HI friends after my last charger got lost I am looking for another charger but as I am not able to find a right one I am forced to charge it with my PC USB. May I know which is the right charger I mean the voltage because I have a mp3 player charger with USB plug. Can I use that it differs in the voltage up to a very less extent. Is there any harm of using duplicate or different companies charger. I have heard that motorola charger works with HTC devices as well. So plz guide me friends with Your valuable comments..Cheers
The output on my charger is 5v--- 1000mA. I have a similar charger for my Motorola S9 stereo bluetooth headphones and use this to charge my phone but this is 5v---850mA and I have noticed that although it charges the phone sometimes the charge icon does not light up.
I sometimes use the phone charge to charge my bluetooth GPS but although it charges fine the GPS won't work at the same time as I am charging, which it will do with a PC USB lead or even the Motorola charger.
I would try and get a charger that puts out 1000mA. (1A)

Yes, very much agree with that. Non official chargers are OK as a stop gap until you get the correct 5v, 1000mA one. Some quirky things can happen using lower power ones. (the mini usb connector is wired slightly differently and this can have some odd - but not usually damaging effects).

Hey guys. Got an aftermarket charger after my original gave up on day one and i didnt want to have to send everything back. When i plug the phone in the scren becomes un responise, but the hardware buttons stil work. Can anyone explain this? obviously i ned to try a diferant charger, specificaly for the galaxy but how can the charger stop the screen working? Many thanks.

Yes the same thing happened to me,,i took the charger back..and got a proper one
just for reference, the Black Berry 9600 chargers are compatible with SGS 9000
i bough one for car use
So are the moto chargers.
My car charger is an old razor v3 mini-usb with a mini-usb adapter.
My wall charger is an old Razor v9m charger.
Never tested a BB charger as i have always charged mine with the moto ones that were already plugged in
yup i also purchased a mini usb to micro usb adapter to use my old Moto chargers with my SGS
The same happened with me while using the stock charger in a train. The capacitive touch buttons and the screen stopped working, but the hardware buttons were working. So I plugged in my laptop and used a USB cable for charging it.
Never heard of this before....
I've not come across a charger that does not work.
The chatger works but the phone doesnt while its plugged in! my back button and menu button still work along with hardware buttons...... Weird... Allready ordered an official replacement

That will be the cable that has issues.
Pity you couldn't have tried another cable.
I am using a nokia car charger, also works fine. Blackberry didn't work for me
Yeah i know the cable causes the issue but does anyone know how? obviously other after market chargers are ok... Phone charges fine too, just cant use it when charging...

i'm using After market chargers too, but i have no problem
my car charger is using a BlackBerry 9500 charger (2A)
an in my PC i use a Motorola sync/charge USB mini + micro USB adapter to make it compatible with SGS 9000
they all work fine
i have not even unpacked my SGS usb cable that came in the box
Is any of this chargers really recognized as charger (charging with more than 500mA)?
You can easily verify this with the app "OSmonitor".
IF you see this: "USB Power: Online and at AC Power: Online" everything is working as it should. But if you see "AC power: Offline" your phone thinks the charger is a pc and it will only charge with 500mA.

The only problem with software informers here though is for those that have the problem and the screen locks up whilst being charged the software is of little use.
This question was not for people having a faulty charger but for the ones claiming that they have a functioning charger!
If the charger is not really recognized as charger it is useless for navigation. As the Galaxy S need more than the 500mA while navigating (with GPS).
yeah, minimum you need a 1A (1000mAh) charger
that's why i prefer the 2A chargers, it gives just enough juice to actually charge the battery, and use GPS+3G+WiFi+Bluetooth
else the car charger will not even be enough to power all those, and it will still consume the battery power.
that's from experience from my HTC phones

I bought a Sharper Image Retractable USB kit that has adapters for most of the USB sockets out there. But the Micro USB that came with the kit fails to work with the SGS, the retractable USB cable is set up like an extension cable which works fine as an extension cable but putting on the adapters dont work.
When I charge the Streak, I cannot use the Streak well.
When I try to do something, the screen is jumping to other screens by itself.
Anyone this problem?
You have to use the Dell charger and cable, not anyone else's...
Tom.
maybe you have some wire near the device. magnetic interference.
what i have succesfully used to charge my dell streak :
-car charger from motorola 1 Amp with converterplug
-normal car charger (most of them are 500mA which is fine)
-my htc charger (1 Amp)
-other usb wall charger (500mA)
-pc
-hama usb reader self powered.
-usb port of car-stereo
-usb port of a philips stereo
-usb port of panasonic/sony/philips tv
in general any usb port will do fine to charge. the only time one needs a 1 Amp charger is when the battery died out and it wont charge on usb anymore and wont turn on.
I see that issue when I'm plugged into the computer. I can tell how bad it is because I can't even use swype - my blue 'trail' goes crazy all over the place and its tough to scroll/switch screens. But... don't have that issue when plugged into the wall charger. Maybe a bug? I know there are plenty of them with stock 1.6...

