hello
If I use not genuine charger or a icro usb cable ( want to extend my cable) will it charge the same ? meaning as fast as the original ( lets say the output are the same)
since I extended the original cable with 2M and used original charger and the charger is less hot when its with the normal length meaning it charge the battery slower ( + did a test) is it normal or I am imagining ?
I do not think you are. You're probably used a lower quality cable for the original extension.. Cable cross-section must have the same quality wire to prevent any losses.
I now but maby there is a chip like apple do ??? and like the mhl hdmi cable for galaxy s3 ...the s2 mhl wont work on s3 beacuse of a pin or a chip I dont remember

Hello,
I was looking at getting a USB adapter for mains so i could charge my S2 using the USB cable provided. The original charger outputs 5V=0.7A.
I've seen a car USB adapter that outputs 5V=0.8A. Does the 0.1A increase affect the charge? Or will it be ok to use on my S2?
Furthermore, I've seen 2 mains USB adapters which output 5V=0.5A and the other is 5V=1A. Which of these would be better to get?
i'm curious about this as well. but if you look at other threads,
quite a number of people says that higher current rate doesn charge the phone faster or damage it. the S2 will capped the charging current to 650mA.
so no worries mate.
I occasionlly charge my sgs2 with my ipad-charger, which got 5V=2A.
Haven't got any problems with that, but it doesn't feel faster.. probably not recommdable. :-/

SGS2 capped to 650mA via Mains charger and 400mA via USB.
Can only be changed by using a custom kernel.
Using a charger with a higher mA wont hurt the phone, it just wont take advantage of it.
I think this is related Electrical knowledge.
for example, 5V x 1A = 5W (power). That means the transfer max. output power is 5W. If your transfer power is larger than your phone demand, that's OK. Will not damage the phone.
But i dont' know the phone charging demand

adapter?
is it the original wall charger and the usb data cable.?
i too had a problem with an ordinary usb data cable. it charges so sloow. like 1%/20 minutes.
better use the original accesories if its the original one and defective better return it for replacement.
It's probably a cabel problem. Charging occurs only when pins AC and Ground (1 and 5 AFAIK) are both connected, and often some of the pins stop working. If it's not a kernel of power supply problem (Which it probably isn't), it will be solved by simply changing the cable. Or if the cable works in usb charging, buy a new adapter (Make sure it's 5V before buying).
I had the original charger, then broke it...
I bought an USB to replace that(the connector was messed up)... but that charged slow, and discharge when using...(still on the original charger, but another cable)
For 2 months, I borrowed galaxy chargers, and any other friends with cables like mine, I asked them for the charger...
Then, I decided this must stop! I told my mom to find me a galaxy s charger (she was noob, doesn't know I can charge from non-lg cables)...
She found me one, and all fine...
But, before trying to buy one of those, go to a friend with a charger that fits Optimus one, and try it, if it charges faster, then buy a new charger

my mothers camera does not charge with a usb cable while when I put the cable in the camera the charge button is on.
I did not know there are still differences in USB cables ...

Our stock charger uses a wall "adapter" and an usb cable... it charges from usb, but the chargers that have no adapter (you can't remove the usb from it), charge lot better, I recommend using one of those... any samsung charger that "fits" in our phone is better than stock charger
In mine it charges rarely ! i had lg normal charger but it stops charging if i lift the cell nd use it! den took my moms samsung pop charger ..it worked fine for few weeks den again same problem arised :-S

