Chargers

Any risk in using a different charger than the original samsung one to charge the sgs2?
I use a combination of blackberry charger at work, universal micro usb charger downstairs at home, universal car charger and official charger upstairs.
Any concerns with this?

I've been doing that for ages. I use the droid, SE x10 and iPhone chargers with no issue.
As always YMMV

I am using htc's charger which has a higher rating than samsung charger. No problem at all...

I use a Sony charger to charge my S2 , I have not even removed the Samsung one from the box , As long as you use a branded charger will be fine.

I've tried to use Nokia's 1200 mA charger, It did charge the phone but whenever i connected that charger the phone would slow down terribly. So, whatever you use, try to keep it around Samsung's charger's 700 mA.

Ive found that the standard charger is rubbish! I had my galaxy s 4 month and it broke, my wifes galaxy 3 did same and now i dont even bother with the one out the box, just use the usb cable and the adapter i got with my tab.

Absolutely right...my phone is about 1 month old..and the official samsung charger is already broken..not charging anymore..i guess there is an internal wire breakage at the flexible point of the charger becoz when i shake the wire at that point it starts charging intermittently..

Same here. I tried all sorts to get it to work with no joy. I now have 3 duff samsung chargers that are potentially a fire hazard if left plugged in! Tempted to email samsung and raise this concern.

At home I use a Lenmar AC-to-USB 1A charger I picked up at Fry's for around $10; in the car I use a 1A Cygnett 12V-to-USB charger, also from Fry's. Both charge the device at least as well as the OEM AC charger; the car charger appears to charge the SGS2 even when I'm running CoPilot Live.

I use the iGO charge anywhere.
It's a tad pricey, but since the GS2 battery life isn't great (my only complaint on the phone), the charger is great for it since it has an internal battery that charges up when you put it in an outlet so you can charge the phone without needing an outlet. Great for in school or walking around, just put it in my bag and press the button and it charges.

I'm using my BlackBerry charger with no issues, I just do it for convenience as the charging time is the same as the standard charger.

Cheers for the replies, you have put my worried little mind at ease!

+1 .Just used the charger from a different brand and no bad feelings while using it

well, i just emailed samsung raising my concerns regarding the faulty chargers... see what they come back with....

Guys have you noticed any change in response when we plug in another charger?
I have been using the HTC charger, 200 mA (input), Output 5V --> 1A.
Whenever i connect my phone to charge and try to work on it, i see my screen lag terribly. Haven't tried it with the supplied charger though due to the low voltage that came with it.
I know i would be wrong, but wanted to check with the experts on this forum...

200ma is way low, less than half the 500 ma usb standard. Get a new charger. Most of the chargers you are going to see will be 500 ma I would go with double that.

Some (bad?) chargers will disable touchscreen
I have a couple of usb-chargers off ebay and they give some trouble.
When connected, the touchscreen will not work anymore.
This is mentioned in the manual btw.
Guess the SII is a little sensitive.

Yeah, ebay chargers are a crapshoot. Head to walmart or similar and read the power specs, get something that puts out 5v at 1A LPS. This will charge much faster than the often usb based standard 500 mA chargers and the battery will not be harmed at that charging level which is what many stock HTC chargers put out nowdays. Do not get anything less than 500mA, this is the usb standard and works but will be slower to charge. El Cheapo no name chargers on ebay and such may have the spec but may or may not actually put out the juice. You can usually tell this because the phone will have problems like the ones mentioned right here. The stock charger does not put out any special juice, juice is juice. If a charger puts out to spec the phone will work while charging.

Any idea why I can't seem to charge my Nexus 7 with my car charger?
i have both a generic Micro USB charger and I have one of the dual USB ports that you put into the cigarette lighter. It wont even acknowledge that I have plugged anything into it.
i have used the USB port to charge MANY different cell phones my old Dell Streak 7 and even a friends iPad.
Any ideas?

I think the N7 needs 2A to charge. a single USB is 500 mA and the dual 1A, so I don't think there's enough power.
Also check if the output of your microUSB cigarette charger is 2A

well i think that answers my question. thank you

This one will work: http://www.amazon.com/gp/product/B0090SVY3K/ref=oh_details_o02_s00_i00
It charges at the same rate as the stock AC charger.

The N7 is one picky device for charging. I have several chargers for the car that charge the iPad but not one will charge the N7. Same as AC chargers. This set works for me
http://www.amazon.com/dp/B008FF84K0/ref=pe_175190_21431760_M2T1_ST1_3p_dp_1

This is what I use and it works just fine. I use it to charge my N7, GNote, Nook Color or my grandsons IPhone and it works equally well on all of them.
BTW, it prime available if you are a member.