Yes, I am using the original Dell cable and charger.
same here, and this problem I found also on my Motorola Droid X....I dont know about samsung galaxy S since I have sold it
but for sure, Motorola Droid X and Dell Streak have that problem while charging
do you have it attached to a self-powered hub ? if so that could be it. try attach it to pc usb directly.
The streak goes crazy if you are using it from a non harmonised power supply - I have tested this personally and find that the capacitance of the srceen is affected if the power supply does not have a perfect flat signal.
This commonly occurs with switched mode power supplies, which can impart a 50Hz voltage drop-off "click" into the signal - laptops, small footprint desktop PC's, as well as the 12V-230V power invertors used in cars to get a mains socket. This caused by the way it rectifies the AC signal into a DC signal and there is nothing you can do about it.
An oscilloscope shows it well, but I doubt everyone has one of those in the cupboard under the stairs...
Simple answer - change your power supply, or don't charge the streak this way!
I'm on a road trip now and every time I connect the phone to a charger it switches it self off.
I have tried different cables and chargers. This also happens if I connect it to my Mac.
Is anyone else seeing this?
Thank you
Funny you should post this, today is the first day at work with my DVP and I tried to use a USB cable connected to my pc that charges my HD2 and SE MW600 headset, connected it to the Dell and it turned off just like you say. Probably not enough voltage/amps, I borrowed a BlackBerry charger and that works fine.

I noted this in my "Nit-picky" stuff post. Needs a 1Amp charger.
Same here.
The only charger that worked is the one that came with the DVP.
I tried the 1A iP4 charger, 750 mA of the Kindle, a third party dual 1A (each) charger, 1A car charger, 2.5A iPad charger and finally my computer.
None of these works, but if it has like 50% charge then it charges with any of the above...

It wouldn't even charge from your computer below 50%??

No...thats not true....But I have seen several different combinations work.
I have the Nexus 1, one of the Jawbone headsets, the HD2, HD7, DVP, and have access to the Focus and LG devices. All of these use the same type of cable.
The HDx cables, the Focus cable, and the Jawbones cables all work with sync and Charging. The LG cable does not...only works for the LG. Some of the older BB cables will only provide a sync or a charge...but not both.
The different USB charging adapters have different results also.
The DELL and HD7 adapter will work. They will work plugged into a wall or a power strip. The jawbone and HD2 usb adapter will not work plugged into a power strip at home, but, both of them will work plugged directly into a wall.
All the cables I have will work when plugged into a laptop, EXCEPT the LG. Apparently the LG cable I have access to only works with an LG.
Now to be honest, the HD7 shows no such reluctance to charge with any combination. The DVP does. My DVP does NOT require DELL only parts, but it is picky about what it will play with.
-My overnight charger is connected directly to the wall. It is a jawbone wired charger, no adapters or usb. All phones connect and charge ok with this.
-My Work office charger is a HD2 usb adapter with the HD2 charger cable.( which is strange because this one will not work at home plugged into a power strip.)
-My HOme office currently uses the Dell adapter plugged into a power strip with a generic sync cable. I say generic because I don't recall where it comes from...all I know its not the DVP or the HD7, because both of those cables are still wrapped up in the box they came with.
-My car charger is an ATT dual USB charger. It has last years model adapter, plus a USB connection. All my phones and head sets charge off of this combination quite nicely. I also have a Tmobile care charger but have not tested it yet.
There is definitely something different about the DVP and charging. I'm hoping Nicolas Cage will play the lead when this conspiracy is made into a movie.
the DVP will only charge with a 1A+ charger. the ones that come with BT headsets don't feed it enough to charge. USB cable plugged into a laptop USB port is hit or miss. The USB port in my car is 1.5A, charges the DVP really quick. I haven't found the make of the cable an issue, the DVP charges with any I've come across so far, HTC, BB, the cheap extendable cable from an airport, etc. it is picky about amps.
The cable is not the problem. I didn't mean that when I plug different cables it does not charge.
I have a charger hub which I connected many phones to it, HD2, palm pre, nexus one and few more and all of them charge from it. When I connect the DVP it shows its charging but in the morning the phone is dead, no charge at all.
BTW, it does charge from my laptop and desktop.
I charge my phone overnight on my PC and never had this issue

It will charge from the mac from 0... then when its about half charged it charges from any plug and cable combination