I lost mine. I bought 2 for one deal from ebay (noname cables) and they wont charge 30% during al night. So i told them it's faulty and they sent 2 another one. still no charge so i bought an htc one wich seems a bit better, but still not like the original. My friends lg optimus 3d cable was charged it full from ~70% in about 30 mins. His another htc cable was worked fine.
Can anyone else tell me if they have any issues charging the sony xperia using an adapter other than the one supplied?
I have one that I use for everything, iphone, kindle, garmin watch, sansa mp3 player. Yet when I hook up the sony usb charger cable to it the battery light blinks and viewing in the battery section of settings shows it alternating between 'charging' and 'discharging' at the same frequency as the flashing light. This frequency is roughly 1 second. I managed to stabalise the charging on this OEM adapter once. It always charges perfectly on the supplied adapter.
Also I have a portable 5V charger that again I use for all my gadgets as listed above. They all work fine. Not the sony tablet. 'Charging is not supported with this accessory' I'm told this time.
This tablet is looking worse and worse to me. The fact that this tablet was supposed to be bog standard 5V and came with the usb setup (making it simple to use with my portable charger) was one of the major reasons I bought it. Yet I can only use the supplied adapter and am stuck to the A/C supply.
Anyone else seeing similar problems?

Anyone that owns the tablet will understand what I am saying. The charger cable comes in a 2 piece. A usb to proprietary connector lead and an A/C adapter. You connect the proprietary end of the cable to the tablet. You connect the full USB connector end of the the cable to the adapter. You plug the adapter into the mains and it charges your tablet.
What I am saying is that if I use an alternate A/C adapter (i.e. one that accepts a USB connection and is rated for 1.5 amps and 5V) it does not charge the tablet correctly. I can't see why this would be as these adapters are all supposed to be built to a standard. Sony has something different in theirs I think. I believe it is non-standard.
(There is no USB port on the tablet so clearly this is not what I meant!!)

From what I understand we should be able to use a 3rd party charger if it can supply at least 1.5 amps of current at 5VDC. The only limitations that I have seen is some of the 3rd party iPad chargers (USB plugs) won't work with some android devices so the USB standard must not be as standard as one would tend to think. If your charger is blinking and intermittently charging there is a good chance that it can't sustain the current that the tablet is trying to draw.
Hello Seniors,
I have Samsung Galaxy S3 (I9300) international version and as my charger got damaged, I was using existing Nokia Micro USB charger with output of 5V & 1.2 Amp.
Samsung's original charger has got specifications of 5V & 1 Amp.
When I read about using higher current charger, many places it was mentioned that phone will charge faster. So I was ok to use this charger.
I can see that charging has become faster but the problem is when the phone is charging the screen do not respond to touch correctly.
Once I remove the charger it becomes normal.
So wanted to check if using this charger is there possibility of damaging the phone? And What is the reason that screen do not respond correctly for Nokia charger?
Looking forward for your expert advise....
Regards,
Anoop.

Hi, I had a very similar issue with my old Atrix 2. I too was using a higher current charger because I didn't have the original fitting for my outlets. I don't think the phone took any damage but the screen would sometimes not respond or most of the time just do weird **** when touched...
The 'charging' bit is built into the phone, the charger just supplies a constant voltage up to a maximum rated current. If you use a charger with an insufficient current rating the charge period is extended, like if you plug usb into your pc.
Using a 1A (or higher, makes no difference) rated charger will enable your phone to charge the battery at maximum rate, as long as the usb connector fits you can't go wrong.
Problems will occur if you use a cheap charger, or faulty one where a poor earth can mess with the touch screen. Throw it away and get the older type Samsung (one piece including lead) which are much better quality than the newer three piece ones.
Thanks Boomboomer for your input regarding this issue.
But one thing which I want to point out is, the Nokia Charger which i am using has got no earthing pin at all. It is just a plastic connector given at the place of earth pin. So technically there is no earthing. My samsung charger also did not have earthing pin it has only 2 pins (Indian Connector Style)
So I am not sure if that(Earthing) will be impacting in any way...
Please correct me if I am wrong...
No impact
Your capacitive screen relies on your finger changing the minuscule voltages within the screen, the faulty charger (or lead) interferes with these voltages due to poor shielding (the 'earth' of the usb lead). The charger needs no mains earth connection, but the usb connector shield has to have a good connection to the 'zero' point of the electronics inside the charger.
Try another good charger, or lead, and the problem will vanish.
Not to worry at all, you can even charge with the 2A Galaxy Tab charger. Just do not use black market chargers

I bought this hdmi cable from amazon: http://www.amazon.com/gp/product/B00K61OB6C/ref=oh_details_o00_s00_i00?ie=UTF8&psc=1
I hooked up the tab to the tv, cranked up netflix and nothing. I plugged in the power adapter and got a picture. So needs charger to plugged in to work. I wasn't real keen on the output, but was only testing for connectivity. Might come back and edit after I have chance to adjust settings.
Today, I plugged the cable into the second hdmi port on my tv and it does mirror the tab display. Good response time too.
The charger is necessary but it does not charge the Tab. Left it plugged in and battery was down to 38% before i noticed.
Maybe a hardware error? Because under features it's described that it will charge your device...