It only charges via usb when the screen is off or when the device is off. Try plugging it in checking the battery % leave it awhile and then recheck the battery % you may find its gone up!

We can only use the LG charger?

Since the battery life of the phone is quite poor it's only natural that i would like to charge it when i'm on class or with an usb cable when im using my laptop, using other usb chargers/cables, but on the manual says (of course) that we should only use it with the lg charger that comes in the box or an official nexus 4 charger .
It kinda sounds like bullsh*t until i remember what happened with my motorola milestone, sometimes when i used another charger the screen started doing crazy things, like swipping the homescreens by itself , oppening apps, until i charged it for at least a few minutes with the official charger, some months later my digitalizer died, so you can imagine how traumatized i am, but then i think what's the point of trying to make a standard out of microusb chargers if we can only use the official charger? what do you guys think?

I find battery life to be very good.
I have been using an old HTC charger on mine without issue though. I suspect the 'only use LG charger' is to cover themselves in case you kill the device with a cheap and badly made knock off.

AW: We can only use the LG charger?
I have literally problems in draining my battery, running Franco's Kernel and Minco v6.
Anyway, using another charger should be no problem. I used the charger of my Asus Transformer and a mobile charger in my car without issues.

Feel free to use any USB wallcharger you'll find.
I tried some i had laying around (HTC, iPhone 5, iPad) and they all charged without trouble.. :good:

Yeah, I've used a 1A HTC charger with no issue. I accidentally left my lg charger at a friends house and had to use what I had.

the battery life is good, better than s2 with its extended battery, i was wondering about this too as i want to use a sony rx100 at 2amps to charge while im traveling.
on page 168 of the service manual it states the max charging current is set at 900mah, over voltage protection upto 28volts

The current should be controlled by the phone, not the charger. Therefore there shouldn't be a problem with more powerful chargers. The voltage has to be correct, though

The phone certainly regulates the power it takes.
If you are really worried about the chargers just flip them over and read the output ratings. Most of them are exactly the same these days.

Any USB charger will work. Note the output current on the charger though, as that will impact how fast it can charge and whether or not you can have the screen on while you charge. The LG charger that comes with the phone is 5v 1.2a, an iPhone charger (at least as of the 4S when I got mine) is 5v 1a and an Amazon Kindle charger is 5v 0.85a. The USB 2.0 spec calls out a max power output of 5v 0.5a.

I'm confused , the lg nexus 4 charger is 5.0v 1.2A and my galaxy nexus charger which i use sometimes with my nexus 4 is 5.0V 1.0A , what does this mean? what's the difference?

My Nexus 4 is on the way so i cant comment on that but my Sony Xperia S acts differently to different USB leads even on the same charge unit. It might charge at 500mAh or 950mAh (on a charger rated at 850mAh), the screen might be fine or it might act erratic and it all depends on the lead plugged in to the charger

I used Samsung/blackberry chargers and they worked. Not sure if they were as efficient though.

I pretty much use anything but the LG charger and have been doing so over a month. So feel free to use any quality charger you like.
I also charge of my Philips Qi pad and off computer USB ports.
As long as it's providing stable power or anything close to it, it's good.
Just be careful with (fake) cheapo chargers. Those might cause issues with the touchscreen going haywire while charging off them. I've also read that about some car chargers, but so far my cheap 2A 2port USB car charger that came of DX is working fine for me.
YMMV of course. But there is no need to stick to just the LG charger.

S4 comes with 2A charger while S3 with 1A charger, can I interchange?

Hello,
Just noticed that S4 comes with 2A charger while S3 come with 1A charger. I have place where I charge a bunch of different devices in the house which has micro-USB port and all of them are using 1A. I'm wondering what repricussions I can have if I add 2A charger to the mix and will charge old devices with 2A charger and vice a versa charge S4 with 1A?

It will be fine, I charge all my devices from my ipad 3 10W/2A @5V wall charger. Bringing one charger while travelling reduces the clutter I have to pack.
Basically if your devices are working properly, they will only pull the power they need to charge. The S4's 2A charger is capable of supplying up to 2A's but is fine supplying less if the device your charging uses less.
The actuall charging circuitry that controls the battery charging is in the phone or device, not the wall unit. The wall unit is simply the power supply.

As acruxksa mentioned, you'll be fine since the device is in control of how much power it pulls from the charger (as long as it is working properly, that is). The only thing that you may notice is when you are charging the Galaxy S4 with the older 1.0A charger it may charge slower.
Have a great day.

And if in doubt, look at it this way; the phones will charge off a USB port on a computer - this is 500ma (0.5A) - so as long as your device will charge off a usb port, it will charge off a wall charger that supplies at least that much amperage. New iPads will not charge off USB ports, but it doesn't hurt them to plug them in.