I can't get mine to charge now at ALL..
Apparently it drained and shut off in my pocket. Went to charge like I normally do.. and NOTHING..
I noticed a weird behavior yesterday when charging it would jump from charging to not charging to charging. While sitting on my table. NO MOVEMENT to the cord or anything.
Tried Dell charger, tried aftermarket one (that I have been using for 2 months), and PC USB no response from the phone at all. Even tried to swap to a battery I know was low but not dead. Still no response from the phone.
The connection looks good.. but I am thinking maybe I am having a problem with the connector in the phone ?
Took my sons battery out (He also has a DVP) and booted my phone. Plugged it in and it started to charge. Then hot swapped batteries while it was plugged in.. let the battery charge up to 25% and now it charges fine again..
FUNNY it won't boot or charge while plugged in with a dead battery.. but will stay on if booted up and you remove the battery in it..
I just received my stash of charging gear for my Optimus 7 today, bought from DX. Having read everywhere that USB chargers are 5V +/- 10%, and seeing that the original LG charger outputs 4.8V, I thought my purchase was ok and that this charger would work.
Turns out it doesn't. When I connect the phone to the charger via USB, I lose control of the touchscreen and the system gains a mind of its own. I literally just hold my phone in my hand and stare while it randomly enters hubs and either opens an email message or dials someone. The physical buttons still respond correctly, and it's not until I disconnect the charger from the wall socket or the phone from the USB cable that I can regain control of the phone. My guess is it's a hardware fault and not software.
Granted this unofficial charger cost me around $1, but I got some similar 5V car chargers to go with it, and I've never had problems with other USB chargers.
Unofficial charger specs:
Input: 100-240V 0.15A (0.15A) 50-60hz
Output: 5V 1A
Does someone else have this issue? Is the Optimus 7 an uncommon device for requiring 4.8V input instead of 5V?
Your problem is NOT the charger, as that has nothing to do with the functions of the phone.
Your problem is that your LG Optimus 7 E900 is a DEMO unit, with a DEMO ROM. And until you flash a stock ROM onto your phone, you will experience the demo played out while connected to a power source.
You sure? Because I tried it with the 5V 1A car adapters and no problem, and the original 4.8V 1A charger gives me no problems either.
How do I check my ROM version? Firmware is 1.0.7.10, OS is 7.0.7008.0 after the February update.
Can you get us video on this?
Please excuse the ****ty video quality
That is most fascinating. I recommend you stop using that charger on your phone
So, obviously, you do NOT have the demo ROM as I suspected initially.
Since you say it works with another 5V 1A charger, then I think this specific charger may be sending unexpected, random data signals down the USB cable, resulting in the unresponsive and bizarre behaviour. Since the original charger works well, and charges pretty fast, just stick with that for now.
At least you got the update, here in Canada, we are still waiting for our first update.
And your English is so good, and without any accents...Are you sure you aren't from our here (North America)?
This is true magic Really I have no eplanation on this problem. It is only 0,2V
Yeah, and there I was thinking that the whole point of USB charging is that it's universal and totally compatible, no matter what adapter you buy and what cable you use, provided it connects well.
It seems this is not the case, and I'm weary of trying another third party USB charger, as I still cannot tell if this phenomenon is unique to the Optimus 7 or not. Sadly, the only other MicroUSB phones I have lying around don't actually support charging via this port, just data transfer.
i also admit that im "dazzled" by ur -smart-phone...
probably that adapter is"magical" somehow... did u try it on another phone??
+i also use different chargers but never had any abnormalities so far..
Though i use the original chargers that came with my blackberry 9700 and htc-desire, and just checked the blackberry output is 5v!! i cant read the htc...
So, probably that adapter of yours is a "mutant from another place"...
confirm, htc is also 5v...
ps2- i'm also on 7008, and havent got any issues with charging on both 7004 and 7008
The problem is in the charger, it's too chinese . I had this issue with other touchscreen phones, like SE X8, X10... Just change the charger, obviously it has some hum/noise...
lol...
too chinese? lol
im having the same issue when i use the lg power adapter.. it doesnt always happen but when it happen the touch screen just when berserk.
i always thought that it happens on all units. uh oh
To be honest, I thought you were crazy till I bought a Chinese adapter as well. Don't know the voltage, but I'll check it tomorrow. I think it might have to do with the way the unit is shielded, or not. The only time I wiggs out is when I leave it on the desk, but as soon as I pick it up and pull it a few inches away form the desk or any other object it works fine. But as soon as I put it back down, the screen does the same thing.
I have a usb plug that I plug into the computer that didn't do that at the same desk, I'm going to bring in my other charger and see if it rule out the outlet / interference or just the cheap a$$ adapter....
The only part that worries me, and the only reason I might stop using it, is it takes a bit from the time I unplug it to the time the phone realizes it's unplugged and the charging icon stops. Which doesn't happen with any other charger.
I had this problem too.. until I realized it affected my other touch screen devices too (Galaxy S, Galaxy Tab)... Turns out the 5V charger was the problem. Replaced it with a 5V charger of Philips/Belkin/Samsung/LG and all worked..
The unbranded 5V chargers don't work well with capacitive screens as they seem to be letting off some extra current.
