I always used it with my iphone 3g too, and also used my iphone while it was charging...but I never had such an experience on iphone's multitouch...that's really strange!
I had the same issue with a generic ac micro usb charger I bought on ebay.
Since the phone was just newly released, there seemed to be a premium on the chargers described as being for the galaxy s so I went and bought a much cheaper micro usb charger compatible with motorola devices. I figured the contacts would all be the same and all micro usb chargers the same.
Wrong.
As soon as I plugged in that charger, the touch screen was borked. The display was fine but the touch response was shot. If I tap the application drawer in the home screen, it would register a click on some other random spot on the display. The phone was utterly useless while plugged into this charger.
To troubleshoot, I tried mixing it up between the original samsung charger and the generic, resetting etc, and it always came down to the charger. Crap with generic, prefect with original.
TL;DR - not all chargers compatible with samsung galaxy s, borked touch response from generic charger.
Perhaps it would be useful to change the title off this post and move to the accessories forum? Useful for people to add their feedback on generic chargers they've used.

Btw, the charger did charge the phone but I guessed having extra current run through the screen would damage the capacitive sensors.
Compared to the original samsung which has 4 contacts, the micro usb plug on the generic had an extra contact. I tried to open up the plug to see if I could do something about the extra contact but it broke and I the it out.
Shame I didn't think to make a video to share.

just a warning to others, you may want to spend the extra money on a charger that specifically says it's compatible.

This is definitely something to do with Capacitive touchscreens.
Similar thing happeend to my ipod touch 3g when I used a 3rd party wall charger on it
How bad is it to our phones ?....
I would like to know what is really happening.
Is the usb charger "ground" at an important voltage relative to earth ground ?
Is it at a variable voltage, which would even more confuse our phone ?
Could we safely ground it, and how ? (connecting the usb ground to earth, maybe via a grounded 220V plug ?) .
I think anyway I will at least mesure the voltage (and maybe leaking current relative to real ground) level of this usb "ground"...
Any electronician to explain how it is normally done in quality chargers ?

I'm not sure what ground here is! My e-bay travel charger 4.7v 500mA with a Samsung logo has no ground connection on the charger - normal in Europe. Problem probably is that it is possibly not a Samsung unit at all - well it only cost 1euro - It does charge and the screen does freeze until I disconnect it. Only got it today - but nothing is getting hot and no other problems so far. The voltage rating is of course less than the standard 5v.
Bought a Belkin Dual USB car charger (1.0A + 0.5A) online. Will report back.

My best shots would be no ground (mass) issues, but:
1. stability of the charger output voltage
2. stability of the charger output current
3. value of the charger output voltage
4. capacity of the filter capacitors in the charger (too little - 50/60 Hz hum is distributed to the output)
5. Is the charger impulse or stabilized?
Capacitive screens must be very sensitive to changes of impedance and if there is no stable voltage or current or if the output is interfered with electrical network hum, the touchscreen may go crazy in my opinion...
edit: format tags corrected
Working fine without any capacitive screen issues.
The good thing is it works as charger mode instead of USB. So I assume the 1.0A socket would actually charge faster than USB mode.

It will be high-frequency noise on the DC output voltage of the charger. Chargers use a high-frequency DC-DC converter method and the cheaper ones don't do a very good job of filtering the high frequency out of the DC at the other end. This noise enters your phone and plays havoc with the sensitive circuits in the capacitive touchscreen.
It is nothing to do with grounding of the input side of the power supply; when you ground the output side (the USB plug) with your hand, your body capacitance filters out some/all of the noise.
You could probably filter this out by adding capacitors or whatever but really, the solution is don't buy $1 chargers for your $x00 phone.

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.

[Q] where to buy HTC Sensation genuine AC charger?

I Don't want to fall into fakes or Replicas that take twice the time to charge... So please a genuine charger link...
Expanys us, Tmobile, Amazon. But the charger is just a generic HTC wall plug and a USB cord . I bought the wall piece from Ebay and the USB piece too.
Sent from my HTC Sensation Z710e using XDA App
you can use pretty much any wallplugs that support USB out. I've noticed that most of these chargers output at 5V and 1A so they shouldn't be a problem
I've bought a couple of cheap generic ones off Dealextreme for about $4 each so I could leave them at my girlfriend's and in my bag and they work well.
I got a genuine Samsung and it charges in just over 2 hrs from 0
becareful dazdeeuk, fast charge is usually bad for the health of the battery. Generally, I would recommend sticking with factory specs (usually 5v and 1A)
Most manufacturers have signed up to the universal charger agreement now so you can't go wrong with any decent brand micro-USB charger. I use a BlackBerry charger in my bedroom and car.
I tried one from Sony Ericsson... its 850mA and takes almost 4 hrs to charge my mobile.. and longer if I keep it busy...
Want a link to real genuine deal if anyone knows a link..