Yes it does but as the previous reply said it takes longer.
I used the old s3 cable at the office charging s4 but it takes long time to get the battery % up. It usually takes my s4 from 1% to 100% within an hour and half time but with the s3 cable it takes good 3 -4 hour or so.
I wouldn't take the s3 cable for travelling though. it will take too long for me to charge in coffee shops and what not when I am moving around the destinations.
So far, I am very impressed with the charging time of S4.. Love the device.

I don't understand why all current control is on device itself why not manufacturers just suppl 3A chargers for all the phones since it can be used for any device out there.

Good question. Maybe because the higher amp batteries have not been out that long compared to all the years smartphones have been sold. They may start making 3A only. Also, companies may sell less chargers if one size fits all. No need to buy a new one when you change phones.
I do know when I charge the S4 with my One S charger it does take longer, as mentioned, and very slow off USB. The One S charger end also gets somewhat warm charging the S4. The S4 charger does not. That would lead me to believe it is pulling a little more current than charger was designed for. But, probably not an issue. USB does not get warm. But, is a good quality one and heavily shielded.

In case someone buys a 10amp cheap charger and ends up frying the phone. Thus Samsung protects it self from dummy users and from million dead phones warranty swaps.
I'm using a USB car charger that puts out 2.1amps and its super fast. USB 2.0 on my laptop takes a while to charge it. Some times I use iPhone charger with Nokia cable or with WD hard drive USB wire. They all work just fine but charge at different rate.

The bigger the charger, more expensive it is. Manufacturers want to save money.

Wow. Way to necro this thread...

Necro--
Damn, thank goodness for Urban Dictionaries for OLD farts--
Had to look that one up

so if i will charge my S3 with a 2A charger i wont see any major change from the 1A, correct? I have the Boeffala kernel and at the AC charge is set to 1,1A so if i have a 2A charger i guess it should charge faster.

The phone will only draw the maximum it can. The 2A charger will charge it at the same speed as the 1A charger.

Maybe it is a placebo effect, but when I charge my S3 with my S4's charger it does seem faster. Quite a few of my coworkers that have used my S4 charger at work also thought it charged faster.
Either way I have charged my S3 with it very often with no I'll effects, so OP you should be safe to do so.

[Q] Note 4 Car Charging?

Hey guys,
I just plugged my note 4 into my car charger (anker charger, oem note 4 cable) and couldn't get it to charge. It charges my note 3 no problem.
I also have no problems charging my note 4 with wall chargers.
Any help?

I've got the "Anker® 18W / 3.6A Car Charger with Built-in Micro USB Cord for Android" and it's actually CHARGING my Note 4 when using GPS navigation and playing music! My Note 2 wouldn't charge, but it would hold charge under the same conditions.
What model charger are you using?

I actually can't find it on the charger itself or even Amazon. It's relatively new, I thought it was a 2.0/2.1 amp charger (2x USB). Definitely Anker though.

Are you using both usb's at the same time? If so, it's splitting the power, so you'll get a slow charge.

Hmm.. this mentions rapid charging, I wonder if it's as fast as the wall charger
http://www.samsung.com/us/mobile/cell-phones-accessories/ECA-U21CBEBXAR

The only chargers that work with the new fast charging technology are ones that are purpose built and have the ability to switch between 9V and 5V,they are quite uncommon.

I have this charger http://www.amazon.com/gp/product/B00D82O68Y/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1
and it charges my note 4 while running Waze and tethering my Radar Detector via Bluetooth (which also uses GPS)....and it charges my wife's S5 at the same time

Using an afer market 2.1a charger and an S3 cable, charges just fine.

I believe Samsung has stated it's a 9v charger instead of the conventional 5v charger.

Did some more research and found this:
http://www.incipio.com/chargers/car-chargers/quick-charge-2-0-single-port-usb-charger.html#
From the Engadget review, "I clarified with Samsung that it chose a proprietary solution instead of licensing Qualcomm's QuickCharge tech, but it insisted that you could still use QuickCharge 2.0-compatible chargers to achieve the same results."
Also from http://www.samsung.com/sa_en/support/skp/faq/1063730?CID=AFL-hq-mul-0813-11000170
[FAQs] Smart Phone : Galaxy Note 4- To use fast charging, what kind of charger should be used?
Fast charging uses battery charging technology that charges the
battery faster by increasing the charging power. The Galaxy Note 4
device supports Samsung’s Adaptive Fast Charging feature and
Qualcomm Quick Charge 2.0.
To use Fast charging on your device, connect it to a battery charger
that supports Adaptive Fast Charging or Quick Charge 2.0.