Probably not a hardware error. I'm on my 3rd dongle that's supposed to charge your tablet while using connected devices. The latest is this one: http://www.amazon.com/E-More%C2%AE-Multi-functional-Connection-Reader-Samsung/dp/B00K80C9CE/ref=sr_1_8?ie=UTF8&qid=1403104007&sr=8-8&keywords=HDTV+HDMI+Adapter+Cable+USB+OTG+Card+Reader
Everything works except for charging the tablet. Have a red X on the charging symbol while the battery continues to drain. It does charge the tablet while it's off. I have a power hungry Tab Pro 12.2 that has trouble maintaining a charge while playing a couple games with the stock 2 amp charger. I'm beginning to think that none of the HDMI dongles out there are capable of delivering the current necessary to run the larger tablets.
Ah, I see. It's because not enough power through the micro usb. You need 2A but this adapter's only delivering 1A.
It seems, there a no adapters with 2A...
I have a ton of usb chargers gathered over the years. Largest i have is only 5.1 volts. Tab has a large output. Wonder if other devices could be damaged using it or is output regulated by draw of whatever it is attached to? At any rate, i don't think any of the dongles or otg cables have a power source other than what is supplied by the tabs adapter. So are you thinking it is an issue with the pin configuration on the adapter? It is a 11 pin connector. Sure wish there was 1 standard for everyone instead of everyone having their own.

It's not limitated by the pins, there are just for more or less possibilities for an interchange (at least a salesman told me that). It's limited by the inside electronical components. Maybe anybody out there to explain it better or correct my words?
If I remember correctly (it's been a couple years since I tested it), my S3 required the Samsung charger + Samsung wire hooked up to the HDMI (I have the Samsung HDMI adapter) to charge the device while mirroring the screen. I tried it with a more powerful power adapter (2.1 amps vs Samsung 1.x amps) and generic wire but the phone would lose power over time. I could even charge the phone while mirroring if I used a generic Samsung wall charger and Samsung cord that was listed as 0.8 amps.
I bought the official Samsung one a few weeks ago and it is working fine, it also charges the device while using it but you have to connect a charger to the MHL-HDMI adapter.
Sadly I recently flashed CM11 on my TabPRO 10.1 and now the adapter doesn't work anymore. I get picture but no sound Was so happy about getting CM11 official on my device, but this feature is something I can't live without so I'm going to have to hop back to stockbased
HDMI doesn´t work
Hi guys! I´ve bought this one adapter dhgate.com/product/1-1-mhl-11-pin-micro-usb-to-hdmi-cable-hdtv/163941539 I know is not the original one but doesnt work!!!! I did all the steps but nothing. Any idea?? I have installed the original ROM on my galaxy tab t520. I need help!!! Thanks
Hey everyone, so just reading all the comments regarding the HDMI adapter not charging your tab while it is plugged in with the charger, I have also had issues with it and also with my Note2 and the Samsung Smart Dock I use with it. But I did however manage to find the solution to why it would not charge while on the HDMI dock that is connected to my T.V. It seams that if you plug either the Smart Dock or even the HDMI connectors to the HDMI cable first then plug in the charger it will show its charging but will eventually lose charge while outputting an HDMI output, instead, you need to first plug in the charger cable into your HDMI adapter, then plug it into your phone or tablet and finally plug in the HDMI cable into the adapter, I have found this to be the way to keep my phone and tablet charging while also having the HDMI output connected to my T.V..
Hope this helps .
